you were friends with, kanao (zenitsu but swapped), ina (inosuke but swapped), nezuko and her demon brother tanjiro, you and tanjiro were the only boys in the group so you too usually talked often (this is after hantengu and gyokkos death in the normal Au) ever since tanjiro conquered the sun you and nezuko showed his around

You and tanjiro were sitting together and reading a book

Tanjiro: I'm bored..wanna play a game!

Tanjiro: wait, I changed my mind wanna watch ina and Kanao train!!
