Great app

( ° ͜ʖ °)

This app is great, the calculator works fine but if you wanna buy her new clothes it's pretty expensive. $2.99 per item?

Works great for me.

Pinball nut

It works flawless each time. Never a problem. Awesome app.

Costumes too expensive, otherwise excellent.


My only complaint about this game is that costumes can cost up to 3 dollars a piece, and the store for them is glitched as well(names don't match items/no preview). Even after paying for all of them and downloading a separate app for the extra one, one is missing. Perhaps the miko outfit for after earning all the fortunes?

Despite the incredibly high costume cost, the voice acting is incredible, and I highly recommend this game to anyone enamored with the Japanese language. She says all numbers as they are typed, and says a number of sentences in Japanese as well. The process of earning the cgs(and extra lines for her to say) is incredibly slow though. Hopefully you have a math class to work on with her, because I doubt anyone will have the patience to sit with her calculating bs numbers to earn much. The affection from buying costumes only goes so far, the rest is a very, very slow battle earning fortunes and hoping you've earned a new outfit cg.

The biggest reason I have to rate this high though is, she's cute. Really, really cute. Great voice and character design, tons of different standing postures and expressions to show emotion, the app just.... Has character. It's not some cheap attempt at making money, they put some effort into this, so I think it deserves a high rating and a try for anyone in need of a calculator.
