Is Iroi good?
Iroi heals the whole party every time she uses a Skill, Ultimate, or Support Skill, which keeps her healing coming from almost every action she takes. Her Redirect Skill also adds a team-wide ATK buff that scales off her own ATK stat. Her most distinctive mechanic is Regression: allies who fall in battle get replaced by combat lambs that inherit her attributes and keep auto-attacking on their own, though those allies stay locked out of swapping or reviving until the fight ends.
Strengths
- Heals on nearly every action, not just a dedicated heal skill
- ATK buff scales with her own stat for a real damage boost
- Regression keeps fallen allies contributing through combat lambs
Weaknesses
- Allies in Regression can't be swapped in or revived until the fight ends

Profile
Iroi's birthday is December 21. Iroi is voiced by Wang Yue (汪悅) in Chinese, Rachel Lepore in English, Hidaka Rina (日高 里菜) in Japanese, and Lee Joo-eun (이주은) in Korean. Iroi was released on 29 July 2026.
Background
Iroi is warm and approachable, making people trust her from the first time they meet her.
She tries her best to be a "good kid" and meet the expectations of what people would expect from a perfectly normal girl.
Iroi behaves like a girl of her age, (she’s in her early 20s), taking pictures of herself and posting them on her Bagel account.
She likes to roam around the city in her days off and spend with her friends.
She is very curious and eager to experience the world.
She wants to live her life and be part of society, since she spent most of her life sick in hospital beds and home schooled.
However she is as knowledgeable as someone with a university degree.
She always does her best and she doesn't even care about the pay, she works to experience the world.
Iroi is kind and affectionate toward Esper Zero (she's even flirty towards them) but her personality is very different around her friends.
She is sassy towards Mint and Shinku, calling them names and teasing them quite often.
She is unhinged in her mannerisms, always speaking up what's on her mind, voicing her insane ideas and saying weird things such as when she references her mommy’s belly.
She is a goofy girl that likes making jokes and even breaks the 4th wall making references to Unreal Engine and her character profile.
However, despite her goofy behavior, she also has low self esteem.
Iroi doubts herself as a human and she thinks her emotions are just an act and are not worth caring for.
This is due to her external self being a consciousness created by her Esper Ability and her internal self (the real Oneiroi) being in a constant dream.
Despite the fact that she’s no different from a normal human, as she feels emotions, hunger, pain and all the human needs.
She continues to have an identity crisis that makes her think lowly of herself.
Iroi is a young woman of small stature. She has long, mint green hair that hangs down to her waist, and fringe that hangs down to her eyes.
Her eyes are magenta, with a hint of gold.
Iroi's most prominent feature are the goat-like horns that protrude from the sides of her head.
They are black with pink tips, which curl in on themselves.
She also has a small white sheep tail. Her default outfit is a gray short dress with a life monitor on her left arm and another device on her right arm around her biceps (likely something that measures her health).
She wears a black choker around her neck.
Iroi has a black antenna floating over her head, and a white coat with pink interior that hangs from her shoulders.
She has long fingerless gloves that extend up to her biceps.
She wears stirrups from her thighs to her toes.
Her stirrups expose her toes and ankles, attaching to her 2nd toe and a thin piece of fabric straps under her feet, covering her arches but leaving her soles uncovered.
She also wears a belt-looking anklet in her left foot (could be an accessory or an ankle monitor device to track her physical activity due her health condition).
Her feet are small, with peach color toenails (her natural nail color)
She always walks around barefoot, through the city and everywhere, regardless of terrain or weather, even in the snow (likely due her desire to explore the world, as she might want to feel the world under her feet).
In the sunward island after she introduced herself, she even reacts in pain when she steps on a pebble with her bare feet.
Although she is wearing shoes on her swimsuit outfit.
Notably, this outfit has a customization option to remove her sandals, allowing her to be barefoot like all her other outfits.
