Pity Guide: Gacha System Explained
Itsuku is the second featured partner banner in the Forbidden Catalyst Season released alongside Chizuru. Her kit revolves around increasing the base attack stat of the user and buffing the damage of cards that can stack to each other which only Chizuru can do. She can also deal fixed damage passively as long as the wearer can hit 3 or more times per attack card.
However, only pull for Itsuku if you want to use Chizuru at her full power because she is currently the best partner for her even at base manifest ego. Otherwise, other psionic partners can nearly match her power especially if you have high manifest ego on them.
Her performance with other psionic characters is below the other 4-star or even 3-star psionic partners. Two out of three of her passives will not activate with the current lineup for the psionic role and only the increase to base attack will work to other characters that is not Chizuru alongside the unique buff she provides with her ego skill.
Itsuku's banner released on December 3, 2025. She is featured as a rate-up banner for the partner banner alongside Chizuru.
