|Anime debut||Yu-Gi-Oh! SEVENS episode 11: "No More Holding Back!"|
Sushiko is a petite young pale-skinned girl with olive eyes and black heart-shaped hair and a beauty mark beneath her lip. She wears a sleeveless black kimono with a white lining and a yellow band around the neck, armbands around her forearms in the same style with pads on the back of her hands, a brown obi with a yellow band around the center, grey tights, black socks with white edge and green wedge-heeled sandals. She also carries an oversized wooden paddle tucked into her obi.
Sushiko presents herself with grace and poise in comparison to the more energetic Nick and Menzaburo. She tends to compare matters in life to sushi rolls, and uses the term "rolled" when returning cards to her Deck during a Duel. She is also shocked when she realizes that she was inadvertently manipulated by Roa Kirishima to trigger his cousin's hunger and apologizes for her role afterwards.
Sushiko is not above arguments, squabbling with Romin over the television remote and slyly trying to convince her to watch Itamae's Case Files with her. After their Duel however, she thanks Romin for the fun match and does not hold her victory over her.
Sushiko's full name in Japanese is a play on "makizushi", a Japanese term for sushi rolls.
Birth of Rush Duels
Menzaburo told Sushiko and Nick about the Tahayasty Restaurant, which apparently had really tasty ramen. Sushiko and Nick told other people about the restaurant, which was facing a customer shortage, and their word-of-mouth soon restored the restaurant's customer base.
Roa Kirishima later hired Sushiko, Menzaburo and Nick to cater for a RoaRomin concert. Sushiko provided sushi rolls to the audience, which they waved in place of lightsticks during the Duel between Gakuto Sogetsu and Romin Kirishima. After the Duel, Sushiko, Menzaburo and Nick realized they had inadvertently aided in Gakuto's defeat and they apologized to him and Yuga, though Gakuto reassured them it wasn't their fault. Romin then tried to warn Yuga not to Duel Roa, though Yuga still accepted Roa's challenge. During the Duel, Roa called the legality of "Sevens Road Magician" into question after Yuga told them he had received the card from a Duelist disqualified from the 666th Goha Dueling Tournament who had taught him his current outlook. After Number 6 clarified the rules regarding illegal cards that would result in Yuga's disqualification if he drew it, Luke convinced Sushiko and the others that Yuga wouldn't cheat, as he wouldn't have wanted to make new rules if he didn't respect them. He rallied them to find information on "Sevens Road Magician", and Sushiko, Menzaburo and Nick began asking Goha 3rd Elementary students if they had heard of the card, but they were unsuccessful in finding any information. Yuga drew "Sevens Road Magician", but then a Relic emerged from the ground and projected the Hologram Man, who introduced himself as Otes and revealed that he had chosen Yuga to become the King of Duels. The Goha 7th Elementary Newspaper Club then arrived and projected footage of Otes giving Yuga "Sevens Road Magician" and being disqualified, clarifying that he had been so due to being a Goha employee. Sushiko and Nick spied on Number 6 as she successfully accessed the card data of "Sevens Road Magician". Otes then revealed that Roa had been blocking the information on "Sevens Road Magician" and had also been at the 666th Goha Dueling Tournament when Otes gave "Sevens Road Magician" to Yuga. He asked Otes why he hadn't been chosen as King of Duels, and Yuga offered to continue the Duel with the title on the line. Yuga was pushed into a corner, and Sushiko worried that a careless move could be the end for him, but he was able to defeat Roa. After the Duel, Otes and the Relic sank into the ground again.
Some time after Yuga and Roa's Duel, Sushiko received a penalty on her Duel Disk. Sushiko, Nick and Menzaburo went to the Road Laboratory, where Yuga explained that they and all his other friends had been penalized due to his challenge by Goha Duel Overseer Nail Saionji to retrieve the data of Yuga's Drone Kaizo, and if anyone in Yuga's group of friends lost a Duel, they would all be penalized and their accounts deleted if they received six penalties. The penalty had occurred when Mimi Atachi was defeated by her son Yoshio, as Mimi had inadvertently become considered one of Yuga's friends, something Sushiko compared to a sushi roll being rolled up. Despite the circumstances, everyone present agreed to help Yuga given that all of their accounts were on the line, but then Yuga, Luke and Gakuto were dropped into a pit leading to the Garden of Providence, with Romin and Menzaburo also falling in, though Sushiko was saved from falling in by Nick.
Sushiko later received four more penalties on her Duel Disk. Sushiko was with Menzaburo and Nick when she witnessed Nail Maximum Summoning "Yggdrago the Heavenly Emperor Dragon Tree", which coiled around the Goha Corporation Main Office. Sushiko was shocked by the large size of "Yggdrago", and watched as it battled with Yuga's own Maximum Monster, "Super Magitek Deity Magnum Over Road", expressing relief when Yuga was able to save it by returning it to his hand to negate one of Nail's attacks. Yuga was pushed into a corner and reminded of the stakes of the match, which reminded Sushiko that due to her five penalties her account would be deleted if Yuga lost the Rush Duel. She was overjoyed when Yuga was able to re-Maximum Summon "Magnum Over Road" again, and when Yuga defeated Nail, who erased the penalties on Sushiko's Duel Disk after the Rush Duel.
Goha 6th Elementary
Sushiko, Menzaburo and Nick attended the Rush Duel Training Camp with Yuga, Luke, Romin, Gakuto and the Dueling and Dinosaur Research Club and the Dueling Insects Club. Sushiko wanted to watch Itamae's Case Files on the big screen television that night, but found herself squabbling over the remote with Romin, who wanted to watch RockFes until Yuga suggested they Rush Duel over the remote. Sushiko's strategy to restore Romin's LP proved to be uniquely suited to combat Romin's own strategy of reducing her LP the generate advantage, and she tried to convince Romin to watch her drama with her, but this just angered Romin into her enraged state and she brought out both "Prima Guitarna of the Colorful Light" and "Foldablitz of the Dream Strings", but Luke then turned the television on to show an ad for Itamae's Case Files guest-starring Princess G, a guitarist Romin looked up to. Sushiko told Romin to hurry up, snapping her out of her rage, and Romin attacked Sushiko with the intent to defeat her, but Sushiko was able to prevent her "Dragon Roll the Sushi Angel" from being destroyed and remain in the Duel. On her next turn, despite restoring Romin to 4000 LP, Sushiko was able to combine "Garibel the Extra Premium Sushi Angel" with "Inside Roll Out" to defeat Romin in a One Turn Kill. After the Duel she thanked Romin for the fun match and again offered to watch Itamae's Case Files with her, an offer Romin accepted. Nick then came in with dinner for all of them. Sushiko, Menzaburo and Nick left the Rush Duel Training Camp on the second day.
Team Battle Royal
Sushiko, Menzaburo, and Nick 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. They attended the opening ceremonies of the tournament, though they were confused by President Goha initially laughing for her opening speech until she encouraged them normally. She was challenged to a Rush Duel by Roa, who wanted to talk with the incarcerated Otes and defeated her.
Sushiko, Nick and Menzaburo made it through the first day of the tournament as the Gourmet Comrades Team. Sushiko, Nick and Menzaburo received word from Rinnosuke that Luke, Romin and Gakuto were required aid in dicscovering the identities of a group calling themselves "Goha 66", and they joined forces with the Newspaper Club and Post-Apocalyptic Club to rescue Team Luke King Luke Kings from defeated Duelists trying to rejoin the tournament; Sushiko, Menzaburo and Nick accompanying Gakuto, Romin and Luke to Maximum Mountain at Bakuro Shinjitsu's suggestion. They eventually found a Stonehenge made from baking that the starving Romin and Luke began to devour, built by Sweets Kakoko, the tournament presenter, who broke Menzaburo's heart after telling him she wasn't Noodle Sorako, who Menzaburo had become enamored with after meeting her in the Garden of Providence. Kakoko revealed she was working for Goha 66 to oppose them, so Gakuto challenged her to a Duel, but Sushiko reminded Gakuto that he was still exhausted and offered to Duel instead, only for Nick to Duel due ot wanting to pay Kakoko back for hurting Menzaburo. Kakoko nearly depleted Nick's LP, worrying Gakuto, but Sushiko reassured him that Nick was fine and had a fire lit beneath him. She was proven right as Nick made a ferocious comeback, defeating Kakoko and expressing kinship with her after the Duel, though Kakoko had to return to her era, much to Nick's dismay.
Sushiko, Menzaburo, Nick, Romin, Luke and Gakuto continued on to the Abandoned Dorm, reaching it after Romin and Luke swam off their food when they fell into a river. However when they arrived they were opposed by Getta Taira, Ushiro Omaeno and Kaizo, now working for Goha 66. Kaizo had joined Goha 66 in revenge for his mistreatment by Yuga and Luke and challenged Luke to a Duel. Sushiko was shocked by Kaizo's recovery of his Trap Cards during the Duel, a strategy Romin compared to a make-your-own-sushi roll, though Luke was able to successfully destroy Kaizo's recovered Trap and defeat him. After the Duel Sushiko, Menzaburo and Nick examined Kaizo's new robot body, only to find that he had escaped. Luke disabled Kaizo and they brought him into Maximum Mountain where they found the Heavy Cavalry Duel Club and Luke's sister Tiger having defeated the members of Goha 66, and Luke used Kaizo's confession switch to force him to reveal that Goha 66 were trying to take over the main Dueling server and subsequently the Goha Corporation and the Dueling world; the server itself being buried in Maximum Mountain.
Sushiko uses a Sushi Deck, composed of Fairy "Sushi Angel" monsters and Spell and Trap Cards themed around the art of rolling sushi. Sushiko's strategy parallels Romin Kirishima's in that it relies on manipulating LP, but is more focused on increasing her opponent's LP to gain advantage and fulfill the activation conditions for her cards, most notably her "Garibel the Extra Premium Sushi Angel", before quickly depleting her opponent's LP.
