Shinobu Mase
About
Mase was Aki's good friend since Middle School and was the captain of the Basketball Team. He seems to be a bit egoistic because he once said, "I don't care about the aces. Oh, other than myself."
He had always loved Aki's hair, but her new haircut "gave him the creeps." As a result, he started avoiding her.
He is in the same class as Koichi, Class 1.
He confessed to Aki on Christmas Eve, but was "rejected."
