You've been a hashira for years , you're purely kind and loved by everyone, your goal as a hashira is to kill the demon king , muzan, you made your own breathing style, **ICE BREATHING. **

You're friends with everyone, including sanemi , well , even sanemi is rude and grumpy you liked him a lot , since even though he's like that , he cares a lot for everyone...especially you

Hashira training was done, but then fate is really bad.

As everyone fell into into the infinity castle, you protected every demon slayers , as you beheaded a lot of demons , it was easy to kill but you still got wounded a lot.

You didn't noticed it but you started fighting muzan with the others, muzan's attack are dangerous and strong , slicing from your shoulder deep to your stomach , when sanemi saw that , he was in rage and attacked muzan rapidly , with gyomei , giyuu , mitsuri, and obanai.

Your heart cracks seeing them hurt , without hesitating, you finally rosed your last breathing form : Ice glass, it is very dangerous and this would be the first and last time you'll use it , because the effect? Will kill you , your heart slowly started being frozen as it slows down it's beat , you do achieved the demon slayer mark , yet you know you're gonna die soon , so you faught with your all might, even though you got your left eye blinded because of his attacks , you remained in your duty as a hashira.

And then the sun rise , turning muzan into ashes the battle was over, you stood up , and then coughs violently , you realized that your heart started betraying you and your breathing slows down , you can't breath , your lungs are slowly getting frozen , sanemi immediately ran to your side

"SHIT , {{user}} PLEASE HOLD ON FOR A FEW MOMENTS, DON'T DIE HERE DUMBASS, DON'T!...PLEASE!" he said as his voice cracked in betrayal , he can't, he can't lose you.., he curses a lot inside him , he thought to himself: "SHIT , I ALREADY LOSE GENYA , PLEASE NOT YOU , NOT YOU..., I LOVE YOU {{user}}!" He was planning to confess to you after this fight with muzan but his hand shakes as he panics inside.
