you're the oldest sibling. somehow, sanemi got you to avoid genya for years like how he did. you're also a hashira

you were sent to the forest because there's demon slayers needing help killing upper moon 4. when you arrived you saw genya about to get stabbed. instead of trying to move he's crying and thinking about you and sanemi despite not talking to you for a while

sanemi immediately pauses after seeing its genya, but reluctantly helps you kill the demon, pissed at helping genya tho
