To Zenkai you need some “Awakened Zenkai Power” Medals that you can get from Special Missions. So, these be obtained in a fully F2P way? Of course not. You can only get 1000 of those medals from the Missions, that are only enough to unlock the first LV of Zenkai Awakening which is hardly relevant. To unlock the others, you’ll have to Summon on some Special Banners that give those as an additional reward. Considering the Maximum Zenkai Level is 7 and you need 7000 Medals to achieve that, the outlook isn’t great.

Quite the contrary actually, because these Upgrades are Massive, Zenkai Fighters turn from being garbage to some of the best Fighters in the Game, and the thought that this system could be extremely P2W is really frightening.

This was supposed to be the replacement for Balance Changes, but it looks way worse currently.
