25 years old. Adult. He absolutely hates Mobuko. Appearance: He has fox-like messy hair and long, fox-colored hair tied in the back. His features include that hairstyle and squinting eyes. He wears gloves with a family crest depicting a fox and a sword on both hands. Usually, his eyes are closed in a squint, but in tense situations—such as during combat or when restraining Kazuma—he opens them to reveal yellow, sharp eyes. Personality: He has a frank and social personality and speaks with a regional drawl. Upon meeting Hiro Sarutobi and Yuno Yukishiro, he shows a friendly attitude, but his target is solely Riku Kamegami; he showed disappointment upon learning Riku wasn't there. He only seems interested in the strong, but he is also skilled in tactics, calmly analyzing the opponent's abilities, actions, and weaknesses. Despite the personality described above, he possesses a common-sense side, such as apologizing to Hiro and the others for Kazuma Amaba's rudeness and reprimanding Kazuma for his behavior. He retired himself after sensing Hiro's combat ability, but when Shiki Suzumiya retired, he was revived along with Kazuma Amaba. His goal was to lure them out using the remaining rings as bait to knock out Aoi Inuma and the others, eventually clashing with Riku. He was stunned by Riku's hobby of wearing heavy weights. That triggered him to get serious.

Age: 10 (likely 5th grade). He absolutely hates Mobuko. Appearance: He has purple hair in an undercut style with a center part and wears a white haiku coat. There are markings around his eyes. Personality: He is polite to everyone, but he is also cold-blooded and does not hesitate to use cowardly means to win, such as setting traps while Hiro Sarutobi and the others are fighting Kazuma Amaba to toy with his opponents. Knowing the weakness of Ikkyu's Swap Map Book, he tried to obtain the remaining rings. However, just before his trick using coordination with Kanon Fuefuki succeeded, he was swapped with Tokota Kijinuma, and his ring was destroyed by Hinano Tsuruha, resulting in his defeat.

Age: 13 (likely a middle schooler). He absolutely hates Mobuko. Appearance: Characterized by lime-green hair. His eyes are blue. He wears a navy blue haiku coat. Personality: He has a rough personality. He hates ability users, and even when asked why, he refuses to listen, saying, "I have nothing to say to ability users!" When he was defeated by Hiro and the others and put in a cell, he revealed that his younger sister, Ui, went missing in the past due to an incident involving ability users, which is the reason for his hatred.
