User blog comment:Dorayaki/Drefes! --- boys version of "Aikatsu!"? What's your thought?/@comment-24848025-20160331171359

Personally I'm not surprised that Drefes! is starting out on it's own at first. There is no guarentee the series or game will do well - and if it tanks they can jettison it without having it affect Aikatsu.

Basically, I think it'll be at least a year - if not years - for a collaboration between the two happens. Though, we might see the real life groups perform together at special stages like Animelo Summer Live.
