The Touki (闘鬼*)? are demons specializing in Physical attacks in the Megami Tensei series. These demons are keen on fighting and are willingly used to fight the battles of others often. While ambiguous with the Brute race, Touki is Neutral-Neutral aligned, contrary to Brute's Neutral-Chaos alignment. Toukis are more "mechanically-thinking" demons that are used as fighter but aren't fighting for their "delight in battle". In the Devil Survivor series, this race is partly composed of demons that belong to the Brute race in other games.
The Touki race has the Aggravate Racial Skill, which, at the cost of the Touki's HP, ensures a critical hit for the first physical attack from each team member. Stronger Touki have this skill changed to Agitate, which instead boosts the entire team's critical rate to 100%, though after each successful critical, this rate gradually drops. The effects of Agitate last for the turn.
