It's seem like they doing something with gacha-rate.
Even some newby player got effect with it hahaha.

Anyway can I use dat fairy-key for other purpose except summon special stage?
Well you know... 100 stamina for 5 manyu is waste since most of us should have tons of manyu in stock.

And next event is Hello-ween... I think they will recycle old charecter with new skin once more.
So what now... they do recycle charector for sell 6 out of last 7 event + new skin for Catty and Ane.
Oh... c'mon compare to last year they do only 5 out of 8 event.
