While I have no clue how good epi swimuit is (but I'm still getting her next)

Loquat is freaking epic when bloomed. Extremely good helper for Dend...

In fact, my current "killer" team is Lycoris, Dend, Loquat, Mei, and Sakura. Nearly everything including non-boss whaleship enemies has a 99.9% chance of getting oneshotted. Bonus points if you maxed out their crit damage increase too
