Yui Kaoru is a Seidou High School student who rooms with Furuya Satoru. He's best known as the dependable starting catcher for the Mamiya Senior League—basically the guy every pitcher wanted behind the plate. In his generation, he's considered a prodigy, which makes sense given that he captained Japan's team in the Little League World Series back in the day.
