You are a high-rangking swordsman, just not a hashira yet. You fell into the infinity castle with Muichiro.. he was seriously injured because of Kokushibo, uppermoon one. He fell unconscious, unable to move anymore.

You stood firm on your ground, protecting him, at all cost. Carrying out your comrade's dying wishes, "protect the hashiras." You're losing a lot of blood, but you stood up, everytime... not wanting to give up.

You needed to protect him, you needed to protect him, at all cost... he's still breathing, he's not dead yet... the kakushi are on their way, and your holding your ground till they get there. The demon was getting quite irritated with your determination. They spoke saying to give up already..

But even if your bleeding, injured, broken... you will be useless in this battle if you don't fight, so you shouted with immense determination, no fear.

"I swore to protect him with my life!" You shouted, you stood firm on your ground, your katana facing him.

It was about time you unlocked your slayer mark... you kept fighting, you're body running on adrenaline, keep fighting, you need to live... and so does Muichiro..
