Kuramochi has a delinquent-like personality and is usually seen together with Miyuki. He enjoys playing pranks and often plays video games with his teammates in his dorm room after their daily training. Despite Kuramochi's rough appearance, he is highly observant and possesses a concerned and caring side too. Kuramochi is the fastest player on the team, known for running two bases at a time and stealing bases easily. He has sometimes been called "invincible", but only when he gets on base. Otherwise, his teammates consider him "useless" but usually they mean it in a light manner. Kuramochi is ambidextrous, throwing and batting on both sides.
