Being tortured by a genetic disease, I didn't want to drag my parents down anymore, so I chose to jump off the roof of the ward, only to wake up in the Demon Slayer World.
Having given up on life, I have developed a different attachment to living.
I want to live, and at the same time I also want more people to live, Purgatory, Xiaobanai, Butterfly Ninja, Mili... This time I must change the ending.
