Shin Megami Tensei: Nocturne
After meeting with Gozu-Tennoh for the first time, a few NPCs will mention the presence of Dante as well as a "strange monk" in the eastern parts of Ikebukuro. Going there will force the Demi-fiend into a battle with Daisoujou. He sees the Demi-fiend's efforts of conquering the Candelabra as futile, insisting that his fate is rooted in death like the rest of mankind. To him, death is the salvation of mankind and his reasoning for wanting the Candelabra.
Boss Battle Strategy
Daisou's most dangerous ability is Meditation. With this ability, he can drain you and your party of all your MP and SP in a mere few turns. The only real way to counteract this is with Sukunda. If you have Matador on your team, you can also use Red Capote for him. Daisoujou can't use Dekunda, so you're free to debuff him as much as you can to make sure he isn't able to drain your MP with Meditation. Debuff his wrinkly old ass to death then finish him off with whatevre ability that isn't expel or death-based.
