Masakiyo Ogiwara

From the Megami Tensei wiki

Masakiyo Ogiwara is an antagonist (chaos and law routes only) and potential playable character (neutral route only) in Majin Tensei II: Spiral Nemesis.

Ogiwara is the oldest looking member of the team, with slicked back brown hair. He has a white suit underneath a brown beige coat.

Ogiwara appeared in 1996, shortly after the death of Naoki Takeuchi's father. With his ability to control and speak with demons, he soon gained control of Tokyo. This led to the creation of the military unit Partisan, consisting of Naoki, Kaoru and Tomoharu (later joined by the Tomoharu's sister, Aya), who sought to overthrow Ogiwara and liberate Tokyo.

Despite his human appearance, Ogiwara is not actually human. Rather, he is a being from the world of Amnesia, a paradisaical world. He is said to be a descendent of the fallen angel Lucifer himself. He also comes from the future, where demonic forces from the hellish world of Paranoia will destroy the world in 1996, resulting in the "Slum Tokyo" future of 2024, later replaced by the city of Megalopolis, which Karen Rose calls home. Ogiwara's true goal is to save Tokyo from the destruction (activating HELIOS which "purify" Tokyo from the demonic invasion), regardless of his initial intentions at the start of Majin Tensei II: spiral nemesis.

If Naoki Takeuchi takes the Neutral route, Masakiyo Ogiwara will join the main party He's initially a villain, but if Naoki chooses the neutral path Ogiwara will join the main party as the anti-hero (because he used villainous intentions to conquer Tokyo, that what makes him far from being a traditional hero)
