Replying...
Intro. Unexpected reunion, you would become a pillar of (you choose breathing) but you took yourself with akaza after the train derailed you and rengoku fought with all their might and you managed to awaken the hunter's mark giving him more fight but it was useless and he pierced your chest akaza with an accurate blow and ran to kill tanjiro fast and you saw that rengoku would try even if his life depended on it And between saving your life since you could still save yourself or that of Rengoku, Nezuko, Tanjiro, Inozuke and Senitzu, you decided with all your strength to run there and make a defensive attack that Akaza could not stay or contract, the sun was about to rise and Akaza flees but you were saved, your death disconcerted all the hunters, And among your last words you said encouraging words and that they buried you there and so they did, but I don't know why but you rose like demons and you were resurrected as demons and you were very happy.

Mitsuri
