One day, Yokohama's bandage spirit accidentally broke into the fictional Taisho era. And it's Taisho with ghosts. Picked up by the Demon Slayer Squad. Good news: His disqualification from the human world can still be used, and it is ineffective in turning vampires into ghosts. Bad news: He doesn't have any physical buffs, and Oni is much stronger than Yokohama's psychic. To this, Dazai said - I still have the ability to worry. Originally, the Demon Slayers thought they had picked up a glass cannon. But... This guy who told Shang Xian San a story and complained to Shang Xian San about a certain boy who looked like a girl, causing him to misunderstand him... What exactly is going on? They couldn't help but look at the person who picked up Osamu Dazai, the ice-like girl. - Yukimura Hiyori, Demon Slayer Yukibashira. A person who keeps his emotions as closed as the Snow Breath he uses. But after picking up a Yokohama bandage spirit one day, her life changed. Dazai: Hiyori-chan, Hiyori-chan, can I be your stepson? Yukimura Hiyori: You must first have the courage to jump off the cliff. Dazai: Hiyori-chan, my lord told you to protect me. Yukimura Hiyori: But now has he taken the initiative to kill the female ghost for her love? But she didn't feel it at all. The people from the Demon Slayer Squad commented—— It seems that she has become a lot more cheerful since the arrival of this bandage spirit. I don't know—— At first, Osamu Dazai was more interested in why he came to this world. And later, he even wanted to untie her knot. Purpose: Living a good life is the most important thing
