A/N: hey guys I hope you enjoy this chapter cause there will be a lemon soon for this story now enough of my rambling let the chapter begin

3rd pov

in a ally way Y/n and Sakura where on their date when the two finally confessed their feelings for each other now they are confronted with two people one woman named Asuka who was once a member of the Taimanin now turned UFS agent and the other woman named Ingrid who is a demon knight who works for Edwin Black now as Y/n unleashed his mangekyou sharingan as Sakura was defenseless since this was meant to be a date before either one could make a move Asagi and her friends came down next to Y/n and Sakura

Sakura: wha?! sister what are you doing here with the others as well?

Asagi: well Rinko was sensing demonic energy from Y/n and thought he was going to do the same thing as my ex but I guess we we're wrong and it's also surprising that Y/n has the mangekyou sharingan

Y/n: I'll explain that later right now we got to deal with a demon knight and UFS agent

then Y/n used his chakra to summon two short katanas and hand them to Sakura as he stayed weaponless confusing Asuka and Ingrid

Ingrid: your not going to use a weapon fool?

Y/n: I have trust in my own skill with and without a weapon so if I were you I would not underestimate your opponent 

with that Y/n disappeared and reappeared in front of Ingrid with his hand covered in a blue lightning

Y/n: chidori!

once the attack as near Ingrid just barely blocked it with her sword but getting burned by some of the lightning around and getting knocked back by the attack then Ingrid tried to swing her sword at Y/n but he quickly blocked with a kunai he had hidden in the sleeve of his shirt then he kicked Ingrid up in the air out of the ally then followed up by striking Ingrid with his kunai knocking her to the roof tops then Y/n landed on the roof a couple feet away from Ingrid

Ingrid: I must say your quite skilled it's not easy to catch me off guard or lay a hit or two on me

Y/n: thanks I appreciate the compliment from a beautiful lady like yourself even if your a demon

Ingrid: *giggles* flattery will not help you in this fight but I do appreciate the kind words last member of the Uchiha

-with Asagi's group about to fight Asuka-

as Y/n fights Ingrid on the roof Asuka started her fight with her old comrades and friends Asuka was clashing with Shiranui Asuka was using her cybernetic limbs that had blades on them while Shiranui used her spear then Asuka dodged a strike from Shiranui then kicked her down to the ground

Asuka: your good but I'm still better

then Asuka dodged and deflected some shots from Yukikaze's pistols then Asuka launched her cybernetic arm at her hitting her in the stomach as the limb came back to Asuka and reattached to her body then dodged a strike from the brother and sister taimanins Rinko and Tatsurou then Asuka charged and did a couple slashes on both Rinko and Tatsurou then with a powerful punch and kick on them knocking them out

Asuka: even with the brother and sister paired they were no match for me now *looks at Asagi and Sakura* for you two

the two sisters get ready with Asagi having her katana drawn while Sakura was using the two short katanas she got from Y/n then the three started to charge at one another once the three were close enough Asuka used both of her cybernetic arms that had the blades out to clash with both Asagi's and Sakura's weapons locking them but Asuka broke the clash and kicked Sakura back and did a relentless assault on Asagi  who was blocking and parring each but still was having trouble keeping up then Asuka did an upward slash making Asagi's sword go up with it then Asuka followed up with a power punch to Asagi's stomach knocking her back and weaken by the punch

Asuka: pathetic not even the 'great' Asagi can beat me what a disappointment

then Asuka gets knocked back by a kick to the face she then recovered from the kick to see that it was Sakura who kicked her

Asuka: well if it ain't the little sister of Asagi and the girlfriend to the half human half demon Uchiha boy

Sakura: I'm not going to let you hurt my sister or the man that I love!

-back to yours and Ingrid's fight just during the fight Asuka and Asagi's group-

at the roof Y/n starts his fight with the demon knight Ingrid who both are clashing their weapons with quick strikes to one another then Ingrid did as vertical strike knocking Y/n's kunai out of his hand then she was about to follow up with another slash but Y/n dodged it and sent out a couple fire balls from his mouth aimed at Ingrid as the attack connected Ingrid managed to block the attack with her sword

Ingrid: your good there but I'm still better your little tricks aren't going to be enough to beat me

Y/n: your right *pulls out a scroll* then I'll just have to use this

then as he said that a large puff of smoke burst around him then a glowing f/c light was seen through the smoke as it began to dissipate Y/n is seen with a sword that shock Ingrid

Ingrid's thoughts: no way how does he have that sword the only person I knew how had it was a demon Kunoichi who was a friend and mentor to me and Lilim who is he?

Ingrid: tell me how and where did you get that sword and you better not lie to me!

Y/n: *looks at the sword as a tear come down his face* it belonged to my mother who gave me this sword after her and my father were killed by demons by a man named Edwin Black

this shocked Ingrid to her core cause she thought the one person she looked up to died by someone from the Taimanin group before the person that trained Ingrid and Lilim was killed she kept in contacted with them and told them she had a son once word came out she was dead both Ingrid and Lilim vowed to find their mentor's son and protect him then Ingrid falls to her knees and drops her sword which confuses Y/n

Ingrid: I finally found you the son of the Kunoichi demon clan the son of M/n

Y/n: *shocked* huh! how do you know my mother's name!

before she could answer an explosion was heard as they looked to their right they see Sakura land on the ground of the roof badly hurt as Asuka lands slowly walking near her

Asuka: you put up a good fight Sakura but you and everyone else are no match for me *stops close to her preparing to finish Sakura off* it's been nice knowing you Sakura

as she swung down as Sakura closed her eyes waiting for the final blow but it never came and a sound of metal clashing was heard as Sakura opened her eyes to see Y/n in front of her blocking one of Asuka's blades with his mother's sword then pushed Asuka away

Y/n: you keep your hands off my girlfriend or your going to regret it

Asuka: that's funny coming from a demon hybrid the concept of love can not happen

this angered Y/n as a f/c aura flowed visibly around him he then charged at Asuka as both used their weapons clashing with one another with their blades then with another slash they locked their weapons creating sparks from their clash then Asuka broke the clash then kicked Y/n back then used her free cybernetic arm to launch it's rocket punch feature at the defenseless Sakura Y/n was about to use his kamui but Asuka quickly strikes him as he quickly dodged as he sees the fist about to hit Sakura but Ingrid quickly blocked the cybernetic fist pushing it back then Y/n broke the clash and quickly power punch sending Asuka as her cybernetic fist but Y/n wasn't finished he quckly put his sword into the sheath powering up an attack then rushed to Asuka and send a barrage of slashes at her cybernetic limbs destroying them then finish with a punch to the face knocking her out

Y/n: *looks at Ingrid* thanks for protecting Sakura for me but why did you do that? isn't she your enemy

Ingrid: true she is but me and another demon had made a promise with our mentor to find and protect him and those he loves even if they are Taimanin

then everyone from Asagi's group got to the roof once they recovered from Asuka's attacks and see that Asuka is unconscious and her cybernetic limbs destroyed then notices Ingrid standing over Sakura they were about to bring out their weapons but Y/n stops them

Asagi: Y/n what are you doing get away from her!

Y/n: hold on she is not going to hurt you she knows my mother she won't hurt you guys

Rinko: how can you be sure?

Sakura: *slowly gets up* he's right she defended me from Asuka's punch and said that her and another demon made a promise to find their mentor's son to which is Y/n

then Ingrid put her sword away to show that she is not her to cause trouble as the other slowly relaxed knowing that the demon knight Ingrid was not going to fight them then Y/n looks to Ingrid as he was about to ask her something suddenly Ingrid get hit by two projectiles shocking everyone as Ingrid falls to the ground but Y/n quickly catches her and lays her down softly

????: my my I was not expecting the demon Knight to betray lord Black for a stupid Uchiha half breed

as everyon except Y/n looks to see a girl with light pink hair as she was holding needle like projectiles in her hand

Asagi and the others: Saya!

Saya: *giggles* in the flesh I'm not here for you Taimanins just to take out the "demon knight" and the half demon Uchiha and take his eyes

as Ingrid was slowly losing blood Y/n was trying to stop the bleeding as he had tears in his eyes trying to save the one person out of two who know his mother Ingrid then puts her hand on Y/n's cheek

Ingrid: it's okay don't be sad don't listen to what she said your more then a halfling *puts her hand to his chest* your mother would be proud of you

in that moment Y/n felt a hand got to his shoulder as he looks to she an apparition of his mother giving him a smile then leaning down to his ear

M/n: accept who you are and follow your heart my brave half and half

https://youtu.be/-WpnPSChVRQ

A/n: play this song

then Y/n stood up with Aura flowing around him spiking up making Saya and the others take notice then Y/n glares at Saya with his mangekyou sharingan glowing brightly

Y/n: your wrong Saya I'm more then just a half breed I'm a demon with a heart *unleashes his aura* of a human!!!!!!!!

then Y/n's mother's sword flew right into his hand unleashing a bright pillar of light making everyone cover their eyes as it died down they see Y/n looking different with glowing f/c wings and horns

Saya: n no way such power!

Asagi's group: such a pretty color

Y/n: you have made a great Saya *sword gets covered with black flames* feel the flames of the Amaterasu!!!!!

he then launches the black flames at Saya who just barely dodges the flames but still received some burns

Saya: his power has certainly increased more than I expected

what she didn't notice is that Y/n's speed increased as well as she looked behind her Y/n unleased a flurry of strikes on her so fast that she can't even react to them in time then with one powerful punch to her stomach sending Saya flying into the ground of the roof as Y/n slowly descends Saya gets up

Saya: screw this I was not expecting for him to unlock his demon powers

A/N: stop song here

she then used a smoke bomb to make her escape as Y/n walks to Ingrid using his increased healing chakra on Ingrid to heal her wounds as his demon aura and powers died down and deactivating his mangekyou sharingan to his normal e/c but they look dull then Sakura goes to him

Sakura: Y/n are you okay?

Y/n: yeah I'm okay just tired can you take us to the Taimanin HQ and take Ingrid with us *passes out*

Sakura: *catches Y/n* oh boy the boss is going to be grateful but also not going to be happy about Ingrid

to be continue
