"TAKE THAT DEKU!!" Yelled a 5 year old Katsuki as he released a explosion at him.

Izuku fell to the ground covered in soot and bruises, along with some burns from Katsuki's explosions.

He laid on the ground in sadness knowing no one would help him because he was quirkless.

Word spread around the neighborhood like wildfire and everyone stayed away from him and the kids bullied him.

Izuku slowly stood up trying to ignore his injuries when someone walked up to him.

"Hey you ok?" Said a woman's voice.

Izuku looked at the woman with long purple and pink hair. She seemed to be in her late teens or early twenties and was wearing what looked like a college uniform.

She then leaned down and gave him a warm smile "don't worry I'm a hero and I can help ya".

"R-r-really..." Said Izuku a little worried.

"Yes really. Oh I'm Kaina Tsutsumi by the way" she said with a warm smile and she reached into her bag and pulled out. Some bandages and ointment.

Izuku sat there while she applied the bandages and ointment. He was shocked that someone would be so nice to him.. but he knew it was because she didn't know he was quirkless.

"They're all done" said Kaina with a smile.

"T-thank you Tsutsumi-san".

"It's no trouble. So where's your mom?" Said Kaina.

"A-at home.." said Izuku looking down.

"Ok well how about I walk you home then?" Said Kaina.

"R-r-really?".

"Mhm. Heroes should always help even if it's something small".

She then stood up and gently took his hand and had him bring her to his house.

As this happened a part of her wondered why he looked in such bad shape and no one seemed to care. "I mean come on he's such a sweet kid! I just wanna spoil him!!".

After a couple of minutes they arrived at Izuku's apartment room and knocked on the door and a couple seconds later Inko opened it.

"Can I help you- OH IZUKU WHAT HAPPENED!?" Said Inko in a panic.

"I found him beat up and hurt so I helped heal his wounds and I helped him get home" said Kaina.

"Thank you so much Ms I can't thank you enough" said Inko hugging Izuku before she let him go.

"Hehe it's ok, you have a really sweet boy. Well I should probably get out of your hair so bye" said Kaina who was about to walk away when she felt someone grab her hand.

"Izuku?" Said Inko looking at her son.

"I-I'm sorry but.. would you like to see my t-toys?" Said Izuku.

Kaina didn't know why but she felt inclined too and smiled "if your mom is ok with it then sure".

"I don't see any problems with it. Here let me make us some tea while you do that" said Inko with a warm smile.

Izuku then dragged Kaina away to his room and started showing him all his toys.

They then sat in his room for 10 minutes with him just showing her all his toys and the whole time she had a warm smile that never left.

"And this is my favorite All Might toy!" Said Izuku holding a limited edition All Might silver age toy.

"Hehe I'm guessing you like him a lot?" Said Kaina.

"Mhm! I wanna be a hero just like him even though I'm quirkle-" said Izuku before he stopped.

"Your what?" Said Kaina wondering why he suddenly stopped.

"I... I'm quirkless...".

Izuku stood there waiting for her to laugh at him and say he can't then leave.

But instead he felt a pair of arms wrap around him and pull him into a warm hug.

"That doesn't mean you can't be a hero. You just have to try harder and I'm sure you can be one" said Kaina.

"Y-you really t-think so?..." Said Izuku with tears in his eyes.

"I know so Midoriya" said Kaina.

Izuku started crying and hugged her tightly while she gently stroked his back "it's ok Midoriya, it's ok just let it all out". She then gently kissed his forehead.

After that day she'd come over every once and a while to visit or to sometimes watch over him while Inko left to do something important.

As the weeks then months flew by they became closer and closer until Izuku said something that made her cry in happiness.

"I love it Kaina-Oneesan!" Said Izuku holding a little present she got him for his birthday.

They then started to see each other as brother and sister after that.

Then when Christmas time came around Izuku got her a gift that she never went anywhere without it.

It was a little locket with a picture of both of them together smiling.

Sadly as all of this was happening she kept going down a darker and darker path because of the hero association making her a assassin.

She was getting close to the breaking point but it was thanks to her Otouto that she's still going.

(1 year later)

"What a long day..." Said Kaina walking into her one bedroom apartment shaking.

She could still see all the 'blood' on her hands from all the people she had to kill in the name of "justice".

"HAPPY BIRTHDAY KAINA-ONEESAN!!" Said Izuku popping around the corner startling her.

Izuku went to give her a hug but she panicked because she didn't want the 'blood' on him.

"STAY AWAY!!" Yelled Kaina scaring him for a moment. "I.. I don't want my blood.. on you...".

Izuku looked at his Oneesan in confusion since she didn't have any blood on her. But then he saw the broken look in her eyes that was all but screaming for help.

He slowly walked towards her seeing that she was on her knees crying.

"Kaina-Oneesan?" Said Izuku as he gently took her hand In his and held it "it's ok I am here" he then started to wipe her hands trying to clean the 'blood'.

She looked as her hands were slowly getting cleaned of the 'blood' and felt more tears welling up in her eyes.

"Your my hero Kaina-Oneesan and today let me be yours" said Izuku with the same warm smile she showed him on the day they first met.

All her walls broke and she pulled him into a hug and broke down crying while holding him.

"Otouto... Please let me just hold you.." said Kaina in a shaky voice.

Izuku just smiled and hugged her tighter. He was going to be her hero today.

(3 months later).

"I'm sorry Izuku... I don't think I'll ever be able to see you again..." Thought Kaina as she was carted away to Tartarus prison.

She soon arrived and the guards then started removing everything from her but she kept one thing and refused to let it go. It was her locket and she'd rather die then let them so much as touch it.

"Give it here prisoner" said the guard.

Kaina just glared at him and tightened her grip on it.

She was then thrown into cell covered in bruises and welts from the guards beating her. but she still held the locket tightly in her hand regardless.

Kaina shakily opened the locket and started crying when she saw the picture"I'm sorry... Otouto... Just know.. that I love you...".

(Back to the present)

"Be quiet Baka..." Said Kaina as the memories slowly faded away and she continued to apply pressure to his stomach wound.

"Y-you know something... Your a auntie.. and soon you'll have.. two sisters in law.." said Izuku while focusing his healing quirk on his wounds.

"What!?" Said Kaina startled.

He shakily moved his hand to his hero suit and opened the zipper and pulled out a photo.

"Here's your sisters in law and your niece.." said Izuku.

Kaina looked at the photo and smiled warmly "I'm so proud of you Izuku.." she the brushed some of his hair away and kissed his forehead.

"Kaina-Oneesan.. will you help us.." said Izuku.

"Yes... Besides.." said Kaina as her overprotective older sister side kicked in "I need to make sure those two woman are good enough for my Otouto".

Izuku swore he saw a Oni demon mask behind her floating menacingly.

After a couple more minutes of him healing his wound and then talking with him telling her everything he slowly stood up.

"I really missed you Kaina-Oneesan" said Izuku standing at his full height being taller than her.

She puffed her cheeks slightly and poked his chest "I didn't say you could get taller than me Izuku".

"Hehehe... Sorry?...".

"Come on let's go" said Kaina as she started to walk away.

Izuku smiled happily and took the lead shooting off with her right behind.

This is the first time he's felt happy in a long time and he wasn't going to let it go or loose her again.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"Hehehe.. Boom" said Shigaraki.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"Look I see the o-" said Izuku before he saw Kaina starting to glow and cracks form on her body.

"I'm sorry Izuku... don't loose your family and just know that I lo-"

(BOOOOOOOOOOM!!!!!).

"KAINA-ONEESAN!!!!!!" Screamed Izuku as the explosion blew him away.

He landed painfully on the ground breaking his arm but he ignored it and stood up sprinting to his Oneesan.

"Kaina! KAINA!!" Screamed Izuku as he arrive at the massive crater and saw her body.

"NO!!" He then ran down and picked her up holding her charred body in his arms.."please don't go... Oneesan please... I can't loose you...".

"I...Izuku..." Whispered Kaina.

"Oneesan!".

"I.. it's.. ok..".

"Be quiet I can save you! Just hold on and we'll get you to a hospital!!" Said Izuku as he forced his healing quirk in her.

Sadly he didn't see it working and saw her feet starting to turn to dust.

"No.. no, no, no, no!" Said Izuku as he force activated it hoping it'd save her.

"It's ok.. Izuku..." Said Kaina as she slowly lifted her hand and cupped his face. "I..I'm just... Happy I.. got too... See my... Otouto's... Face one last time..".

"SHUT UP I CAN SAVE YOU!!" Screamed Izuku as he tried to stop the decay from going any further but it already reached her waist.

"I.. Izuku... Just know that.. I love you and... I'll always be proud of you..." Said Kaina as she used the last of her strength to. Pull herself up and kiss his forehead "save.. the others...".

She then turned to dust in Izuku's arms and his eyes were shaking.

"No.......... NOOOOOOOOOO!!!!!!!!!".

"Hehehehe.. so close to breaking cousin.. I only need to twist the knife 3 more times. Until you break and the world sees that even the symbol of hope can be broken" said Shigaraki.

He then turned around and looked at 3 pictures with a dark grin.

One was All Might.

Second was Inko.

Third was Rumi, Ochako, and Eri.

"I'll break you then kill you Izuku" said Shigaraki standing up and leaving to go create more Nomu.
