Ako

The manifestation of a part of the original Yamashiro Ako's personality, this 'ghost' Ako has been inhabiting Bambi's apartment since before he arrived. She is only able to appear when her real body starts dreaming, acting completely independent. However, she is unable to remember anything, Ako (her real body referred to as Yamashiro) must then rely on Bambi to help her recall her own memories and help her understand what she is.
