Here is an overview of the game, via its store pages:
Magic Battles Where Your Strategy Determines Victory or Defeat
Character placement and formation are the keys to victory! Attack in cooperation with teammates through the “A.O.M. System,” and decide the battle with super flashy “Magic Arts.”
Familiar characters like Asta, Yami, and Noel will appear, as well as a game-original character named Jien. This is a Black Clover story that you can only experience here.
Protect the Clover Kingdom
Frequent threats approach the Clover Kingdom. Work together with other players to protect it.
Train Your Party Members
Train your favorite characters to make them into party members all your own. Unlock the “Grimoire Board” and power them up. Setting Magic Tools on characters will grant them various effects.
Dispatch characters to various areas to return with items of all sorts. You might even discover hidden “Dungeon” quests. By clearing a Dungeon, you can obtain wonderful items.
