|Anime debut||Yu-Gi-Oh! SEVENS episode 0088: "Post-Apocalypse and Napolitan"|
Bochi is a small golden-brown dog with white markings. They wear an exaggerated spiked collar and a steel mask.
"Bochi" is the Japanese word for the Graveyard.
Birth of Rush Duels
Bochi was with Toshihiko, Yosh and Masahiko when they watched Yuga and Nail Saionji's Maximum Monsters, "Supreme Machine Magnum Overlord" and "Yggdrago the Sky Emperor" battling on their Duel Disks.
Goha 6th Elementary
Bochi was with Toshihiko, Yosh and Masahiko in the Post-Apocalyptic Club one day after school at Goha 7th Elementary when Luke came to ask Yosh to join his new Luke Club. Yosh declined due to his dedication to the Post-Apocalyptic Club, though Luke didn't seem to understand Yosh's declaration and left, telling him that he was member seven.
Yuga, Luke, Gavin, Romin Kassidy, Rayne and Rino were all forced to transfer to Goha 6th Elementary. The Newspaper Club came to Toshihiko and his friends with a warning that a caterpillar track was headed for the Road Laboratory, so they waited at the laboratory to defend it, but they were all easily disarmed by the caterpillar track's driver, Caterpillio Zomyoji, ho dismantled their costumes, including Bochi's collar and mask, scaring them away in embarrassment at having their costumes stripped from them.
Team Battle Royal
Toshihiko, Yosh and Masahiko learned about the Goha Rush Duel Team Battle Royal from Sweets Kakoko's announcement. They decided to enter as a team, attending the registration at Goha Stadium and bringing Bochi with them. They attended the opening ceremonies of the tournament, where Roa interrupted the Goha President's opening speech and challenged her to a Rush Duel, as he wanted to talk with the incarcerated Otes. Roa defeated Goha, who became woozy after the Duel and fell off her platform, though Yosh caught her and asked if she was okay.
Toshihiko, Yosh and Masahiko made it through the first day of the tournament as the Post-Apocalyptic Conquerors. On the second day, Rino contacted them and explained that Luke, Romin and Gavin required aid in their efforts to uncover the truth behind an organization calling themselves "Goha 66", so Bochi accompanied Toshihiko, Yosh, Masahiko, the Newspaper Club and the Gourmet Comrades Team to rescue them from a mob of defeated Duelists. At Scoop's suggestion, Saburamen, Nick and Sushiko accompanied Luke, Romin and Gavin, while Bochi, Toshihiko, Yosh, and Masahiko remained behind with Scoop, Masaru and Nico to hold off the Duelists.
Despite their efforts, Toshihiko, Yosh and Masahiko failed to place in the tournament, so Bochi attended the finals of the Goha Rush Duel Team Battle Royal with them on the third day, watching Romin's victory against Roa and Gavin's Duel against Nail. Faced with "Yggdrago the Sky Emperor", Gavin eventually returned to his normal persona after a power outage in the stadium and forced a DRAW, leaving Yuga and Luke to have a final Duel.
Bochi watched Yuga and Luke's Rush Duel, and was stunned when Yuga Maximum Summoned "Hyper Engine Vast Vulcan" against Luke. Afterwards the power in the stadium began to fail again, revealed to be due to the Goha Duel Server being hacked, and Bochi witnessed the revelation of the Goha Duel Server on the moon and the Rush Duel Program contained within, under attack by Goha Enterprises Drones that were uninstalling it and had been all tournament. Despite knowing their Duel would complete the uninstallation, Yuga and Luke continued to Duel, and Luke eventually won, resulting in the uninstallation of Rush Dueling. Fortunately Yuga and Nail were able to reinstall the program and install it in the Super Rush Robot to protect it from another attack. Bochi then watched Luke's coronation as King of Duels.
Goha 6 Siblings
Romin had Buff Grimes wash Yosh, Swirly and the Concert Band Clubmembers while they were in their costumes, and Bochi sat beneath them on the clothesline they had been pegged to until Yuga began drying them with his new air-conditioning Road.
Bochi, Toshihiko, Yosh and Masahiko watched the Rush Duel between Yuga and The☆Lukeman as it was being broadcast across Goha City, including Yuo Goha's demands for The☆Lukeman and Yuga to Duel seriously. During the Duel the Goha Meteor Shower began to occur and a meteor entered the atmosphere above Yuga. Yuga blocked the meteor with his Duel Disk and acquired the "Fusion" card contained within it, allowing him to defeat The☆Lukeman and free the Super Rush Robot.
Yuga, Luke, Romin, Gavin, Swirly, Rayne and Rino were hired by Goha Enterprises, and Luke hired Toshihiko, Yosh, and Masahiko to work in his Luke Division, Bochi accompanying them. The Newspaper Club interviewed Luke, who claimed they would plan their day around what their colleagues were doing. They observed Gavin stamping documents, Romin arguing with the Chef Drones, and Yosh's mother working in the Gohanium Section. However when they visited Yuga trying to present a new vending machine, Bochi ran off and urinated on the machine, and he, Toshihiko and Masahiko were kicked out of the building as a result.
A recreation time event was planned at Goha Enterprises, with the theme "Become a zombie". When the event began, Bochi, Toshihiko, and Masahiko were quickly "zombified" and attacked Gavin, Rayne and Rino in a hallway. Yosh arrived and knocked his friends down, apologizing for failing to save them, and when the rest of the horde arrived, Bochi joined Masahiko in attacking Rino, biting onto his pants. Rino, Rayne and Yosh remained behind to let Gavin escape, allowing the horde to zombify them. Bochi and the horde later emerged on the helipad to find Gavin there as one of the last "survivors", and according to Yuga's orders as the "Zombie King", Zo Ikitenai challenged Gavin to a Rush Duel, Gavin vowing to Duel all the zombies if he had to. After Gavin defeated Zo, the event ended at 3pm and Bochi returned to his normal disposition and cheerfully barked at Gavin.
