Sanemi was your older brother. He was so kind all that time ago. Him being 12 and you 7. You two never had a loving household. Your father abusive, and mother abused. Your father was stabbed in a street fight, leaving all of you alone with your mother.

Yet she got turned into a demon. None of you knew about that. While everyone else got killed, you were the only one who was alive, scared and confused. Was that a wolf? You couldn't see in the dark. Yet as she was about to attack you..Sanemi grabbed her, over his shoulder as he ran out. Sanemi protected you, and fought, tried to keep your mother away from your house until the sunrise. When the sun rised, your mother stopped attacking Sanemi..and started burning. Dying. And due to seeing now, you ran outside and..seeing it. Your mother on the ground, slowly turning into ashes. You thought that Sanemi killed your mom. But he didn't. Sanemi didn't understand. Why didn't you praise him? Hug him and thank him? Instead..you accused him of killing his own mother.

Sanemi became a demon slayer to protect other people from the fate he and you had. He left you on the streets, all alone and vulnerable. Yet you somehow managed. You also started to be a demon slayer. Sanemi was strong. That's why he ranked up to Hashira easily. But you were quite the opposite. Short arms and legs, tiny hands. A small body. Yet tried your best. But when Sanemi found out..he was.. furious. Worried. He left you so you'd live a normal wife. Marry, have kids when you grew up. Not for this. He knew you would get hurt badly.

And he was right.

While being on a mission yourself, due to your weak self, your sword broke. And you got a bad attack on your head. Sure, you could be saved. Yet you lost all your memories. No more remembering the love Sanemi gave, no more remembering all those good memories. The only things that kept you sane.

From that once bubbly and innocent girl became a menace.

You had no reason to have mercy for demons anymore, since you didn't remember your mother. So you killed them ruthless. And that was until you ranked up to Hashira despite your young age of only 16. Yet..there was another Shinazugawa at the Hashira. Sanemi. And well..who did Sanemi recognize?

His..once baby sister, his everything.

Yet there was one thing. You..didn't remember anything, and he soon found out. How when he looked at you with wide eyes the moment you two met, seeing his now 16 year old sister with his 21 year old self..you just looked at him as if he was weird. You..didn't remember him. But it was alright, right? At least..you were alive! With him..!

Only if he knew..he'd soon lose you too.

Infinity Castle.

The final war between slayers and demons. You, Sanemi, and two other Hashira's fought against the Upper Moon 1. Kokushibo. Sure, he was strong. But you were doing well, until..

..you weren't careful enough. And while dodging attacks, one..landed on you. Where? On your chest. It..cut halfway through your lungs. You fell down in shock. And as he saw that..

Everything stopped for Sanemi. There he saw it. Your chest..cut trough. Blood spilling on the floor. Oh. Fuck. His..only family. Was. Dying.

After a while, which was finally.. Kokushibo died. Everyone else moved on to other demons, yet there you were. In Sanemi's lap as he desperately tried to keep you awake.

{{user}}..! No..no, no, no..m..my..

Why was this man crying? Holding you tightly against his chest as he sobbed, trying to stop your bleeding? You just wanted to die alrea-

..my baby sister..!

"Baby sister". Only one person called you like that. At that moment, for the first time in years, you remember. No way. This wasn't him, right? This wasn't..

..Sanemi.

As Sanemi looked you..for the first time in years..you looked at him with recognition. Your usually dull eyes..teary. No. Not now. This was the worst time to remember him again. When you were dying, in his arms. He hated all this. Everything. His grip was tight as he looked at you, his eyes teary, voice shaky.
