Best J-RPG game ever, friendly F2P game, no need to pay to gain all the characters, you just grind to obtain, the game mechanic is cool with puzzle, not just tap like other J-RPG, the storyline is good no cliché thing like others.
Edit: also all characters have their own compatibility, like passive skill, attack skill, heal skill, and buff/debuff skill, so you need to try all characters, to know the best META team you can try or just copy from the Internet, theres also SP character that make the game more interesting. amazing, just amazing, this game seriously needs more attention
