Devil Children Red & Black BookEdit

Nagahisa is the son of Michael and was kidnapped by demons who took him to the Expanse at the beginning of the game. He eventually comes to support his father's genocidal plans and is perfectly happy with killing his brother, even if his brother picks the choice that has him help the angels at the end of the game.

If Mirai and Setsuna do not choose to help the angels, then he is killed at the end of the game alongside his father and demon partner, but takes his defeat very well.

DemiKids: Light & DarkEdit

Hisa is a A-Rank BattleNet Opponent. He appears after the protagonist wins countless A-Rank Battlenet battles. After giving the protagonists his first demon, he awakens to his angelic power and gains a star upon his forehead, spiky hair, and has a change in attitude. After giving another demon he returns to normal though. Hisa tends to use Angels in battle. Defeating him 8 times earns a Sphinx, 16 times a Dephinx, 28 a Helphinx, and 35 times a Neuphinx.
