Kasumi Miwa

A Green Taijutsu attacker built around her Batto Count: a stacking resource that her skills feed into and that a passive converts into scaling Taijutsu, Ultimate charge, Crit Damage and cheaper skills as it climbs. The whole kit is about building Batto stacks as fast as possible.

Her SP upgrades are what define her — without them she is a fairly underwhelming solo bruiser, but with SP unlocked she transforms into a top-tier Green pick. The huge jump comes from her SP passive and SP Ultimate, so judge her almost entirely on her SP form.

S2 puts her in a Counter State and Simple Domain — once her Batto Count is high enough it upgrades into an AoE that also builds more stacks, so it shifts from a setup tool early to a damage tool later.

S3 is her reliable single-target multi-hit that buffs her own crit and adds Batto stacks, and at high Batto Count it too upgrades to refresh her Counter and Simple Domain — making it strong throughout the fight.

Her Ultimate is a hard single-target hit that taunts the target into attacking her, then her Counter and Batto-building punish them for it; her SP Ultimate hits far harder and adds a big self crit buff.

One of her biggest strengths in her SP form is team support: every time she lands a Critical Hit she grants the whole Green team a large Taijutsu & Jujutsu Stat buff plus a crit rate boost — and since her kit is built to crit constantly, she keeps these team buffs running almost permanently, making her a Green-team enabler rather than a pure solo carry.

Simple Domain gives her Jujutsu damage reduction and nullifies enemy Domain effects, so she doubles as a safety valve against Domain Expansion content. She also scales up alongside other Kyoto Jujutsu High students through a passive that boosts her damage based on how many are on the team.
