Otanjoubi Omedetou, Kisarazu Kyoudai!

It's the birthdays of the Kisarazu Kyoudai - Ryo and Atsushi! They are the only twin brothers combination in Tenipuri with the other group being the Fuji brothers. As such, we know that Ryo and Atsushi look exactly the same and that resulted in Mizuki getting the wrong guy to join St Rudolph. In order to distinguish them, Ryo being the elder brother wears a cap and has long hair while Atsushi has short hair and wears a headband. I wonder what Mizuki was thinking of when he got Atsushi to wear that red headband. Doesn't that get into the way when playing tennis? Well, Atsushi has more airtime as compared to his brother where we saw him during the St Ruldoph arc doubles 2 match with Yanagisawa against Momo and Kaidou. That match was stopped halfway because Momo knocked Yanagisawa out. Other than that, there were snippets of his other matches at times. As for Ryo, he didn't get a chance to appear during the Rokkaku arc so it was only until the Senbatsu arc when he had a short match with Atsushi. Thus, it's hard to guess who is actually superior among them. Although there is a sense of rivalry between them, they seem to be closer than the Fuji brothers who were initially not on speaking terms due to Yuuta's inferior complex. At least, they don't feel the extreme need to outdo each other. Now that Rokkaku has been knocked out in the Nationals and St Rudolph is not in the competition, I doubt the twins will appear again in the manga.
