Characters
Most fansites include a page about the characters in the franchise they're covering, so I thought I'd include one here. There'll be some minor spoilers on each page, but I'll try to make the character descriptions simple so that not too much is given away. Also, there are a lot of side characters in Period Cube, but I'm just going to cover the love interests and the MC for now. If you feel like practicing your Japanese, you can read the official character descriptions here. Oh yeah, I also wrote a short bit at the bottom of each page about my thoughts on each character, just because I felt like it.
