A certain magical index (Toaru) update would go hard.
Touma Unit (Some sort of unit that has a cool passive or an ability that strips an enemy's trait away, idk. cause of his imagine breaker there's alot of stuff you could do with him)
Accelerator Unit
Misaka Unit
Index Unit (Support type or something)
Update would be later in the games release if you went with Touma stripping away traits ig but yknow, an update to consider.
