Iroi Build Guide

2026-10-16·5 min read

Iroi is a permanent S-Class Anima Esper who fills the Survival role, using Liquid-type Arc compatibility. She's a healer and buffer who turns her team's healing into damage: she steps in, heals everyone, gives the team a DEF Ignore and ATK buff, and steps back out.

Best Arcs

S-rankBIS

The Wrong Gate

Iroi's signature Arc and by far the best option. It gives her 570 base ATK, boosts her Anima DMG, and raises the whole team's damage every time she heals, which turns her healing into a team-wide damage buff.

S-rankALT

The Last Rose

Lacrimosa's signature Arc, useful for Iroi when she's played as a Main DPS. It gives a lot of base ATK and CRIT Rate, but its active effect isn't realistic to keep up, since Iroi has no true DoT.
