After Chris' early retirement due to his shoulder injury, he became a first string member on his first year and had been the primary catcher by his second year.
Miyuki is perceived as very sociable and friendly. He does not open up to people or talk about his past with other people. In all actuality he is pretty closed off with himself. He is one of the few players whose room is often flocked to by other members. He is Yuki's shogi playmate and Isashiki's former massager. Kuramochi and other batchmates also frequently hang-out in his room along with freshmen teammates Sawamura and Furuya. He looks up to Chris Yuu Takigawa, his senior who had defeated him in middle school
After the 3rd years retire, Miyuki is promoted to team captain, as recommended by the former captain, Yuki Tetsuya. At first he worries about not being able to measure up, but is slowly growing more confident in his role.
