I'll probably pick it up if it comes out in English but I also absolutely hate console-only releases so it's a toss-up. If it gets a PC release, then definite buy.
I hope someday I'll get to read 4, since dating the wingwoman sounded interesting.
Played through a little game called Kotodama: The 7 Mysteries of Fujisawa and it left me very unsatisfied. First, it has a strip game you play through a match 3, but its way more restrictive: clicking an icon moves it to the top then the others fall down 1. So you get a ton of situations where you can see 3 identical tiles near each other, but because of the controls you can't do anything about it where in so many other bejeweled-type games you could. It also feels very un-serious to me, which is fine if the story felt comedic in the slightest, but it didn't. The story felt like it was mostly serious, so it feels very weird to go from "oh this character has a shit home-life" to stripping them in an awful bejeweled knock-off. Also it happens in normally somewhat serious moments, such as finding the first culprit to be abusing animals, so its not even like its a break from the serious that happens in things like The Shell (which also felt a little weird but maybe I'm a prude).
The story is: you are random person (gender is your choice but doesn't matter to my knowledge) who signed a contract with a demon which lets you force them to answer your question by playing bejewled. You are a late transfer, and soon meet Kagura, an eccentric girl of the school Occult research club. There's 7 mysteries and they need to get solved. You solve 4 (they are always pretty mundane answers) and the 5th has to deal with a student's suicide. Its ruled she died because of her ex, then you look over and Kagura has an evil smile. Then boom, welcome to a time loop because of another demon. Hope you like repeating an already pretty repetitive story. Even better, because you get to the 5th case again, it plays out the same, yet this time you don't get looped for whatever reason. Long story short, you reach the end, solve 6 of the mysteries, then come to the last one. The nice teacher has been prescribing a super drug that makes you violent but also smarter/stronger. Then its revealed that Kagura was also on the drug. Kagura reveals the 5th case wasn't a suicide, she killed the student due to feeling inferior. Then time loop demon shows up because I guess she no longer feels remorse (when did she ever?), they form a contract, then Kagura disappears from everyone's memory because of demon magic. Then you talk to a person for a 5 minute epilogue and imply romance with certain characters, despite no foreshadowing or even routes in the game. That's the true end btw, from what I can tell the good end she shows remorse and is otherwise pretty similar minus the epilogue, so that's something I guess.
So you have shitty gameplay, bundled with a repetitive story and an unsatifsfying ending. Its even worse because Kagura is already pretty annoying before the psycho stuff, so her getting off scot-free is very disappointing. The game also clearly didn't sell or have critical reception, so its not like they'll follow up with more. I'm sure there's a situation where a disappointing ending is fine, but its just an extra touch of crap for a mediocre game.
