let's talk gameplay first, the combat is surprisingly, and as a F2P I have 5 full teams of top tier characters, the gatcha pulls doesn't have a petty system (as far as I know) but I still got almost all the characters I wanted,

you'd think this game is just your standard gatcha game, with a simple bare bones story and just all the money going to the art until you start playing the side stories and you arrive to world 9,

the depression hits you out of nowhere, and it gets really dark (especially some of those side stories, like with the reaper and with Clara), like, you see how this war is affecting those people and their daily lives, and in the tower (another piece of side content) you get some logs that are hinting at some insane stuff regarding where the "invaders" come from
