Yuuwaku

Suzuki Asato lost his parents at a young age but was taken in by the wealthy Kashima family following a chance encounter. There he met Aoi, a girl one year his senior. Although they spent several years together, the bond between Asato and Aoi was something different—it wasn't quite the relationship of a stepsister and stepbrother. Upon entering high school, Asato moved out of the Kashima residence to live on his own, but one day, he received an email from Aoi summoning him back to the house. This was not the first time Aoi had called him back. In the past, she would occasionally summon him to perform detective-like tasks, such as investigating targets or taking candid photos. Asato received payment for these jobs, but money was never his primary motivation; he acted out of a desire to be of help to Aoi. He assumed this would be another routine investigation, but this assignment differed from the usual: he was told he would have to take direct action against the target. Feeling no guilt whatsoever, Asato carried out the task—all for Aoi's sake.
