Yoshinori Miyamasu (宮益 義範, Miyamasu Yoshinori) is known as the 6th man for Kainan. Sakuragi calls him, "Space Alien" because of his distracting appearance while wearing glasses when playing basketball, he replaces with basketball sports goggles.
His unimposing presence distracts opponents from his basketball skills especially his reliable 3-point shooting, which is comparable to Jin's and Mitsui's. Though he wears glasses, when called to play, he replaces them with a pair of goggles. Yoshinori played his first game when called in by Coach Riki Takato to shut down Sakuragi. Takato correctly deduced that Sakuragi will not take Yoshinori seriously enough to properly mark him, enabling Yoshinori to be effective.
