Mizaru is a character in killer7. She is a Remnant Psyche of Harman Smith and the ex-wife of fellow Remnant Psyche Iwazaru.
Mizaru is depicted as a woman wearing a dark-red bodysuit, similar to Iwazaru's, but with long lace-up boots; she is always covering her eyes with her right hand in accordance with her name, which roughly translates to 'see no evil'. KAEDE Smith can summon her at certain points during the game by creating a blood shower, whereupon Mizaru will appear, point strangely at an invisible barrier without looking at it, and shatter it before disappearing. Beyond her description in hand in killer7 as 'KAEDE's servant', her personality and background are left completely unexplored.
