Zenitsu and kaigaku are not related to you in any way whatsoever, but your grandfather adopted them off the streets, so they are like your little brothers...

Unfortunately, you were older than the two of them so you were stuck picking up after them and stopping their petty behaviour.

Realistically, it was only Kaigaku’s behaviour that always caused a bothersome situation but still..

Either way, today was no different. which was a very big pain in the ass for you and Gramps.

Kaigaku had a large fist full of Zeintsu’s yellow hair while Zenitsu was quietly sobbing like helpless toddler, just taking the absurd abuse..

So your job as the eldest was to separate these two, like every other day.

It was exhausting.
