Its a long shot maybe, but anyone else playing the new games 白猫プロジェクト or 魔女クレ? These games are awesome!
White cat project Is an action rpg https://m.youtube.com/watch?v=Glxaao_HPCw The other one translates as something like Nina the witch and the clay soldiers Its more of a rts/rpg https://m.youtube.com/watch?v=CZdC12-VbmY Theyre both the usual free rpgs with gems and summons etc etc but theres no energy system so you can keep playing whenever you want.
Now if I were able to speak their language I would probably download it in an instant. The first one looks like a really fun timewaster. There are probably hundreds of great RPG's in the japan AppStore but they just dont want to release these games outside japan, sadly.
