Eiichirō and Natsu both realize their classes seem to be moving on without them as they are getting ready for cram schools and entrance tests. STC has their own sort of ideas though. The top clubs in Japan have gotten together and decide to have their top players rotate between the top clubs. Included in the group is Eiichirō, and Natsu's top rival is also involved. The practices allow Eiichirō to focus on changing pace at all times and give him more experience. The bracket for the All Japan Junior is announced, and in order for Eiichirō to continue his goal he'll have to defeat the fifth seed. As the episode ends Takuma arrives back at STC. He had advanced to the Top 8 in Japan and is signing a bunch of contracts. Eiichirō challenges him to finish their match. Takuma agrees but points out he is headed over seas next week, so they'll have to do it as soon as the signings are done.
