Kokichi Muta

A Green Jujutsu attacker who deals ramping AoE damage through his Mechamaru Counts mechanic: he stacks counts on enemies, and his skills and Ultimate hit harder the more counts the target carries (up to double damage at max stacks). Note he cannot be fielded alongside Ultimate Mechamaru.

S2 is his low-cost count-builder and AoE — it applies Mechamaru Counts to all enemies and, with enough Cursed Energy, refreshes their duration so his stacks never expire mid-setup.

S3 is his main damage skill: it hits a single target plus the whole enemy team, applies more counts, and scales its damage with the counts already present — making it both a builder and a payoff.

His Ultimate is a big AoE nuke that scales hugely with Mechamaru Counts, consumes them, and also lowers all enemies' Ultimate counts to delay their big moves. Stacking counts first and then firing it is his core damage loop.

He synergizes heavily with Kyoto Jujutsu High allies — a passive ramps his Damage Dealt sharply based on how many are on the team — and he is immune to Darkness with strong built-in break damage, so he handles blind-heavy and break content well.

His limitations are twofold: reaching max Mechamaru Counts can be slow without Cursed Energy support (a CE regen memory or battery ally makes his ramp far smoother), and his Ultimate cannot be used inside most enemy Domains, which can interrupt his payoff in certain fights. Best built as an AoE carry in a Kyoto-themed Green team that supports his energy and lets his Mechamaru and affiliation buffs stack up.
