Megumi Fushiguro

A green debuffer built around stacking "夜" (Green) Damage Received on enemies, so his ceiling shows up specifically inside green-focused teams rather than as a universal support.

S2 (The Well's Unknown Abyss) is the core of his kit. Unlike older green debuffers, it lands BOTH Taijutsu and Jujutsu Green DMG Received at once on the target, and because that debuff chains with his ULT and gets refreshed by S1, the same stat-down can be pushed all the way up to roughly 150% on a target. That single-skill double debuff plus chaining is what defines him.

He effectively replaces Geto as the green stat-debuff anchor. Geto falls behind precisely because he only debuffs Taijutsu OR Jujutsu rather than both, and he doesn't carry that debuff into his ultimate the way this Megumi does — so where Geto caps out, Megumi keeps stacking.

S3 (Max Elephant) is the support layer: AoE Crit RES Down and Green Damage Received Up on every enemy, while handing the ally directly behind him in formation a crit rate, Taijutsu and Jujutsu package. Position your green DPS right behind him so that buff lands on the right unit.

ULT (Shikigami Combo) is his payoff turn — a hard-hitting AoE that layers another wave of Green Taijutsu/Jujutsu DMG taken, Break DMG taken and Crit RES Down on the whole wave, continuing the debuff chain started by S2 while refunding his own energy efficiency for the following turns.

S1 is utility, not a damage button — its job is extending the duration of the green DMG-taken debuffs already on the target, keeping the stacked stat-down alive without re-applying everything. The 3-turn cooldown means you weave it in, not spam it.

His value lives entirely in the debuffs — his own damage falls behind. He could have been stronger, but right now there's no real alternative for the role, so he's worth running regardless. Just be aware that a future green debuffer with more damage attached wouldn't have a hard time powercreeping him.

Rotation: refresh S3 every 4 turns to keep your DPS buffed (its crit/Taijutsu/Jujutsu buffs last exactly 4 turns), and spend the turns in between on S2 to keep the stat debuffs flowing onto the target. Fire ULT during the burst window to extend the chain, and fall back on S1 when you're running short on Cursed Energy — it costs nothing and still keeps the debuff timers alive.
