Oh wow, this brings back memories. I read this manga long time ago when a local publisher translated it. I don't know where I put my copies (or maybe my mom could've thrown them away...). But it was a great read! Classic shoujo with the dynamics of playing judo. Thanks for sharing this!
Btw just a heads up on page 46 I noticed you put up same translation in two panels, the 'Koji-niichan's on a high-rated company's team' part.
