Iroi is the S-Rank Anima healer and buffer who headlines the second phase of Neverness to Everness Version 1.2, “999 Nights.” She is the first premium S-Class support the game has offered, and her kit combines team-wide healing, an in-combat revive, attack buffs, and light crowd control. That mix makes her stand out in a roster where dedicated healers are scarce, and it is the main reason players are weighing whether to spend on her.
Quick answer: Pull Iroi if your account lacks a reliable healer or you want a flexible support that can revive a fallen ally and buff your DPS. Skip her if you already run a strong sustain unit that keeps your teams alive, since her kit overlaps heavily with what a dedicated healer already provides.

What Iroi does in combat
Iroi’s entire kit is built around sustaining a team. Her Esper ability summons three dream-lambs, Phantasos, Morpheus, and Icelos, that create a persistent dream field around her. Her Basic Attack, Collaboration, chains up to five Anima hits while building Imagination, a resource she spends on charged attacks and her ultimate.
Her Redirect skill, Future Self Continuity, is flexible. Tapping it generates more Imagination through the lambs, while holding it puts up to three teammates into Regression, making them briefly invincible and swapping the lambs in to fight for them. That gives Iroi a defensive escape valve most supports do not have.
Her ultimate, the 3.8-Billion-Year Mirage (also called Gates of Dreams), scales with how much Imagination she has banked. Below a threshold, it delivers continuous team-wide healing; above it, it damages all enemies and revives a fallen ally. Being able to revive a playable character while still dealing damage is unique among Version 1.2 units. Her Blossom Cycle Enhancement also spawns a duplicate Vita Bud whenever the first one disappears, which stretches her sustain even further.

When to pull and when to skip
The case for pulling is strongest if your roster is missing a healer. Support and sustain characters tend to hold their value in the meta far longer than damage dealers, so investing in Iroi now is likely to pay off across many patches. She also pairs naturally with Shinku, the Cosmos DPS from Phase 1, and the two are clearly designed to be run together.
The case for skipping comes down to competition. Free S-Class selectors made Sakiri available as a solid support, and she covers buffing and crowd control for many teams. If your survivability is already handled, Iroi’s value drops sharply. High-end teams rarely need an in-combat revive, so her safety net matters most to casual and mid-budget players.

Iroi vs. Sakiri
| Factor | Iroi | Sakiri |
|---|---|---|
| Best teams | Buffer, heal, and CC for Remora and Blossom teams | Buffer and CC for Scorch and Hex teams |
| Healing | Strong healing that makes combat more forgiving | No dedicated healing |
| Flexibility | Highly flexible playstyle across roles | More specialized |
| Cost efficiency | F2P friendly, works well at A0 | Easier to ascend, cheaper for F2P |
Best console sets, stats, and Arcs
Iroi is cheap to build for a support role, and she does not need her signature Arc or any awakenings to perform. Your console set choice depends on whether you lean into buffing, damage, or a balanced profile.
| Console set | Effect | Best for |
|---|---|---|
| Speedy Hedgehog | Epic (2): Charge Efficiency +12%. Legendary (4): +15% ATK to all allies for 20s after Ultimate (no stacking) | Pure support and buffing |
| Fireflies and the Forest | Epic (2): Anima DMG +10%. Legendary (4): +8% CRIT DMG per stack when a nearby enemy takes team Anima DMG, up to 7 stacks | DPS and Anima builds |
| Shadow Creed | Epic (2): ATK +10%. Legendary (4): +25% ATK for 20s after casting a Skill | Balanced ATK and healing |
For console main attributes, prioritize CRIT, ATK, Anima DMG, Cycle Intensity, or Healing depending on the role you want her to play. Her best-in-slot Arc is The Wrong Gate, which raises ATK and boosts both her Anima damage and team-wide damage when she heals. Youthful Fantasy is the strong free-to-play alternative, leaning into Break Intensity and support triggers.

Team compositions
Iroi’s core synergy is with Jiuyuan and Esper Zero (the Main Character), a pairing that maximizes the generation of Vita Buds. From that base, she slots into several established Version 1.2 lineups, and she can even function as a main DPS when built for it.
| Team | Members |
|---|---|
| Hotori Blossom Machine Gun | Iroi, Esper Zero, Hotori, Jiuyuan |
| Shinku Charge Team | Iroi, Esper Zero, Shinku, Jiuyuan |
| Blossom Team | Iroi, Esper Zero, Nanally, Jiuyuan |
| Main DPS Team | Iroi, Hathor, Esper Zero, Jiuyuan |
Awakenings and investment cost
Iroi is fully functional at A0, so you do not need copies to make her work. Her first awakening restores 3 Imagination per second while she is off-field, increases Imagination gain by 30%, and grants her maximum Imagination on entering battle. Her second awakening slot adds a Sympathetic Nerves effect that raises all team members’ ATK by 15% of Iroi’s Base ATK for 20 seconds. A1 and A5 are the notable breakpoints, but neither is required for her to perform.
For a support role, keeping her skills at level 6 is enough, which avoids the need for premium upgrade materials. If you plan to push her to Level 80 with maxed skills and signature Arc, the total investment is substantial, including 2,783,000 Beetle Coin, 86 A Page from Delusion’s Shore, 35 Good Boy Stamp, and 96 Dreamless Seed, among other materials. The Good Boy Stamp is time-gated to weekly bosses, so start collecting early if you intend to fully build her.

Open-world resource farming
Beyond combat, Iroi carries a useful open-world life skill called 95-Million-Year Divide. It lets you interact with small animals to obtain a random growth item, up to three times per day and 999 times in total. The fastest daily routine is to teleport to Hankaku Street and pet the dog next to the street musician three times, which quickly claims those free character growth materials.
Put together, Iroi is a low-investment, high-flexibility support whose healing, revive, and ATK buffs raise the floor of almost any team. If your account needs sustain, she is one of the safer long-term investments in Version 1.2. If your survivability is already covered, you can comfortably pass and hold your resources for a unit that fills a real gap.
