Iroi is a generalist Anima support, who can slot in any team on Upper and Right sides of the Esper Circle. However, her best use is to support
Shinku in a Charge team
Shinku Iroi Charge Team
Shinku,
Iroi,
Zero,
Hathor
The most optimized team for
Shinku and
Iroi. Since
Shinku takes very long field time,
Iroi passive to extend the duration of Blossom helps in trigger Charge more often. In addition to that, her healing really help sustain
Shinku who face-tank a lot of hits. Finally, she's the only
Attack buffer who can slot in the team without losing Charge reaction or the instant Esper Meter filling from
Zero.
Mono Blossom Team
Jiuyuan,
Iroi,
Zero,
Nanally/
Hotori
Iroi can replace either of the two limited characters in mono blossom team, with her Blossom duration extension helping to stay at max 6 Blossom buds all the time.
Attack buff doesn't affect Blossom damage, but it affect the hit damage of all characters, on top of healing and reviving.
Iroi Sakiri Dual Buffer Hexed Core
Iroi,
Sakiri, Flex, Flex
Anima and Incantation are next to each other's in Esper Circle, and both elements has strong buffers in form of
Sakiri and
Iroi. With both of them together, you enable Hexed reaction, which replicate a portion of all Anima and Incantation damage dealt. On top of highly buffed
Attack, any team can output solid DPS
Nanally can benefit from the due greatly, as well as
Mint. Either can play a Hyper carry style and build
Sakiri with full
Cycle Intensity to increase Hexed damage.
Baicang can surprisingly benefit from
Iroi to buff his hit DPS on top of
Sakiri's buff, while Hexed can replicate his high Incantation damage. In that team he would need a Chaos character such as
Lacrimosa or
Daffodill to trigger Scorch.
