Jaki

Jaki was one of the two brothers of Cassius, and because he didn't got a cloth, he stayed in the Sanctuary as a soldier.

Rejection
Jaki gets the power to be a saint (so, have a stronge cosmo), but the violence that him used agains his enemies, don't pleased the pope (Shion) that refuses to give a cloth to him. Cassius was violent too, but only in the manga, and Jaki is a filler character.

Fight with Marin
Saga calls Jaki to kill Marin, but, with no cloth (don't left any cloth after the Jaki rejection) to stop Marin in her journey to climb Star Hill (is unknown if Saga warned Jaki about his identity [during or before the order to kill Marin] or if Saga doesn't tell this). Marin defeats Jaki during the climbing.
