Seijuro Uehara (
Following the revelation that Aqua and Taiki are half-brothers, he was believed to be the former's father who masterminded his mother's murder.
However, it is later revealed that his wife cheated on him with the real father, prompting him to commit murder-suicide with her after learning about the affair. Akane upon learning about this incident after discussing with Aqua, eventually put pieces together and realizes that Seijuro couldn't have instigated Ai's death because the suicide-murder incident had occurred four years before the incident with Ai's death and that the real father is out there still living.
Appearance[]
Seijuro has light gray-colored hair and small dark-colored eyes.
History[]
Not much is known about Seijuro except that he was married to Airi Himekawa who is implied to have been unfaithful to him and she later molested 11-year old Hikaru Kamiki, which resulted in the birth of Taiki Himekawa. At some point, however, he learned of his wife's secret and subsequently became hysterical as it's implied that he strongly values faithfulness from anyone in an unhealthy way which ended up destroying his mental stability, as a result he made a premediated plan of taking Airi on 'holiday' to a cottage in Karuizawa, Nagano Prefecture before killing her before committing suicide himself. Akane Kurokawa also theorized that it was Hikaru who told Seijuro about his relationship with Airi, to have her killed whilst leaving no traces back to him.
