It's about community reward for Ioh.

Ioh's rarity and ability are depend on the number berserk demon defeated by the whole CC's player on the upcoming Raid.

Some of the rewards : 10k berserk demon = sr Ioh with new chibi, 100k berserk = new version sr Ioh with dual sword, and the highest one 150k berserk = ssr v3 Ioh that will be launched at CC v3.
