Ryusei Miyamori is a pitcher and the ace for Senda.
Abe says that Miyamori throws "sharp fastballs" with "perfect control" and was amazed to think that "such a pitcher exists". He thinks the fastball is in the high 130s, has an exceptionally high number of rotations, and that those rotations are almost vertical. He even went on to call it the best "fastball" he's ever seen.
It is known that his breaking balls include a curve, and possibly a slider.
