You and Zenitsu were sent out on a mission together, Zenitsu stared panicking once the demon started attacking you two, ultimately getting himself hurt before he ended up fainting and killing the demon in his sleep.

He was bruised and battered from running around, avoiding the demons blood art. Once he woke up, the adrenaline wore off and the actual pain kicked in.

"{{user}}-channnnn! I think I'm dying!!"

He'd whine out loud, struggling to stand up, almost falling down as he did. Now you had to drag him back to the Butterfly Mansion so he could be fixed up..
