-3rd person POV-

we see Issei and his date "Yuuma" going around Kouh Academy. because Issei is showing "Yuuma" around the place.
when they were walking they met Issei's friends (I forgot their names. but they were dumb characters) they had a quick conversation mostly
of Issei just bragging to his friends about getting a "girlfriend" and they didn't and that they should hurry up and get one.

They were taking it badly by being sad (like beta males) and eventually Issei and his "girlfriend" left his friends and continued around the school when they were walking around 'yuuma' looked up after senising someone watching her, and to her not suprise she found a male staring at both her and Issei, normally it would of just been her due to how she looks, but also Issei was kinda acceptable if it was jealousy, but no this person looked at them with a...

Judging look.

so she did the normal thing and asked Issei who he was.

Yuuma: "hey, Issei. Who's the guy in the black jacket on the roof?"

Issei looked up at the roof and saw him and replied to his girlfriends questions.

Issei: "Some new teacher for the best academic students, I don't have his class though."

Yuuma wanted to know his name, not what he does. but the guy walked away.

Yuuma: "But what's his name?"

Issei: "It's. Dr. Oliver Wells"

Yuuma thought there might be more to him then meets the eye. But for now she was busy doing other stuff like killing Issei later and after that taking a nuns sacred gear.

Yuuma: "Ok, but he looks kinda too young to be a teacher though."

Issei: "I know it makes me wonder just how smart is he."

-with Y/N-

Y/N: "I hate it. I hate seeing him."

Y/N said pacing back and forth on the roof. just then the door opened and from it came Souna Sitori. Souna walked to the wall where Y/N was standing next to. she then asked him a question that has been on her mind.

souna: "Dr. Wells, Why did you become a teacher when you could've become one of if not the leading person in the field of science and engineering? I'm sorry if this is random, but the questions been bothering me for awhile, and I needed it answered. So I figured now was the perfect time to ask."

that made "Oliver" chuckle.

(I'm going to use Oliver when another person is around and they don't know who you really are and what your real name is.)

Oliver: "Well Miss Sitori, I did it because I wanted to give my knowledge to people I knew would do great things with it. So does that answer your question council president?"

Souna: "yes, yes it does. thank you for clearing it up for me."

Oliver: "well then I have a test i must complete for my classes this afternoon. So you might wanna prepare for it miss sitori."

he then started walking away and right as he was about to open the door he turned around with his hand still holding the handle to the door and looked at the student council president.

Oliver: "I expect you to do great things in the future miss Sitori. even though I have only tought for one day, I've seen potential in you, so shoot for the stars kid."

and with that he left leaving the Student Council President to think about stuff. she was expecting him to just leave without saying anything he actually ecknowledged her intelect after only one class. which coming from someone with a huge intelect to ecknowledge someone like a highschool student has to be either losing their mind or they actually saw a great potential in them.

-timeskip to next day-
(saturday)
-Issei's and Yuuma's date-

So issei and yuuma are on their date going places. they went to a food place and Issei got Yuuma a ice cream, but unknown to them they were being watched by koneko who was fully healed from the one sided fight with y/n, but unknown to even koneko was that the Reverse Flash was watching issei too.

eventually Issei and Yuuma made it to the park and they walked to the fountain and as they did Yuuma asked Issei.

yuuma: "Hey Issei would you do something for me"

Issei: "ye-yeah anything"

Yuuma: "great, so... would you die for me?"

she asked a a couple of feet away from Issei who was cleary baffled and afraid so he did the logical thing that any scared little boy would do and said.

Issei. "I-i don't think I heard you correctly could you say that again?"

Yuuma then walked next to Issei and whispered in his ear.

Yuuma: "Would. You. Die for me?"

Issei then backed up as yuuma hopped onto the ledge of the fountain and transformed into Raynare (shocker isn't)

Issei: "yuuma, w-w-what's going on?"

Raynare: "it isn't personal kid. if you want someone to blame then blame the guy up there"

she said pointing up confusing and scaring Issei, because one he doesn't know what she meant by "guy up there"
and he's scared due to the fact that she's flying with wings and has a light spear.

in the bushes koneko contacted Rias telling her that he's introuble and that he's going to die.

Issei attempted to turn around and run but when he turned around he saw a glimpse of The Reverse Flash and that made him forget that 'Yuuma' was trying to kill him and turn around and try to run in the direction that wasnt facing towards the guy that murdered his sister.

Raynare then threw the light spare at issei hitting bim in his chest damaging his vital organs, making him fall over and start bleeding out and as he was dying he saw the man that murdered his sister walk up to his side and squat down to look him in the eyes.

(RF= Reverse Flash)
RF: "how's it feel to die hyoudou, painful isn't it? But, soon enough your learn what real pain is."

and with that he sped off leaving a dying Issei who was mad that the man that Murdered his sister, watch as he died. And he also left a koneko who was visibly afraid.

Rias then came and reincarnated him into her pawn, healed him, and then dropped him off at his house.

(next day at school)

Y/N was watching Issei from the roof as he entered the school building and when Issei got into the school Y/N was about to leave so he could continue watching him, but he bumped into Souna sitori who was also there, getting some fresh air.

Souna: "oh! sorry abut that Dr. Wells. I didn't know you were up here."

Oliver: "It's ok miss Sitori, it's expected you don't know my tendencies to get fresh air every morning becuase I'm new teaching here"

Souna: "makes sense , and I will keep that in mind for the future."

Oliver: "I hope you do, now if you excuse me I got to get to my classroom. I still have stuff that needs preparing for this afternoons lessons."

(timeskip to lunch break)

Issei and his friends were walking through the halls, heading outside to peep at girls. But issei suddenly fainted gaining the attention of everyone, but was caught by "Oliver".

the kids started gossiping and Issei's two friends asked "Oliver" if Issei was alright and to that he replied.

Oliver: "He's fine, it looks like he fainted I'll take him to the nurses."

and with that Issei's two friends were about to ask more questions but "Oliver" was already walking away caring Issei.

Oliver: "You two should go back to what you where doing before this, I've got it from here."

they said ok and went outside to do what they do peep at girls.

(timeskip to when Y/N gets Issei to the nurses office.)

when the unconcious Issei and Y/N made it to the nurses there was no one inside so Y/N put him in a bed that was in there. and grabbed a chair, put it next to the bed and sat down waiting for him to wake up. so he waited five minutes and still no nurse showed up. so Y/N knew she was on her break for the hour.

Y/N: " *chuckles* You look so young."

he then stood up and staired into the shut eyes of issei.

Y/N: "Like I could kill you... right now"

his hand started vibrating and he started lowing it but when he got 7/10 of the way his hand had a red lightning streak on it and he stopped. and turned around and started walking to the nurses desk.

Y/N: "What I wouldn't have given... *sigh* all those times before I've had you like this."

he then grabbed a round thing off the nurses desk and put it back down. and started walking back to issei

Y/N: "So.... helpless!" he said "but fate. it's tricky, isn't it?,

he then looked down at issei.

Y/N: "I come here to destroy you, and then to get home I have to be the one who creates you."

and with that he sat back down and waited again.

the nurse eventually came in and uh she was kinda freaked out that there was a another teacher in there with a unconcious child. she calmed down after Oliver/ Y/N explained what happen to her.

she went to check Issei for any injury and found none. Issei eventually. woke up and asked where and why's he's here.

Nurse: "well your in my office. The nurses office, becuase you fainted, and another teacher briught you here."

issei: "wait, how long was I out."

Oliver: "six hours, welcome back Mr. Hyoudou. you have a lot to do"

(timeskip to after Issei leaves and gets attacked by the fallen angel)

Issei got attacked by a fallen angel dohnaseek (did I get the name right) and issei getting saved but the suprising thing is that issei's wound was healing itself, not as fast as phenex's heal but it was healing faster then a normal supernatural being would."
