Future Self Continuity
Press to activate. Summons lambs to heal all team members once and grant them an ATK bonus based on Iroi’s Base ATK.
Summons three lambs to attack respectively, dealing Anima DMG and pulling in nearby enemies.

Hold to activate. Creates dreamlike illusions during battle, causing 3 allies to enter the Regression state and assist in battle. Regression is automatically removed after leaving combat.
While Iroi is on the team and in combat, any ally who falls enters the Regression state. Builds up Imagination when any fallen ally enters the Regression state.
I have to stay awake the night before my birthday. I believe that if I fall asleep, someone will come for the old me and leave a newly grown me in its place.
3.8-Billion-Year Mirage
Return to the first dream. Opens the gate to a dream and triggers different effects based on the amount of Imagination built up.
If Imagination has not reached the required threshold: Iroi opens the Dream of the Horned Gate, continuously healing all allies.
If Imagination has reached the required threshold: Iroi opens the Dream of the Ivory Gate, continuously healing all allies and dealing Anima DMG to enemies inside the dream. During this time, press and hold the avatar of a team member in the Regression state to temporarily revive them and restore a portion of their HP. This effect can revive up to 1 character during each dream.
The dream continuously consumes Imagination. When Imagination is depleted, the dream ends, and the revived character returns to the Regression state.
While the dream is active, Imagination cannot be built up, but casting Daydream and Lucid Dream do not consume Imagination.
I heard the bell at both ends of the dream: once at the beginning, once at the end. But the bell only rang once. From hydrothermal vents in the deep sea to skyscrapers on land, that awful chime has followed everything. Oh my, it's been ringing for 3.8 billion years.
Bang!
Just in time! Picks up Morpheus and strikes forward, dealing 1 instance of Anima DMG, healing all team members, and building up Imagination.
Would you believe me if I said this is the sound of the Big Bang?

Review
Good healing; can keep the whole team healthy with her Redirect, Ult, and swap heal.
Gives team buffs with DEF shred and ATK% boost.
Can group enemies together with her Redirect Skill.
Does decent damage while healing, especially with her Ult.
Has good range and feels smooth to play.
Easy to mess up with her Redirect long-press, which can weaken your team for the whole fight.
Needs to stay on the field a bit to charge her Ult.
Iroi is an Anima support character who can heal you while also providing other forms of support in combat. She builds up a resource called Imagination through her basic attacks, Redirect Skills, support skills and when allies enter the Regression state.
She spends this resource with her Ultimate, 3.8-Billion-Year Mirage, which has different effects depending on how much Imagination she has accumulated. If she hasn't reached the required amount, the Ultimate simply heals all allies. However, if she has enough Imagination, it does more than that: While it still heals allies, it also now deals DMG, and while an ally is in the Regression state, you can press and hold their icon to revive them and restore a portion of their HP.
So, what exactly is Regression? It's a unique state where Iroi turns allies into sheep. While in Regression, allies attack automatically, deal increased DMG based on Iroi's Base ATK, and become essentially invincible. However, it's also easy to trigger accidentally, as holding her Redirect Skill causes three allies to enter Regression. Allies will also enter this state automatically if they are defeated while Iroi is on the team.
Although this may make it seem like Iroi can be played as a DPS by keeping allies in Regression, her sheep won't outdamage actual DPS characters, and you'll lose access to the utility those characters provide.
So then, what does she actually do aside from healing and having this weird sheep mode? As mentioned earlier, her Redirect Skill, Future Self Continuity, builds up Imagination while also granting a Bonus ATK buff to all allies. It also groups up enemies, making it quite helpful in AoE situations. Her passive, Sympathetic Nerves, also grants the team DEF Ignore for a short duration whenever she heals an ally. Her signature Arc is also worth mentioning here, even though we don't normally cover signature Arcs in these reviews, because it grants a DMG buff every time she heals. Thankfully, healing is a core part of her kit, and she can trigger it through her Redirect Skill, Support Skill, and, of course, the Ultimate mentioned earlier. This makes it easy to maintain high uptime on both her passive's DEF Ignore and her signature Arc's DMG buff, making her a much more valuable healer and buffer for your other units than as a DPS herself.
However, she can still deal a good amount of damage through her Blossom Enhancement. After Blossom has been active for 3 seconds, it creates a copy of Vita Bud. This copied Vita Bud will not create another copy when it expires, but it still attacks 20 times, dealing 37.5% of the original Vita Bud's damage. While each hit deals less damage, the large number of attacks does add up. More importantly, the frequent hits also make it much easier to trigger Charge since the copied Vita Bud attacks so much. She can also provide extra damage through her Ultimate, which deals solid AoE damage alongside her main role as a healer and buffer.
Iroi is a quirky support character who will be a great partner for her actual in-lore teammate Shinku, but she will also be able to find spots in any Blossom team and send enemies crawling back into their mommy’s bellies.

Teams & Synergy
Iroi Charge Support
Iroi Blossom
Iroi Main DPS
Iroi is an Anima support and healer that can function as a main DPS in an emergency, or for fun. She doesn’t have a set rotation, since she is mainly a support character. Here’s some information about her kit and how it works so you can better understand how to play her and what to think about when using her on your teams!
When a teammate falls in battle, they automatically turn into a sheep
Using Iroi's Ultimate deals “DoT” damage and drains her Imagination (caps at 12.5 seconds)
This is not technically DoT damage, and instead is a pulse from the character during Iroi’s ultimate duration. As such, it does not contribute to Sakiri’s passive for extra damage dealt from DoT.
Team gets continuous healing while this is active
Her Blossom effect lasts a total of 13 seconds (3 seconds after the base blossom, her copied blossom appears and lasts 10s)
Iroi can heal the entire team from her Redirect Skill, Support Skill, and Ultimate.
Iroi's Hold Skill turns the whole team into sheep
Hold the character’s respective swap button for whichever teammate you want to Unsheep
The Unsheep effect sticks around until Iroi's Imagination runs dry (roughly 12 seconds max)
You're able to Unsheep a teammate even if they've fallen, since all fallen allies become sheep
Sheep seem to inherit Iroi's stats when dealing damage
Iroi can Esper Cycle with sheep, even though she doesn't actually swap off-field, this is based on Iroi’s stats.
Esper Cycling with sheep doesn't pull from the original character's Esper Cycle stat
Only Iroi can Esper Cycle with sheep, unsheeped characters can't do it themselves
Iroi can also Esper Cycle with an Unsheeped character
Character’s reaction passives still work, while they are turned into sheep. Eg. Jiuyuan's double blossom passive will still trigger if you proc a Blossom
Sheepified characters still generate Energy and keep their mechanics active (Hathor Feathers, Hotori's time energy, etc.)
