- "Kunisaki Chihiro, the 'National Treasure Eater'. Call me that from now on...!"
— Kunisaki Chihiro in "Oodenta Mitsuyo VS..."
Kunisaki Chihiro (國崎 千比路 Chihiro Kunisaki) is a second year at Oodachi High School and a former member of its wrestling club. After his loss against Ushio Hinomaru, he joins the sumo club.
He is tall, and muscular. He has short, black hair (greenish where the light hits) and sideburns, as well as sharp eyes, relatively long eyelashes and thick eyebrows He always wears a breathing strip on his nose. As an adult, during training, he had incipient facial hair .
Loud and brash, he's someone that relishes other people's attention. He tends to lighten up the mood, particularly when Kei is nervous or Yūma is being harsh on himself. Due to his attitude, he's also quite tactless and inappropriate. However, when the situation requires it, he focuses entirely on the match, doing his best to win, usually shouting 'STRONGEST!' to motivate himself. As such, he prefers individual competitions, even when he would still try his hardest in team competitions.
However, he's seen as holding an enormous grudge on his older brother, and the mere sight of him angers him due to bad history between them.
He's also caused some frustration in the others due to his less than stellar academic record. When he looked for support from others, he was shocked to find that both Yuuma (a former delinquent) and Hinomaru (a sumo head) were surprisingly good students, He decided to never fail a test again, but whether he made good on his promise was left unseen.
He often gives snark remarks to Kei, but he is still very supportive of him.
Much unlike Gojo Yuma, he is a true glutton that cares nothing for table manners, especially in buffet barbecues.
He initially thought to be tactless when he messes up with names, but it is later revelaed that he is genuinely bad at remembering them, when he forgets Chizuko's name.
Kunisaki is an experienced fighter who seek to achieve the absolute top of the MMA world.
Before getting into the sumo, he already was renowned as the national champion of High School in Wrestling.
He demonstrated multiple times to have an overwhelming talent for martial arts, especially utilizing suplexes to throw opponents down, being described as a genius by both Ushio Hinomaru and Sada Mizuki, as he become able to copy opponent's special moves, like when he used Ushio's Demon Wheel to defeat Araki Gennosuke in their rematch, then using Mizuji's First Quarter Cresant Moon to easily win the first round of individual battles. He then uses more modifications of Ishigaki High's wrestlers against Hinomaru in the second round of individual battles. He then go as far as emulating Sada Mizuki's technical wrestling style, with his own wrestling-based power moves sprinkled in.
He also is well versed in sports psychology, using Kanou Akihira's fear of losing against him, which enabled Kunisaki to keep attacking despite losing 1-2 in team competition at Inter-High. This becomes even more apparent when compared to Gojo Yuma, who tends to become nervous when the team competition is on the line because Kunisaki is used to competing as a wrestler, while Yuma hadn't as a karate practitioner.
Despite the fact that he was practising sumo for only a few months, during the Inter-High Tournament his skill level was already equated with that of a national treasure, considering that he had been able to defeat two of them – Hikage Tenma and Kanou Akihira – throughout the champioship. It also shows natural instinct, as he has beaten them with high-level and rare finishers.
Alsom as he progresses at Inter High, he also gave up the idea that winning by force out is a cop-out way to win, as he forced Kanou Akihira out while battling a nose bleed from Kanou's headbutt.
After the end of the Inter-High Tournament, he moved to USA to pursue his dream about being a successful MMA fighter. Nowadays, at 20 years old, he already attained a champion title in a minor league (called MLFC).
When he was in fifth grade elementary, his parents divorced and he went with his mother.
He went to America to become champion and after coming back to support Hinomaru, it is revealed that he has a 10-month old daughter.

- Much unlike sumo, in MMA, there are hidden rules where fighters from the same training gym never fight against each other, despite being an individualistic competition.
