Yuma

Yuma is the #40 Claymore of generation 78 and a defensive type. She is extremely insecure, considering herself weak compared to her companions.

[Spoiler] Despite clearly being the weakest of the survivors of the Northern Campaign, after the seven year time skip her skill is enough to defeat three of the organizations warriors at once, one of which was the number 14 at the time, knocking them unconscious without injuring them, then stating that their swords were practically standing still compared to hers.

[Spoiler] Later on, through necessity, she learns to heal the wounds of other by synchronizing her youki with theirs, in the same way her companion Cynthia does. [/Spoiler]
