Introduction

Welcome to Koishi (F1) EX Battle Stage! In this time-limited stage you will be faced against F1 Koishi and the return of S2 Satori in yet another underworld themed locale. The featured Choose an Animal Spirit story card provides wonderful effects — 3 layers of Barrier Recovery to self, 50% Body Bullet UP, and 50% Energy Bullet UP — which a variety of characters who can take advantage of.

To deep dive a bit, units who have both Body and Energy bullets on their spell cards will enjoy this card as they can maximize the use of its effects, not to mention the additional barrier recovery which can prove beneficial in most cases. L1 Kasen Ibaraki and L1 Fujiwara no Mokou's spell cards are just among the few examples that can enjoy the full benefits that this card offers.

Be at ease as it is not the end of the world if you are unable to farm this card as its effects can be replaced with more accessible story cards.

A list of Story Cards with similar effects can be found below:

This limited event runs from December 23, 2022 to January 13, 2023.
