After yesterday Daidouji woke up in his room which he placed her there to make sure she doesn't sleep out in the open.

Flashback
"Ow!!!, what the hell?, Br-....... wait a minute if I feel that ... does that mean I'm not dreaming and I holding a cute shota (Y/N) at my hands" by that a while of looking at him she have a massive nosebleed and pass out of blood loss.

"Damn it why does this happen of all people" asked the hero a little annoyed at there strange behavior. He sigh and went to his apartment room and place the groceries in there proper place to be. (Y/N) looked out the door and see the women still there but knocked out of massive blood loss he was about to leave her there but his justice voice call out to help her and soon sigh and drag the woman to his room with little resistance of feeling the brawlers strength.

He place her on the living room couch to sleep on with a blanket on her, he soon took off his little jumpsuit and soon do the usual routine of the same thing he do everyday and soon went to bed to end his day.
Flashback end

(Y/N) explained everything to her by that Daidouji took (Y/N) to her school Hanzo academy to show him to her teacher and Hanzō if they might help him.

"Can you?" Asked the hero getting a little impatient. As they walk to the destination Daidouji is holding (Y/N) hand very Firm yet gentle hand felt in his gloved hand.

"I don't know actually but I do know the maybe Hanzō and Kiriya have some Nippo to turn you back .Like I for example you saw me with black hair when I transform , if I can do that I bet they have something to turn back you to a teen ....... than maybe ......I won't go to jail" the brawler whisper the last sentence ,while holding (Y/N)s hand so they can't be separated.

"What was that?" Asked (Y/N) with a raised brow at the last sentence but he couldn't hear it.

"What was what?" Asked the Brawler trying to coverup the last sentence that came out of her mouth.

"Nevermind......"

"and we're here" they stop looking at school and looked like a normal highschool with average people left and right but now it's vacant for a while.

Than the woman pick up (Y/N) without warning like a damsel in distress and with great speed they were inside a room in a split second. " and here we are the hideout of the ninjas of Hanzō". She said with a little pride of herself as a student of the light. She look at (Y/N) wanting to get a reaction from the bite-sized hero and thinking that he looked in awe, amazement or speechless but---

"Okay..." He said with the same expression on his face.

"I expected more of a reaction but I guess that'll do ...... wait here I'll call Kiriya .... KIRIYA SENSEI I GOT SOMEONE WHO YOU WANT TO MEET!" the woman scream trying to grab attention of the middle aged man.

A groan heard in the mist "What do you want now Daidouji do you see I'm busy" said the teacher in frustration and out of nowhere a smoke boom appears and when it clear it showed the middle aged man with a frown on his stoic face "what do you want?" Asked Kiriya who's getting a little impatient.

"I'm here because he needs help" the grown woman point at (Y/N) and when the middle age man saw him his eyes widened.

The teacher gasped in shock "Over all my years of teaching and training I never knew you have it in you.... I'm so proud of you, finally started a new level of responsibility". the teacher said proud of his student.

"What are you talking about?" Asked the brawler who is confused.

"Well I never knew you have a son?" when the middle age man said that it surprise the duo.

"Um...what are you talking about old man?" Asked (Y/N) with a raised brow.

"well he does have the same attitude as you ..... you need to teach him some matters". Assured the teacher.

(Y/N) looked very confused and annoyed at the same time of what the old guy is talking about and has no clue about it He was about to say something but Daidouji beat him to it.

"Kiriya he's not my son .... he's the hero guy that the rumors say and his in a little problem". reassured her teacher.

"What !?..... really I expect him to be ....older what help would he needs". Asked Kiriya.

"He was turn into a shota and i very sure you can help somehow". Kiriya hummed for a moment till he gathered his thought in his head of what should he do.

"Hmmmmmm kinda...but let's talk to Hanzō he might know a faster way." the middle age man ask them to follow him to Hanzō office.

"Might as well" (Y/N) said while following the old man who is lagging behind a little.

The powerful ((Y/N) is the most powerful) group went inside the room of Hanzō who looked surprised seeing him the famous ninja hero in front of him.

"My my over all my years of living I never expected the famous ninja hero to show up in my office" said the elder ninja with a cheerful voice meeting the hero "but I never expected you to be sooooooooooo ...... young!" He yelled out looking shock at the hero not expected to be this young.

"I'm a hero not a ninja" (Y/N) said getting a little agitated of being called a ninja and clearly he is not one.

"sure ....." he said sarcastically then turn his head at the two adults "so what the problem?" Asked the legendary ninja.

"(Y/N) or Jr. here what ever you like to call him was turn into a shota" the brawler said pointing at the hero.

"theirs a nipo to change someone's appearance but it won't last forever so we came here to see if you have a more effective way?" Asked Kiriya.

"hmmmm for a matter of fact I do but it will take a while" he said taking out some alchemy science tools and bottles and a book "let's see......... I might need some help Kiriya if you could be so kind to help me" he said having trouble with the book by that Kiriya sweat dropped.

"Okay..... but wait what about class who's going to teach them while I'm busy helping you here". Asked Kiriya realizing he has duty of a teacher.

"well that's no problem we have Daidouji and not mention the famous hero ninja here to teach the young ones ...... ok Jr. I give you the bottle if you become a teacher in this academy until the bottle is done ok?" Requested Hanzō.

"I'm not sure if I could do that..." Rejected the Hero, due to have nothing to teach them anything involving a ninja but he's a hero when we'll they learn..

"Well good luck being a kid forever then" said Hanzō nonchalant, and soon (Y/N) was suprised and soon pleaded to change what he say.

"Wait......"

"Yes?" Asked Hanzō

"Wait....I'll do it....."he said in defeat " but what can I teach them, I have nothing to teach them about and besides I'm not a Ninja who is sneaky, who be in the shadows...Im a Hero for Fun".

"hero ........ if what you say is true did you ever have to solve problems or fight anyone ?" said the elder.

"Well countless of times, they were so many I couldn't remember some of them" (Y/N) said both honestly and dishonestly because most of the battles are mostly fought by Saitama and some he does fight on his own from time to time.

"Than teach them how to become heroes, show them that they must be brave, respectful, honor and show them justice...if you're hero inspired them to become heroes!!!" He said standing up and doing poses of a hero while giving a speech to (Y/N).

"Okay..........." He said while the adult looked with a sweat drop.

"Than we're in agreement......class begins at 9 o clock" (Y/N) and Daidouji walk away to get ready.

"Mister Hanzō are you sure that was a great idea?" Asked Kiriya.

"I don't know I thought it would be amazed just to see how it goes.....now" he looked at the book "how do you read this" the elder said confused at the instructions given.

"Fine give it to me" he sweat drop grabbing the book from the elders hand.

Back to (Y/N) and Daidouji

(Y/N) was walking along with Daidouji were walking down the halls of the academy and was annoyed of teaching the school something but once again he has nothing to teach about.....

"You'll be fine don't worry about it" the brawler reassured the hero.

He grumbles "Fine but I'm only doing this once......" And soon they stopped to the destination of the class he is about to teach.

"wait here (Y/N) I'll build up the excitement" she said with a thumps up and after that she kicks open the door surprise the elites.

"Daidouji senpai!!!!" the elite were surprised by the suprised entrance she made and we're cut off whatever they were doing.

"Today we have a new substitute teacher so be well behave ...... ok you can come and show yourself" the grownup called (Y/N) to the scene, while Daidouji walked out to leave everything to the Hero.

And soon (Y/N) made a average impression on presenting himself.

"Hey what's Yoza little brother doing here .... what's was his name aaa oh yea afro" Katsuragi fallen for Yozakura brother scheme he and she made.

"My names not Afro, and not her brother it's me Jr. The hero for fun don't you remember you fought me when I was fishing" he said rehashing past moment when they first met and is getting a little annoyed of being called Afro.

"oh yea...... hey you pull my skirt and call me a blonde idiot you little brat!" Yelled Katsugari getting a little angry.

"Hey don't call me a brat!!!!!, I did it because Yisakuna made fun of me by giving me that dumb name and I went revenge for giving me that" he said very agitated of being called a brat.

"I pretty sure you said that name wrong ...... but was wrong with you....you look younger" she said no longer angry but has a sweat drop on her head.

"Well Uhhh...." Trying to remember the Crimson squads names "Hinruki, Hominu, Kirai and Komi did this to me" He declared there names wrongly.

The elite didn't know what say except that (Y/N) say those names wrong.

"Um Mister I very sure you said this name's wrong" Ikaruga sweat drop at this.

"hehehehehe he's funny" Hibari holding back some laughter in her system.

"Well no time to waste roll call you know the rules rise your hand if your called ..... let's see" he checked the list " ...... Oscar?"

"aahhhh its Asuka"

"Karakara?"

"What.... its Ikaruga"

"Casca?"

"My name starts with a k not a c!"

"Yoga?"

"Hmmmmmm .... its Yagyu sir" while everyone have to face the wrath of (Y/N) saying their names wrong Hibari was holding a lot of her laughter.

"Hippy?"

"Hey that's not my name?!" everyone but Yagyū were now holding their laughter knowing the meaning of the name.

"Okay everyone lets start....I guess, first what you guys what to do?" Asked the Hero.

"Well first we read about history, than we give you a summary about life force than after that PE" Ikaruga said.

"PE!, Oh I can't wait to train under the famous ninja hero" the blonde said exactly to see what (Y/N) has in store for them.

"Okay......but first do you guys have any questions here?" Asked (Y/N)

"Are you really teacher material?" Ikaruga said who raised her hand first for (Y/N) to see.

"Uhhhhhhh.....no I'm just a guy who's a hero for fun" he said once again crossing his arm while his cape flutters.

"Huh were did that wind came from?" Asked Asuka confused not feeling wind on her but on (Y/N) for some reason.

"It's called dramatic effects Asuka" concluded Hibari.

"Okay everyone focus we have a lot of work to do" he said seating on the chair and picked up a random book rather then the assigned books given to them. "Black and white?"

"That story is usually about warriors" Asuka mentioned

Timeskip

After (Y/N) was reading the book (with lots of errors) he decided to do some training with the girls.

"Yoga do 10 more laps, Katakana and Casca hit the dummies a little harder, Oscar and Hippy you only have 10 minutes to fisnish your match" everyone growled at (Y/N) saying there names completely wrong.

___________________________________________________________________________
Somewhere

"Ok, drop three drops of Samurai blood" Kiriya said reading the book.

"Okay.....one....two..." He said dropping two small pints of blood.

"Put three of you want to expl-Oh shit.....Hanzō stop!!!!" Screamed the teacher.

Hanzō overdid it and took Kiriya word of using 3 instead of 2. "Huh did you say something?" It was too late he already drop the last drop of blood.

KABOOM!!!!

"Hm?" He heard a small explosion that cut him off as he ended a dummies life with ONE Punch.

"(Y/N) how exactly do you got so strong?" Yagyū said wondering how he got so strong.

This made him stop.

"So you want to know my secret as well? He asked with a serious face. "Okay Listen up all of you" he said while thinking "you really want to know?"

"Yes.....I want to know....how to be strong enough to protect everyone dear to me" by that everyone listen to hear his secret to his amazing power even Daidouji who's in the background wanted to know as well.

"Okay.....what's important is to really stick to this intense training regime". He said with a danger smile.

Yagyū and everyone who was listening sigh out of disappointment. "Fine your the boss" she said going back to training.

"I'm not finished yet..." He said who's not finish what he has to say.

"Huh?.....than what were you kinda say?" She asked, her and others wanted to know more about it.

"Listen, you have to keep doing it, no matter how difficult it gets, it took me 4 and a half years to get this strong...."

"50 PUSH UPS, 50 SIT UPS AND 50 SQUATS!!!!!!.........." They looked in shock and was silent "And a 5 KM Run, Do IT Every Single day!!!!" He shouted the top of his little youngs as he strike up a serious face yet again.

"What's important is to eat 3 meals daily an apple in the morning is fine...Never ever use air conditioning in the summer or heat in the winter so you could strengthen the mind, I thought about giving up but my dad encourage me to keep going and fulfill to be a strong hero as he is so I toughed it out and endure that horrendous pain, I did squats when my legs couldn't move and felt very heavy or when I did push-ups makes weird clicking and popping noises left and right I still did push ups!!!"

"....2 years later I notice a huge difference..."

"....MY HAIR WAS SHORTER AND I BECOME STRONG!!!!....So train like hell to the point some of your hair falls off is the only way to become truly strong" he finished with a serious anime pose with a clenched fist at some of his long beautiful hair gone with a toll of getting stronger.

Everyone was shocked and not believing at the same time they didn't believe because it was too simple and very plain level and shock because if they do that type of training every day they will lose all their primary feminine charms. (And that is hair)

"No way I don't believe that is to simple!?" Katsuragi screamed not believing that all he did to get strong.

"Yeah if that was true we will look like boys!" Ikaruga yell while holding her hair.

"I usually don't agree but theirs no way....... But I still love you I'll do it !!!!!" she went down and do 50 push ups everyone sweat drop at this .

"Well it looks like a love attack again" Asuka said sweat dropping.

"If it's to become stronger than I'll do it" Yagyū said joining the brawler than every join in to not fell left out of doing it.

"Keep doing it, but not much because you will lose all your hair" he said remember Saitama lost all his hair and become bald like an egg.

___________________________________________________________________________
Hanzō's office

"Careful, careful, Hanzō sensei be careful" said the middle aged man covered in soot mist thanks for the explosion.

"ssssssshhhhhhhhhh let me focus" said the old man also covered in soot. He slowly put the last drop on the tube and she he did the two ninjas took cover but nothing happened.

"fuu I thought something bad gonna happen" said Kiriya finally relieved of no explosion happened.

"Don't be so relaxed we still have some more to do" this put them a sigh of disappointment but was cut off when two hear bubbling and bubbles going crazy and than they saw some blob coming out and moving around.

"Huhhhh??" The two were confused by this and than the blob have eyes popping out than grew bigger and roar at the two men.

ROAR!!!!!!!

"OOhhhh Shiiiitttttt!!!!"

___________________________________________________________________________
Back to (Y/N)

"It was lunchtime for the Hanzō elites and the Hero, (Y/N) was eating a bowl of rice, an apple and some Fukimaki rolls that Asuka bring, they were eating peacefully while Daidouji was looking at (Y/N) eating with lust and hearts flying around her.

"Oh my (Y/N) he's so cute when he eats, it almost makes me crazy" than she saw (Y/N) have a little rice on his cheek by that she have a nosebleed of what she's to do by her jumping to catch (Y/N).

"Let me get that for you (Y/N)!!" But her plan was ruined when Ikaruga have a tissue to wipe the rice away from his face by that she sat in the corner of the room disappointed.

"Thanks" he said and continue eating with silence.

"So mister (Y/N) do you have friends were your from" Asked Hibari curious of what his friends was like.

"Yeah but not that much I wouldn't called em friends but acquaintance and dad have few as well" which was slightly true of (Y/N) having little to no friends like genos, Mumen rider and some S-class heroes but Saitama have very few for his low class ranked.

"Well it's a good thing that you have people you can talk to" Asuka concluded.

"Yeah sure is..." He said as he continued eating.
___________________________________________________________________________
Hanzō's office

"Okay Kiriya are you ready?" Ask Hanzō now wearing armor.

"Okay I'm ready for this" said Kiriya also wearing armor than dripping one drop into the tube and when it did, smoke surrounded the office.

The old man coughed "are you okay?...wow...." Said Hanzō looking at Kiriya who has longer hair that made repunzel jealous and out of shame and for the first time ever a mustache.

"Ha Ha Ha very funny Hanzō....The puppets called and they want there member back" shot back Kiriya.

"Eh?????" He said looking at himself that he look like a big puff ball. "..........bring the chainsaw"

Back to (Y/N)

'What's taking them so long!????' He thought knowing that it's taking a very long time for them to be him agian.

It answered his call as the Microphone speaks up loud enough to hear.

"Can muster Saitama Jr. Come to my office please were find oh with the potion.

"Finally I could be me again" he got back up and went to the office to claim his callings.

(Y/N) went to Hanzō office and it was a mess of black soot on the walls, slime on the ground or ceiling and hair was everywhere.

"It was brutal but it was worth it to let one of my students learn your ways....a deals a deal." Said the old man.

"Thanks" as he got the potion out of the old mans hand and drank the bottle hastily and it tasted sweet but sour at the same time and soon a purple glowed emitted around his body till the mist disappeared.

He is now in his teen years again.

"Good as new or should I say good as old" (Y/N) joke a little but Asuka went inside the office .

"Hey grandpa could you make more......." when she looks at (Y/n) her eyes turn pink and in her point of view he saw him in a chief uniform with very sharp eyes

(I'll make my own version some time soon)
by that her eye have hearts on them by that she launch herself at the hero "I love you !!!!!"

"Eeeh?" And soon she the female ninja opened her arms for a hug but (y/n) evaded it and looked confused.

"What did you just do?" Asked the hero panicked.

"Oh my..." The old man looked at the boom again "It looks like it have some side effects not only it's a growth potion it is also a love potion it will make the one who drink it is irresistible in the eyes of the opposite gender. Concluded the old man once again.

"The hell?!" He screamed out in suprised as he continue to evade the ninjas hugs and counter hugs "well undo this!!!.

"It's a side it will wear off sometimes I guess 2" said the middle aged man.

"Is it 2 minutes or hours?" Asked the hero hoping it would be 2 minutes or even seconds.

"Hey what's with all the rack-....mmmmmmmm" when she saw (Y/N) her eyes turn pink and her view she saw him in some type of samurai armor with a heroic look on his face.

"Oh my mister (Y/N) I never saw this side of you before, I think I'm in......Love!!!!!" Her eyes turn into hearts as well and successfully launch herself to (Y/N).

"Hey get your own he's mine!!!!!" Screamed Asuka who got (Y/N) on the other side.

"All roar in war when it comes to love" she shot back and the two females were standing and still hugging him.

"Why me......" He said with crocodile tears in his eyes.

"Come on this is a dream come true for any man" the old man said in jealously of (Y/N)'s misfortune of the two females fighting over him"

"Just hope you don't knock up my granddaughter or you'll will see" said Hanzō as a warning if that happens he will have a bad time with the legendary Shinobi (not really).

Epilogue
Back home.......

Back in City B rural area
Saitama Was Standing On The The large hole in the ground where (Y/N) was last seen at sundown...he come here all the time when he's not on patrol and do hero activity.

"Hello Sensei" He turned his head and see his 'Disciple' Genos

"Hey Genos" said the Hero for fun plainly.

He came to stand with him and look down on the hole silence flooded the area around them.

"Sensei....you can't keep doing this...you can't let this eat you up"

"What are you talking about?" Asked Saitama.

"I'm talking about (Y/N)...you can't let his death get you down" concluded the cyborg concerned for his masters health.

"he's Not Dead"

"What?"

"He's not dead...we survived worse than this...he find A way out like he always does and I'm waiting for him to get home" said Saitama looking down at the ground.

"Sensei you can't seriously think that he's...." But the cyborg was cut off by the his master denials.

"Please don't tell me because he's dead"

He look to see something that shocked Genos to see Saitama crying as his eyes closed in pain or physically but mentally.

It was a moment of silence

"Just leave me be...I'll be fine"

He turned back at the hole

Genos stand there for a moment and walked away to give his master some time alone and felt the same way since that very day.

"I Understand Sensei...I See You Later...And Please Get Some Sleep" said the disciple.

"Yeah sure"

He was know standing alone again

"I Know You Still Alive Kid...Just Please Don't Let That Damn Monster Took Over Inside Of You...Just Fight It...Like You Always Have...And Come Back Home For Me...Please...Daddy Miss You" Saitama said while leaving the hole and left (Y/N)s special possession that held dearly his necklace.
