First of all, the game is in Japanese and no other language, and sometimes, a VPN connected to Japan is required.
But with that out of the way, Mikonote is a really really good-looking game, with beautiful artwork.
As for the gameplay, it's a pretty standard turn-based anime RPG with gacha elements. Players gather certain resources to make their waifus stronger, as well as material which will be used for the gacha. And speaking of the gacha, it's pretty standard as well, with OK rates. Still a lot better than FGO, I assure you. That's everything for now. Start a new game?
