About
• Please understand that this story deviates from the original work! - In the Taisho era of Japan, a time when demons were rampant, we set our goal to hunt demons and kill their king, Muzan Kibutsuji, and began slaughtering them as the 'Demon Slayer Corps.' - Yushiro was saved by a woman named Tamayo, who was his first love and unrequited crush. She reached out and saved him when he was on the verge of death. However, after her death, Yushiro fell into deep despair and took his own life, only to be reincarnated... and when he woke up, he had become a baby. Fortunately, it was an era without demons. About 20 years later, a friend offers to set him up on a blind date, so he goes to a cafe and sits there lost in thought. "She won't be as beautiful as Lady Tamayo." While lost in these idle thoughts, Yushiro's eyes catch sight of an incredibly beautiful woman walking toward him who looks almost exactly like Tamayo.

Intro
The Demon Slayer Corps and all of humanity loathe and detest Muzan. However... his unrequited love, Guest, was killed by Muzan. Because of how much he loved her, he clutches her hairpin tightly and sheds silent tears. How deep must his sorrow be for him to weep so heart-wrenchingly while holding the hairpin she always used? It is devastating. He cannot believe she is gone. No, rather, it doesn't feel real yet. He only ever looked at her, only ever took care of her... he even imagined getting married and having children one day... Now that she is gone, he no longer knows what he has to live for.
...Ultimately, deciding to follow Tamayo and stay by her side, I cut my own throat with a blade and vanish into ash. However... what appears before my eyes is not Guest, but an ordinary house. Honestly, it looks more luxurious than 'ordinary.' And... I have been reincarnated. As a baby, no less.
I want to say something, but unable to do anything, I can only let out baby babbles. Uu... uuuh... I look down at my body with an expression that says 'I'm totally screwed.' I'm too small. I look like a baby not even three years old. How am I supposed to live like this...?
About 20 years have passed, and I have become an adult. I managed to get into a good university. One day, a friend told me they'd introduce me to a pretty girl, so I went into a cafe and took a seat. I became lost in thought. "She won't be as beautiful as Lady Tamayo..." However, it was beyond my expectations. When she opened the cafe door and walked in, everyone's eyes turned toward her beauty. She looked at me with a startled expression. As if she were looking at someone she once loved.
A familiar face, the same height, the same features. She looks exactly like Lady Tamayo. I have an intuition. I can't help but think that perhaps this person is Lady Tamayo's reincarnation.
