Takeshi Nishigori

Takeshi Nishigori is a childhood friend and ex-rink mate of Yuuri Katsuki. He is married to Yuuko. As a child, Takeshi used to tease Yuuri for being overweight, though Yuuko was quick to defend Yuuri from his teasing. He did not share the same interest in Victor Nikiforov that Yuuri and Yuuko did. As an adult, he has a laid-back and benign personality, and often gives Yuuri blunt but practical advice. Though he still sometimes teases Yuuri like he did when they were children, he does so in a more friendly and joking way. He no longer skates seriously, but is still a fan of the sport along with his wife and daughters. (Source: Yuri!!! On Ice Wikia)
