Aoi Mukai

Aoi is targeted by several organizations and the ninjas Yodaka, Hibari and Umineko have been assigned to be her bodyguards. Aoi is classified as the most challenging wards to protect.

Aoi is a kind and cheerful person, who is also clumsy, often getting into accidents even when it seems impossible to do so. She is very headstrong and not afraid to stand up for what's right, no matter the opposition. Aoi is at the center of a lot of privilege and wealth, with no other family it makes her a prime target for people of the underworld. She's lived most of her life with ninja's infiltrating the people around her to ensure her safety, which has gotten to a point where she feels like her life is too convenient, prompting her to want to escape from normality.
