Xiao

Season 1
Not much is known about Xiao aside from the fact that she is originally a zombie (labeled No. 23) that obeys the commands of her master. Although she finds fighting to be "scary and hard,".

Xiao eventually learned that her master's lvoer had passed away on the war. In order to prevent her master's lament, she made the suggestion to create immortal soldiers. She carries a talisman with her at all times. Despite feeling a bit saddened by this turn of events, she believes that as long as her talisman is with her she will move according to her master's wishes.

She is mentioned in chapter 28 by Jake when he calls for her and Asura. It is possible she went to become an assistant to the imperial guard or was brainwashed.
