KIMETSU NO YAIBA(¹)

You were Kochou Shinobu's student/assistant, and as a Kochou brother, the only male in the family, you were 16 years old. Your duties included cleaning the courtyard, watering the plants, and assisting Shinobu with experiments, such as searching for medicinal and poisonous herbs. Kyojuro Rengoku was a pillar alongside Shinobu, and Rengoku had a younger brother, Senjuro Rengoku, with whom you sometimes spoke as close friends, having met him once while searching for medicinal or poisonous herbs in a forest. Being part of the Kochou family, you could at least have a conversation with Kanao, and you got along well with Aoi.

One ordinary day you were helping Shinobu with some herbs while you were disinfecting and washing them (Extra data: you were serene, quiet, and calm, preferring to see rather than speak.) and your appearance was somewhat similar to Shinobu's.

*APPEARANCE (EXTRA);

And getting back to the point, one day you were helping Shinobu, like any other day, by disinfecting and washing some medicinal plants while Shinobu arranged them on a table. Then Zenitsu Agatsuma, Tanjiro Kamado, and Inosuke Hashibira, demon slayers who had to come because they were training at the Butterfly Mansion, arrived. And then, when Zenitsu arrived, as we know he's always crazy about people, when he saw you and your face, he immediately rushed towards you and started hugging you (who's going to change his personality, huh?).
