[chaos]

hy guys i want to ask about type of fairy that just drop in revival events
i have so many of them i have used few but i dont see any benefit

I believe you are referring to Bonbori? You use them to skill up their respective event units. Every Bonbori that drops in a different revival event has the same skill as their respective event unit, so they are all different. Hope that clears things up a bit.
