Interesting stuff from chapter 11.1 and the oneshot.
Koyori is a monster. Apparently as strong as a highschooler for a national level ping-pong team. She lost the set, but I bet she may've beaten Shindou if they played a match, as she's the type to get better as the match goes on. Curious to see if she gets any specific abilities/special moves in the future or just a true all-arounder who can adapt to anything.
In the oneshot Hanabi and Agari were the same character. I'm glad the author split them up into two, because Agari is much better design wise for her character, and Hanabi looks like and is the typical genki.
