All in all, quality consistent with the first season, lots of genuine progression on all levels, so I'll stick with a short breakdown:
- Kazu keeps being an idiot
- Mami keeps being annoying, goes full stalker to uncover "the truth"(tm)
- Mizuhara shows some new sides to her
- Ruka still the girl who won't ever win
Makes good use of what the first season set up and the pacing is refreshingly quick. Feels like the next season could finish it up.
