Toge Inumaki

A Red Jujutsu attacker who debuffs through his Cursed Speech mechanic: he stacks [Cursed Speech] counts on enemies, and his own attacks deal escalating bonus damage based on how many counts the target has. The whole kit is about building counts and then cashing them in.

S3 is his count-builder — an AoE that applies Cursed Speech to all enemies (extra counts against powerful foes) — so it is the skill you lead with to set up the rest of his damage.

His Ultimate is the payoff: a heavy AoE that deals massive bonus damage scaling with each Cursed Speech count (up to a huge multiplier at max), then consumes those counts. Stacking counts first and then firing the Ultimate is his core damage loop.

S2 is his control and team-support tool: a near-guaranteed Stun, a strong Taijutsu & Jujutsu Damage Received debuff on the target, and a big chunk of Ultimate gauge handed to his allies — so he doubles as a stunner and battery for the team.

The major catch is that almost everything he does sacrifices his own HP (more against powerful enemies), so he is constantly bleeding himself to deal damage. A passive self-heals him each turn, but he is fragile and pairs best with a healer or strong team sustain.

His Ultimate also boosts his Cursed Energy efficiency afterward, easing his energy demands. The standard rotation is to cast S3 a few times to pile up Cursed Speech counts (it applies even more against bosses), then unload the Ultimate for a massive count-fuelled hit — so he is a debuffer-nuker who rewards patient setup and good team sustain.
