So, aside for my love for anime, i watched it for the science. And honestly, this time i was kinda disappointed. Don't get me wrong, if you enjoyed the first season, you'll still enjoy this one. The anime is great i guess I'm just nitpicking. The thing is, I loved the simple way the topics wee explained in the first season, but this season, it seemed like more drama, less science to me. I also felt like that the science was more difficult to understand than last time, although it could just be because the topics they handled this time were slightly more complicated. All in all,its basically the same format as last season, with the focus moving from RBC to WBC. if you want to enjoy some anime and learn biology at the same time, this is your stop!
