Analysis

Iroi is the limited Anima Support of the 1.2 second half, built as an all-rounder: team healing, ATK buffs, and even reviving teammates (an extremely rare mechanic in the game). Her core is the "Imagination" resource — built by Basic Attack hits and spent by her skill to put teammates into "Regression" so they assist in attacks. Her Ultimate "3.8-Billion-Year Mirage" opens a different dream depending on Imagination, and Dream of the Ivory Gate can revive one fallen teammate. Her buffs and her sheep's attacks scale with ATK, so build her on ATK. Her passive "Sympathetic Nerves" grants the whole team extra DEF ignore when she heals; her only Crit DMG buff comes from the A6 Resonance node (team-wide Crit DMG +25%). Shinku teams and Nanally Blossom teams are her main homes. She works at A0, but A2 (a sheep assist attack and team heal whenever a teammate casts a skill) is her biggest single upgrade.

Profile

Gender: Female

Skills

Skill names follow English wiki naming; in-game names are authoritative.

Basic Attack

Collaboration

Commands her little sheep in up to a 5-hit combo dealing Anima DMG; hits build "Imagination." [Multipliers: 1st 69.4% / 4th 158.1% / 5th 38.8%×3]

Charged Basic

Daydream

Hold Basic Attack to consume Imagination and charge, releasing up to 3 tiers based on charge level. Holding again afterward fires "Lucid Dream," summoning Morpheus for continuous fire.

Aerial Basic

Wakey-Wakey

Press Basic Attack in mid-air to plunge, dealing area Anima DMG on landing (up to +100% based on fall height). Hits build Imagination.

Shift Skill (Tap)

Self-Identity Extension

Summons the little sheep to heal the whole team once and grant Bonus ATK based on Iroi's ATK. The sheep attack independently and pull enemies together; each teammate in Regression deals extra damage.

Shift Skill (Hold)

Future Self Continuity

Creates a dream illusion that puts 3 teammates into the "Regression" state to assist in attacks. The state is removed automatically when combat ends.

EX-Rail Ultimate

3.8-Billion-Year Mirage

Opens a different dream based on Imagination: below the threshold, "Dream of the Horned Gate" (continuous healing); at the threshold, "Dream of the Ivory Gate" (continuous damage, and you can hold a Regressed character's portrait to revive one fallen teammate).

Assist Skill

Just in Time!

Picks up Morpheus and strikes forward once (Anima DMG 539.7%), heals the whole team and builds Imagination.

Passive

Mirror Image

Blossom enhancement: when the current Vita Bud disappears, a copy is created (the copy cannot regenerate).

Passive

Sympathetic Nerves

When Iroi heals teammates, the whole team briefly gains extra DEF ignore.

Awakenings (M1–M6)

Awakening effects cross-checked with English databases; the in-game text is authoritative.

Iterated Prisoner's Dilemma: Iroi slowly regenerates Imagination while off-field.

Strategy: Tit for Tat: When any teammate casts a skill, Iroi randomly summons Morpheus, Icelos or Phantasos for an assist attack (with a cooldown).

Trait: Cooperative: Iroi's healing effect +36%.

Trait: Retaliatory: Raises the attack multipliers of teammates in Regression (each Morpheus / Icelos / Phantasos move gains an ATK multiplier bonus).

Trait: Transparent: Enhances Sympathetic Nerves so it also raises the whole team's ATK by 15% of Iroi's Base ATK for 20 seconds.

Trait: Forgiving: After Iroi casts her Ultimate, a revived character additionally recovers HP, Cycle Energy and Ultimate Energy.

Signature Arc

The Wrong Gate

Base ATK 570 Sub-stat ATK 30%

ATK +16%. When Iroi heals: her own Anima DMG +30% for 20 seconds, and every other team member gains +15% DMG (the same effect does not stack). At max refinement: ATK +32%, her Anima DMG +60%, and team DMG +30%. Iroi's signature Arc. [Base values from Kaiden, refinement scaling from GameWith; in-game text takes priority]

Build Tips

Role: Universal Support (healing + team-wide ATK buffs + revive). Core loop: Basic Attacks and skills build "Imagination," her skill puts teammates into "Regression" to assist in attacks, and her Ultimate opens "Dream of the Ivory Gate" based on Imagination, which can revive one teammate. Build her on ATK: the Bonus ATK she gives the team, her sheep's attacks and her Awakening buffs all scale with Iroi's ATK. Main stats: ATK% > Anima DMG / Healing Bonus; sub-stats: ATK% > flat ATK > Crit Rate / Charge Efficiency; HP and DEF last. Signature Arc: The Wrong Gate (ATK +16%; on heal, her Anima DMG +30% and every other team member's DMG +15%; +32% / +60% / +30% at max refinement). Cartridge: 4-piece Speedy Hedgehog (whole team ATK +15% for 20 seconds after her Ultimate); if another teammate already runs Speedy Hedgehog, use Fireflies and the Forest instead. She fits both Shinku teams and Nanally Blossom teams.
