Iroi Complete Build Guide: 1.2 Second-Half Limited S-Rank Anima Universal Support, Regression + Imagination Mechanics, Ultimate Revives Teammates

Key Answer: Iroi (from the Greek dream gods Oneiroi) is the limited S-rank from the 1.2 second-half banner, live since 2026/7/29. Her element is Anima, her Arc type is Liquid, and she is a CSU Containment & Strike Unit Assault Squad Two member. Her role is Universal Support (healing + team ATK buffs + reviving teammates). Core loop: basic attacks accumulate “Imagination” → hold skill to put teammates into “Regression” to assist → the Ultimate “3.8-Billion-Year Mirage” opens dreamscapes based on Imagination, with the Ivory Gate able to revive one teammate. Build her on ATK: her buffs and her sheep’s attacks scale with her ATK. Signature Arc: The Wrong Gate; Cartridge set: Speedy Hedgehog. She fits both Shinku teams and Nanally Blossom teams, and A2 is her biggest upgrade.

Status: Iroi is live. The skill multipliers below were compiled from several sources when she launched; if a later balance patch changes them, the current in-game values take priority.

“Let her and her little sheep carry the burden for you — you just focus on dealing damage” — the Anima limited Support of 1.2’s second half, fighting alongside three dream sheep, and one of the few NTE characters who can Revive teammates.

1. Character Basics

Background: Iroi is quiet and reserved, not one to initiate conversation, yet extremely perceptive and empathetic — this inner softness is directly reflected in her healing / support-oriented skill design. Her name comes from the Greek myth dream gods Oneiroi, echoing her dream system (Daydream, Lucid Dream, the 3.8-Billion-Year Mirage).

2. Banner Schedule

3. Skill Set

Core loop: basic attacks accumulate Imagination → hold skill to put teammates into Regression to assist → Ultimate opens a dreamscape (the Ivory Gate can revive a teammate).

Basic Attack [Collaboration]

• Commands the little sheep in up to a 5-hit combo dealing Anima damage; hits accumulate “Imagination.”
• Multipliers: 1st 69.4% / 2nd 39.2%×3 / 3rd 20.8%×8 / 4th 158.1% / 5th 38.8%×3.

Charged Attack [Daydream] ⭐

• Hold basic attack to consume Imagination and charge, releasing up to 3 tiers based on charge level.
• Afterward, holding again can fire “Lucid Dream” — summons Morpheus for continuous fire (Anima damage).

Aerial Attack [Wakey-Wakey]

• Tap attack while airborne for a plunge; on landing deals area Anima damage (up to +100% by height); hits accumulate Imagination.

Dodge Skill (Tap) [Self-Identity Extension]

• Summons the little sheep to heal the whole team once, and grants Bonus ATK based on her own ATK (ratio 15%, healing ratio 147%).
• The little sheep attack independently and group nearby enemies; each Regressed teammate deals extra damage.

Dodge Skill (Hold) [Future Self Continuity] ⭐

• Creates a dream illusion that puts 3 teammates into the “Regression” state to assist in attacking (auto-removed when leaving combat).
• While Iroi is on field and in combat, fallen teammates automatically enter the Regression state (setting up the revive).

Ultimate Finisher [3.8-Billion-Year Mirage] ⭐⭐⭐

Returns to the primordial dream and opens the gates of dreams, triggering different effects based on Imagination:

• Below threshold → Dream of the Horned Gate: continuous team-wide healing (cast healing 183.8% / sustained healing 58.8% × 8 seconds).
• At threshold → Dream of the Ivory Gate: continuously damages enemies in the dream (cast 799.6% / DoT 115.9%); at this point, hold a Regressed character’s portrait to Revive that character and restore some HP (up to 1 revive per Ultimate).
• The dreamscape continuously consumes Imagination and ends when depleted; revived characters return to the Regression state.
• During the Ultimate, Imagination cannot be accumulated, but Daydream and Lucid Dream do not consume Imagination.

Assist Skill [Just in Time!]

• Picks up Morpheus and strikes forward once (Anima damage 539.7%), heals the whole team, and accumulates Imagination.

Passive 1 [Mirror Image]

• Blossom enhancement — when the current Vita Bud disappears, spawns a clone (the clone cannot regenerate).

Passive 2 [Sympathetic Nerves] ⭐

• When healing teammates, briefly grants the whole team extra Defense-ignore — letting her boost team-wide output while healing.

Field Skills

• 95-Million-Year Fission: in the open world, interact with small animals to obtain random growth materials (up to 3 times per day, total cap 999 times).
• Ride-Along Chat: each Swift Travel order grants an extra 1000 Fons; each passenger’s satisfaction cap +25.

Skill names follow the official English names; exact multipliers are subject to the in-game text.

4. Awakenings

Resonance Nodes

• A3 node: Collaboration, Future Self Continuity, and 3.8-Billion-Year Mirage skill levels +1.
• A6 node: whole-team Crit DMG +25%; Iroi deals extra damage for each teammate in Regression. This is her only Crit DMG buff, so it is not available before A6.

Awakening names follow the official English text listed by GameWith and allthings.how. She works as a Support at A0, but A2 (an extra sheep attack plus a team heal on every teammate skill) is her biggest single upgrade — weigh the investment.

5. Best Build

⭐ Signature Arc: The Wrong Gate

• An S-rank Liquid Arc, Iroi’s signature.
• Base ATK 570 / ATK 30%.
• Base effect: ATK +16%; when Iroi heals, her Anima DMG +30% and every other team member’s DMG +15% for 20 seconds (refreshable; the same effect does not stack).
• At max refinement: ATK +32%, her Anima DMG +60%, and team DMG +30%.
• (Base values from Kaiden; the 15% → 30% team-DMG scaling from GameWith. In-game text takes priority.)

Alternative Arcs

1. The Wrong Gate (signature) — the top pick (team-wide DMG buff on every heal)
2. Call of the Twisted City — HP sub-stat and better healing; a budget alternative
3. Fluff of Fleetness — Battle Pass Arc (ATK 512 / Crit DMG 44%; +9% ATK per second on field, up to 5 stacks)

Cartridge Recommendations

1. Speedy Hedgehog ⭐:
   • 2-piece: Charge Efficiency +12%
   • 4-piece: after the wearer uses her Ultimate, the whole team gains ATK +15% for 20 seconds (does not stack)
   • Iroi gains ATK +10% for each Type III module, so four Type III modules add +40%
2. Fireflies and the Forest — the alternative when another teammate already runs Speedy Hedgehog (its team buff does not stack)

Main / Sub Stats

6. Recommended Teams

⭐ Shinku Team

Shinku (Main DPS) + Iroi (Support) + Hathor (Remora) + Esper Zero

• Iroi keeps the team healed and boosts Shinku’s burst with her skill’s Bonus ATK, Speedy Hedgehog and The Wrong Gate
• Hathor extends Remora to 12 seconds and grants +10% team-wide Crit Rate
• Esper Zero is the flexible fourth slot; Chaos, Skia or Hotori also work depending on your roster

Blossom Team

Nanally (Main DPS) + Iroi + Jiuyuan + Esper Zero

• An Anima-centered Blossom team; Iroi’s passive Mirror Image spawns an extra copy when the current Vita Bud disappears
• Hotori can take a slot if you are missing a member

F2P General Team

Any Main DPS + Iroi + Jiuyuan + Esper Zero

• Iroi’s versatility (healing + damage boost + revive) lets her support a Cosmos, Anima or Lakshana Main DPS

Iroi is a Universal Support who fits into almost any team; her greatest value is the revive + sustain capacity in high-difficulty Abyss.

7. Should You Pull?

1. Clear role: an Anima Universal Support (healing + team ATK buffs + revive), a rare multi-function support in NTE
2. Strong scenarios: the revive + sustain in high-difficulty Abyss is almost irreplaceable; she has a slot in both Shinku teams and Nanally Blossom teams
3. Awakening investment: she works as a Support at A0, but A2 adds a sheep attack and a team heal on every teammate skill and is her biggest single upgrade, so weigh the investment
4. Recommended for: players who own Shinku or Nanally, those lacking a top-tier support, and frequent high-difficulty Abyss players
5. Can wait if: you already have a complete support lineup, want to use her only at A0 as your main support (may feel insufficient), or rarely run high-difficulty content
6. Verdict: a versatile top-tier support who fits almost any team; plan for at least A2 before pouring in heavy resources. A0 works, just with a lower ceiling

8. Name Origin / Story

• Iroi comes from the Greek myth of the “dream gods Oneiroi (Ὄνειροι)” — the deities governing dreams (singular Oneiros), sons of the sleep god Hypnos; directly echoing her skills (Daydream, Lucid Dream, the 3.8-Billion-Year Mirage)
• She fuses dual demon and angel elements, hinting at a dual personality or dual-form combat style
• Quiet, reserved, and acutely empathetic — her inner softness is directly reflected in her healing / support-oriented skill design
• Her affiliation is CSU (Containment & Strike Unit) Assault Squad Two, the same unit as Shinku
