Sae who is in her apartment living room was checking the old photo book of here family before the death of her father and before she abuse/neglect/abandoned towards her younger brother Y/n.

Sae: I'm sorry*sniff* Y/n. I've sinned to harm you...*sniff*.

Makoto: sis?

Sae:*flinches* huh!? Oh h-hello sis!!

Makoto: sis, what's wrong? Why are you crying? Why do you have our old family photo book?

Sae: why are you ask these questions?

Makoto: because I've met Kirito!!

Sae: w-w-wait you're actually serious!?

Makoto: yes, he's also another persona user just like me and my friends!!

Sae: I see....

Makoto: let me see the photos.

Sae: wait no!!

She sees the old photos and gasped that Kirito is in the family photos.

Makoto: explain now!!

Sae: Kirito isn't his real name, his real name is Y/n and he's your brother. I've checked our old photos and he's the one who defeated Laughing Coffin before Shido and he's 17.

Makoto: but why?

Sae: I abused, neglected and abandoned him because he "killed" our father and called him a burden to our family....I'm sorry.

Makoto:...

Sae: sis, I'm sorry....

Then she cut off by a slap on her right cheek, Makoto was not happy but in tears, with anger and sadness within her heart.

Makoto: AFTER THESE YEARS I HAVE BROTHER YOU CAUSED HIM TO RUN AWAY BECAUSE YOU THINK HE'S A BURDEN!? HOW COULD YOU!? DON'T EVEN THINK ABOUT TALK TO ME AGAIN, SAE I HATE YOU!!

She ran to her bedroom locking the door as she cried on her bed.

Makoto: brother, please...*sobs* I want my brother back!!

Back with Sae who is now in tears as she looks at the mirror and sees the hand mark on her right cheek. It stings but her heart is damaged more than a slap to the face.

Sae: why do I have to make the mistake that cost me....I should never did this. But it's too late now my sister hates me. I should deserve her hate.

Y/n: looks like you told her the truth about our past.

Sae: Y/n!!

Y/n: no, you don't deserve to call me by my real name, only Kirito. This is what you get, the past will haunt you. Remember what father said before he died?

Sae: "Never Harm a Niijima"

Y/n: and now you failed. This is what you get from the pain.

Then he vanished leaving Sae alone in tears. She cried until she became tired and slept for the night.

(Timeskip)(Early Morning)

Makoto arrived at the gate early as she sees her friends arrived.

Ryuji: hey Makoto!!

Makoto: hey...

Ren: what's wrong?

Makoto: we should talk about after school.

Ann: are you okay? Anything wrong?

Makoto: I'm fine just something I need to remember some homework.

Ren: okay just tell us once school is done.

Makoto:*mind* why isn't Y/n at school?

Female Student: did you heard the news?

Male Student: yeah Shido and those who sinned were killed by 17 year old. He's also the same person that defeated/killed The Laughing Coffin.

Makoto:!!!

Female Student: yeah that really shocked me how a 17 year old killed the deadliest group.

Makoto: he stopped them!? After that he vanished with his friends both IRL and the Virtual games!!

(After School)(Café Leblanc)

Ren: okay Makoto what's wrong?

Ryuji: yeah you seem strange not able to talk about your sister being scared, what's wrong?

Makoto: Kirito isn't his real name, Y/n is his actual name and he's my brother.

Ann: wait he's your brother!?

Ryuji: then why your sister was getting scared!?

Makoto: she blamed my brother because the death of our father. She began to abused, neglected and abandoned him calling him a burden.

Them: WHAT!?

Futaba: why!? That's wrong!!

Zack and Shiro: hey.

Makoto: okay but what's wrong with Y/n?

Sachi: ever since he told us about his past, he gotten more threatening. He would beat down his enemies in brutal ways. He would sometimes barely talk to myself and his wives and our daughters. Eugeo tried to reason with him but Y/n told him that Sae would feel the same pain. He's 50% towards his goal, after that Sae will commit suicide, taking her soul, making her a pet so she can witness the same pain Y/n went thought. I'm scared about my husband and very worried about your sister Makoto.

Yui: I don't want my daddy to be hurting family!!

Makoto: I......

Ren: Makoto?

Makoto: I don't know what to do now....

Kallen: look I know the truth hurts but if you don't stop my husband he will kill your sister and you'll be alone for a long time!! Please think about your sister!! Think about your father!!!

Makoto:!!!

Then Makoto began to have a flashback.

(Flashback)

Y/n(young): sis?

Makoto(young): yeah?

Y/n(young): will you and big sister promise me to protect me if something is wrong with me?

Makoto(young): why?

Y/n(young): I don't know but I'm scared of myself.

Makoto(young): don't worry we'll protect you no matter what!!

Father(past): kids!! lunch is ready!!

Makoto and Y/n: we're going!!

Makoto: I made a promise, to protect my brother.

Irina: will you do it?

Makoto: to save my siblings!!

Xenovia: good.

Ren: I'll get some supplies for tomorrow

Ryuji: I'll help!!

Everyone agreed and rest for tonight. Makoto stayed with Sachi as she worries about Y/n.

(Thursday)(April 3)

Makoto called Everyone even The Investigation Team and S.E.E.S arrived to the apartment's door and went inside to see the room in a huge mess. Couches in slices, the table broken into pieces, a bit of blood marks.

Ryuji: holy...

Youske: fucking..

Ren: come on we need to find her and Y/n!!

Y/n:*giggles* that will be different from now on.

Makoto: brother!!

Y/n: finally she told you about our past. You still see her as a sister?

Makoto: I made a promise to protect you!!

Y/n: you got yourself a deal, but we're not be doing it here. I have friends who helped me achieve one of my powers.

Yu: wait what?!

All of them teleported to an abandoned building.

Y/n: well here we are.

Futaba: umm why here?

Y/n: like I said: I have friends who helped me control one of my powers.

????: hey Y/n haven't seen you!!

(Ichigo is just with them for Training)

Y/n: Makoto, everyone these guys are the Visored. Soul Reapers who acquired Hollow powers.

Minato: Hollow powers?

Ichigo: let me guess your own hollow is acting up again.

Y/n: well mostly my emotions.

Shinji: well they should be ready for your hollow.

Akechi: hollow?

Shinji: that you have to experience that for yourselves. Nighty night everyone....

Then the screen went to black....
