За съжаление battle chasers не е манга, а американски комикс затова не мога да приема номинацията ти

She is Shirō's Servant, an agile but powerful warrior. Loyal, independent, and reserved, Saber acts coldly but is actually suppressing her emotions to focus on her goals. Her class is considered the "Most Outstanding", with excellent ratings in all categories. Since her Master cannot effectively provide her with Mana, she minimizes her activity to preserve what she has. Saber is frustrated by Shirō's "protective" tendencies, believing his erratic and reckless behavior will jeopardize her chances of winning the Holy Grail War.

A unique Persocon that Motosuwa Hideki finds in the trash outside of a shop, Chii is a Persocon functioning without an OS. Her memory is completely blank and other Persocons that try to find her OS crash. This hints at the idea that she is one of the legendary Chobits. She posseses an ability to learn (much to Hideki's embarassment most of the time, being a slightly perverted male). This capability is demonstrated particularly in her language skills. Up to Chapter 5 she doesn't say anything besides "chii", yet we later learn that she seems able to retain a lot of information through miscellaneous observations but doesn't have any clue on the practical side of things (such as underwear which she first tries on as a hat ). A very cute and innocent character to say the least, she quickly grows an astonishing personality and awareness throughout the manga.
