About this title

Synopsis

High school girl, Kanzaki Mitsuki, just got a new older brother when her mother remarries a fellow divorcée with a son. Soon after, her new step dad gets transferred overseas and her mother follows him there, leaving Mitsuki alone with her new step brother, Yuuya. Feeling abandoned by her mother, she stays distant from Yuuya, never really getting along very well with him nor even keeping a conversation with him. However, one day, Mitsuki gets visited by an angel/ghost named Hiyori who takes over her body and tries to make sexual advancements towards Yuuya. Hiyori is the lost spirit of a girl who died but can't reach the gates of heaven and reach eternal peace. To reach heaven, Hiyori puts a belt on Mitsuki called the TST that fills up every time Mitsuki feels sexual feelings from Yuuya, whether it be from going on a date, kissing or even sex. For every time it fills up, Hiyori gains a step on a bridge that connects her current situation and the literal gates of heaven. If she wants to get rid of the annoying Hiyori, Mitsuki has to make some bold and sexy moves against her own brother, even if he is just a step brother. (Source: MangaHelpers)

Birthday: December 21 Mitsuki appears to be a reserved and calm 15 year old girl who recently moved in Yuuya's house after their divorced parents got married again. She encountered and was possessed by an angel one day on her way home from school shortly after transferring, whom the angel holds affection for Mitsuki's older brother. As a result, she often alters between her normal self and the angel's personality around people, especially to get Yuuya's attention. A Chastity belt had been tied onto her with a magical love gauge measuring Kotobuki Hiyori's content on her love and sexual life. The gauge fills up every time Kotobuki Hiyori is satisfied (e.g. after having sex with Mitsuki), but goes down slowly over time when Kotobuki Hiyori's love life is neglected. The belt also brings inconvenience to Mitsuki Kanzaki, especially during urinating. The belt can be released for 3 minutes for relieving purposes but locks itself back after the 3 minutes and can only be opened again after an hour.

An angel/ghost who takes over Mitsuki's body and tries to make sexual advancements towards Yuuya. Hiyori is the lost spirit of a girl who died but can’t reach the gates of heaven and reach eternal peace. It is suggested that in order for her to cross over she has to first reach the gates of heaven by building a series of steps that where made from the satisfaction fluids that accumulate in Mitsuki's heart shaped gauge on her "Chastity Belt." In order for the gauge to fill up she either has to do some lovey-dovey things to Yuuya while inside Mitsuki's body or do some perverted things on Mitsuki's body.

External profile
Mitsuki's step brother. He is a caring stepbrother despite having just met her stepsister. He constantly asked if Mitsuki was facing any trouble when she started acting weirdly. Being the male main character in the show, he is the only one of the 3 main character who had not performed any sexual act or made lewd advances. He had however accidentally been seen naked by his step-sister once in the shower when his step-sister opened the spoiled bathroom lock from the outside. He is however the most sane main character in the show.
