The pacing is very slow. I started this because I wanted something with an intense competition, but the first trial didn't even start until 27% in. The trial itself was pretty underwhelming too.
I don't care about any of the characters. Xio's probably my favorite just because he doesn't talk much so he can't be as annoying as the others. I agree with people saying that it feels very juvenile. It feels like a story about middle school children.
