DB Yamaguchi is a non-player character from Shin Megami Tensei IMAGINE.



Shin Megami Tensei IMAGINE[]

DB Yamaguchi is a Devil Buster first encountered in Third Home. Yamaguchi is Law-aligned, and is most likely a member of the Order of Messiah.

When later encountered in Nakano, siding with DB Yamaguchi over DB Kano can shift the player's alignment to Law.

DB Yamaguichi shows a refusal to kill or harm Divines, though his partner Principality does not seem to care he still prefers to avoid them. This action would be from the fact that demons don't like the killing of their own kind in general even if the enemy attacked the DB or demon first.

His demonic companion is a Principality.


  • The surname Yamaguchi means "mountain, hill" (山) (yama) and "mouth, entrance" (口) (kuchi/guchi).
