Description
Masami Saotome is a student at Shinyo Academy who initially appears to be a normal, well-liked teenager but conceals a deeply disturbed inner world. Beneath his composed and charismatic exterior, he harbors an intense hatred for all living things, including himself. He describes himself as an "indirect suicide fetishist," meaning he is driven by a subconscious, powerful desire to be killed by something stronger than him. Each time he narrowly escapes death, he reacts with disappointment rather than relief.

His motivations are rooted in this longing for annihilation, which shapes nearly every decision he makes. He forms an alliance with the Manticore, a synthetic life form created by the Towa Organization, not out of loyalty but because he sees her as a means to fulfill his death wish. Together, they engineer a series of murders and disappearances at the school, with Masami using his charm and intelligence to cover their tracks. He views the Manticore as a superior being and refers to her as his "goddess," yet his relationship with her is ultimately one of mutual exploitation. He is cold, calculating, and emotionally detached, seeing others merely as tools or obstacles.

Masami plays a central role in the tragedy that unfolds at Shinyo Academy. He helps the Manticore hunt and kill students, and he sets a trap for the alien entity Echoes and the investigator Nagi Kirima. During the climax of the events that precede the series, Masami poisons Echoes and kills Nagi Kirima, who did not expect a human accomplice. When Boogiepop intervenes and the Manticore is destroyed by Echoes' light, Masami chooses to end his own life by flying into the pillar of light, finally achieving the destruction he sought.

Key relationships include his partnership with the Manticore, whom he treats with a kind of twisted reverence; his manipulation of classmates; and his brief, deceptive confession of love to Nagi Kirima, which was actually another attempt to be killed by someone strong. In terms of development, Masami begins as a seemingly ordinary student and fully embraces his nihilistic and violent nature once the Manticore gives him purpose. He never seeks redemption; instead, he follows his morbid fascination to its violent conclusion.

Notable abilities include exceptional intellectual cunning, social manipulation, and the ability to present a flawless normal facade while committing horrific acts. He has no supernatural powers, which contrasts with the more fantastical threats in the story and emphasizes his danger as a human being who consciously chooses evil.
