Phichit Chulanont

Phichit is a Thai figure skater. He is a kind and cheerful young man, and a natural optimist. He was supposed to contrast with Yuuri, therefore he is always full of cheerfulness. Phichit enjoys taking selfies of himself and teammates, as shown when Yuuri looks through his social media page, though his love of posting to social media can sometimes cause him to get carried away and take embarrassing photos of people. Phichit is also very proud of his country, always wanting to showcase Thai media to his audience, and hopes to popularize figure skating back in Thailand.
