For the yen, you go to the cafe in the sewers and you can buy drinks and cake there (100 for drinks, 300 for cake).
Not sure what the other numbers are, though.

The top numbers are experience points. Remember, this is an RPG Maker game, so it's "supposed" to be an RPG
You gain enough XP per effect to level up, which in turn raises your level (the "E 12" in your image, the Effect counter, is actually your level indicator according to RPG Maker mechanics)
Bottom line is, don't worry about the those numbers on top

I was wondering why I couldn't get anything at the cafe when I got there. Thank you.
Ah, I get it. So it's like when you pick up effects, you're really picking up exp. That makes sense.

>>359Oh, sorry, I made that sound kind of deceiving. What I meant was that, every time you pick up an effect, an event occurs that enables that particular effect and levels you up at the same time. It's a good way to use the native level-up system
