Hikaru kamiki

He gave Ai Hoshino's address to her stalker, Ryosuke Sugano, hoping for the exact outcome that occurred: her death. He is involved in the murder of Taika Himekawa's mother and is his father. After attempting to kill Ruby and failing to cover up his crimes, Hikaru encounters Acqua, who stages a double murder, resulting in Hikaru's death by falling off a cliff.

He manipulates people, pushing them to commit crimes while remaining in the shadows. He uses his charisma to inspire trust and control his victims. He is a skilled liar—no one ever realized his true nature until Ai Hoshino appeared.

A charismatic yet deeply flawed man, he conceals his true nature behind a mask of charm. A sadistic and possibly insane killer, he enjoys watching the life drain from his victims, claiming it makes him "feel the weight of his own life." A tragic villain, Hikaru's life was constantly marred by abuse, neglect, loneliness, and a desperate need to feel loved. He is a master of lies. No one ever realized his true nature until Ai Hoshino came along.
