Phantom Brave is a strategy RPG set in the world of Ivoire, where vast seas and numerous islands make up the landscape. A powerful force is now threatening life in the various lands, and it's up to Marona, a 13-year-old orphan with the ability to communicate with phantoms, to save the day. With the help of her phantom companion Ash, Marona sets out on a journey to solve the problems occurring in Ivoire.
The game features a turn-based combat system, where Marona can attack enemies alone or summon phantoms to aid her in battle. To summon a phantom, you must confine them to an object on the screen, which affects their abilities and capabilities. Phantoms will only remain controllable for a limited number of turns, adding a layer of strategy to each encounter.
The game's story is divided into 20 episodes, each with its own unique goal to complete before progressing. Between episodes, you can visit your home on Phantom Island, where you can summon additional phantoms to join your party and replay completed episodes or enter random dungeons for extra experience and items.
