Yūdai Jakuzure

Assistant coach of the prestigious "Rengecha FSC" in Kyoto. 28 years old. Nicknamed Jackie. With a friendly personality, he hit it off with Tsukasa due to being of the same generation and having similar positions. When Tsukasa proposed, "Could you teach me the jump coaching method?" he readily agreed with a "Sure thing!?" While studying for the technical specialist qualification exam, he took the Yamato mother and daughter to watch the All Japan Novice A competition. By chance, he sat near the Kago father and daughter, playing the same role as Sekoma during the Chubu Block Tournament in the story.
