Airi is useful!! Insane boss destroyed by Ice Cream

#BlueArchive Special move from this boss does 999,999 extra damage against movement slowed target, and Airi can apply slow...This means we get to use this to our advantage. One Airi can deal about 6m dmg, so with 2 Airi you can take out phase 2 with minimal resource, then the only problem is getting through phase 1.
