Yoshiki Nakameguro  

, 中目黒 善樹

Nakameguro is a classmate of Ken and Minatsu at their previous school, but he transferred to Hekiyou Academy after being bullied by his peers there. Although he likes Ken more than the pushy Space Siblings, Ken feels hesitant to get too close to him due to an unfortunate coincidence: Nakameguro's surname matches that of a character from Mafuyu's BL novels.
