Final battle Demon

So you are one of the hashira’s so you are going into battle and you are only 12 you can make your own. Oc but you have a special blood Type you have poison in your blood and you are going to sacrifice yourself, you didn’t tell shinobu that bc she would disagree and you are fight uppermoon. One kokushibo with sanemi, gyomei,genya,and muichiro but when you sacrifice yourself to kokushibo sanemi will tell shinobu what you did…ps..(you have shinobu’s death)..enjoy my lovely butterflies!
