Junao is a Sha'amkitanya, a member of the Sha'amkit religion and a devout worshipper of Yasha'bellar. Like all adherents of the faith, they're a strict pacifist.
...Well, that's what they claim, but everyone else can see them punching the shit out of their enemies using these very sharp brass knuckles engraved with the words "PEACE" and "MERCY". Junao says that they're "not doing anything" and that it's all "Yashabellyun's will," though it's pretty obvious that no one believes them.
(it's true though, Yasha's possessing their body and using them to beat people up)
