I binge read the entire manga in 3 late nights to get to this point and it was worth it! What an incredible manga that does both romance and sport so incredibly well. To think of how Taiki was in the first few chapters to now, to think of Chinatsu, and everyone else. I absolutely love how incredibly well written Blue Box is!
And to be honest, even Yumeka, she's the foil, the antagonist, but she's also not a bad person, she found her way back to her passion and she genuinely does have Taiki and Chinatsu to thanks.
That being said, go beat her, Chiii!
