Kazuki soon disappears after a tragic bus accident however, and Yuji soon becomes the latest victim of the covert super solider/intelligence agent training program held by international terrorist Heath Oslo, who [Heath] was a family friend of the older Kazumis [Ryoji and Satoko]. As one of Heath's minions in training, Yuji is the subject of various experiments and cruel training procedures designed to make him [Yuji] the perfect soldier.

The excerpt should focus on Soichiro trying to [Soichiro] adjust to his [Soichiro's] new life at First Academy while [Soichiro] also trying to [Soichiro] resolve the damage done to him [Soichiro] when he [Soichiro] was [Soichiro] still Yuji by Ryoji and Satoko and then by Heath after Satoko and Ryoji both [Ryoji and Satoko] committed murder-suicide after Kazuki's disappearance as well as [Soichiro] work out why his [Soichiro's] sisters [Aya, Rio, Koharu, Hiyori, Michika and Miyuki], both adoptive [Aya, Rio, Koharu, Hiyori and Michika] and biological [Miyuki] all [Aya, Rio, Koharu, Hiyori, Michika and Miyuki] have [Aya, Rio, Koharu, Hiyori, Michika and Miyuki] deep feelings for him [Soichiro].
