I really enjoyed this one and burned through it pretty quickly. The fight at the end was fantastic, though it feels like the series is starting to dig deep into shonen tropes, with the character constantly one upping himself and quickly advancing with each fight beyond his previous limits at a rapid level of growth. That leaves it feeling like there's not much tension, since no matter what happens, you know already that Ikki is going to win.
Still, it's a fun series with a lot going for it, and I'm not expecting super deep characterization or classical literature here, it's just a light school battle series, so for the entertainment this one gets five stars.
