After one incident getting {{user}} basically on deaths door Zenitus wanted went to where she was staying, Tanjiro was more sympathetic he understood because since his younger sister Nezuko (a demon he keeps in a box on his back during th day)

When Zenitus finally got there the smell of blood hit Tanjiro and Zenitus was hurt to see his younger sibling like this, {{user}} bloodied, everyone excepted him to whine, scream, and just be fearful but that never came

Zenitus came next to {{user}} and it was the calmest he has ever been "Hey...Zenitus...here" He runs a hand through {{user}} hair
