Rojihara, Osamu

Osamu Rojihara (はら おさむ Rojihara Osamu) is a character in the Yu-Gi-Oh! SEVENS anime. He is the secretary of the Student Council at Goha #6 Elementary, working with Janko Entant and Botan Kenzaki.



Osamu is a boy with purple hair and glasses. He wears a white collared shirt, a green tie, and a blue jacket. He also wears a yellow hexagonal badge on his left lapel.


Despite having been discriminated against due to Goha #6 Elementary's Dueling traditions, Osamu still holds them in high regard and initially insisted their school's name be put first in the title of a joint meeting between the Goha #6 and #7 Student Councils. He is shown to be somewhat strict when it comes to rules, though not above being swayed from them.



Osamu, Janko and Botan are kicked off the Goha #6 Student Council.

Osamu was formerly on the Goha #6 Elementary Student Council with Janko and Botan, but they were kicked off after losing Duels to Asana Mutsuba's Heavy Cavalry Duel Club. Following this event Janko was traumatized and became reliant on the sensation of drawing cards, so Osamu and Botan made sure to carry spare boxes for Janko to draw from.[1]

Janko learned of Rush Dueling, a format that allowed the player to draw until they held five cards on each of their turns, though the traditionalist Heavy Cavalry Duel Club refused to permit them at Goha 6th Elementary. He, Osamu, and Botan decided to hold a Dark Rush Duel Tournament in secret at the old Goha 6th Elementary campus in defiance of this rule, advertising it as the "Trumpet Duet Tournament".[1]

Goha 6th Elementary[edit]

Osamu and Botan hold Janko back from drawing too many cards.

Osamu and Botan met Yuga Ohdo, the creator of Rush Dueling, at the Dark Rush Duel Tournament, and his friends Luke, Romin Kassidy, Gavin Sogetsu, Kaizo and Seatbastian. Janko began explaining the tournament to them but had one of his seizures and Osamu and Botan quickly provided cards for him to draw. As Yuga and his friends had come under the belief they were participating in the Trumpet Duet Tournament, Luke was angered over training for nothing and challenged Janko to a Rush Duel to vent his frustrations. During the Duel Osamu and Botan had to prevent Janko from breaking the rules by drawing too many cards each turn, and they were bolstered by Janko's claims of rebellion. Unfortunately after Janko was defeated by Luke they were discovered by the Heavy Cavalry Duel Club and marched back to Goha #6 Elementary, where they were joined by Yuga and his friends after Yuga was defeated by Asana in a Rush Duel.[1][2]

Yuga was eventually able to Rush Duel Asana again, and this time he defeated her. After the Duel Asana decided to allow Rush Dueling at Goha 6th Elementary and she reinstated Osamu, Botan and Janko on the Goha 6th Elementary Student Council. Janko joyfully told the student body the news, but Osamu and Botan once again had to provide cards for him to draw when he had one of his seizures.[3]

Team Battle Royal[edit]

An official Goha-sponsored Rush Duel Tournament, the Goha Rush Duel Team Battle Royal, was announced, and Osamu, Botan, and Janko entered the tournament as a three-person team.[4] Osamu, Janko, and Botan failed to place in the tournament, so they attended the finals of the Goha Rush Duel Team Battle Royal on the third day, watching Romin's victory against Roa Kassidy and Gavin's Duel against Nail Saionji and were shocked by Gavin's new "DJ G" persona. Faced with "Yggdrago the Sky Emperor", Gavin eventually returned to his normal persona and forced a DRAW, leaving Yuga and Luke to have a final Duel.[5][6]

Osamu watched Yuga and Luke's Duel. After Yuga Summoned "Hyper Engine Vast Vulcan", the Solid Vision images of the monsters began to glitch, and Osamu learned from the Duelstronauts that the Goha Duel Server was actually on the moon and the portion that contained the data for Rush Duels, the Super Rush Robot, was being eroded in an effort to uninstall Rush Dueling.[7] Yuga and Luke decided to continue their Rush Duel despite knowing it would erase the format, and Luke eventually defeated Yuga, winning the tournament. Afterwards the Rush Duel program on the surface of the moon was destroyed, but Yuga had immediately reinstalled Rush Dueling and had the Super Rush Robot reconstructed out of space debris by Nail, making it a far stronger program. Osamu and his friends then watched Luke's coronation.[8]

Goha 6 Siblings[edit]

Following the Goha Rush Duel Team Battle Royal, the Goha Siblings, the true Goha Presidents, returned to Earth and issued a challenge to Yuga and his friends with the Super Rush Robot held hostage. After Yuga and his friends lost three times to the Goha Siblings out of the required six, Gavin called a meeting of the Goha #7 and #6 Student Councils at GastroByte to fight against Yuo Goha's Fusion Summon. As Gavin and his aides Rayne and Rino introduced themselves, Janko had one of his seizures, forcing Osamu and Botan to provide him with cards to draw. After they ordered, Osamu argued with Gavin over the order of Goha #6 Elementary and Goha #7 Elementary in his presentation's title until Janko told him off and he and Gavin apologized to each other. To their shock their food had been eaten while they weren't looking, Osamu and Janko knew instantly that Botan was responsible. As they ordered again and Gavin continued his presentation, Romin arrived to join them in their meal and Osamu criticized her for being an outsider until falling for her and allowing her to stay. Osamu tried talking with Romin for the rest of the meeting and was entranced by her rage after Botan continued to eat their food. Ironically Osamu ended up unintentionally causing Rayne to fall for him after his glasses were knocked off.[9]
