Masaru is a stocky fair-skinned boy with short brown hair in three spikes, and brown eyes. He wears a cream-coloured shirt a sleeveless blue jacket, orange pants, and black boots. Like his fellow Newspaper Club members, he constantly carries around his journalist equipment and wears a yellow and black armband on his left bicep; Masaru carries a microphone.
Masaru claims that he is devoted to the truth, but his questions can be provocative when he is giving interviews.
Birth of Rush Duels
Masaru, Nico, and Bakuro interviewed Yuga Ohdo and Tatsuhisa "Luke" Kamijo about Rush Dueling. Although Luke claimed Rush Dueling turned common sense on its head and put one onto a new path, Bakuro found Rush Dueling to be simplistic and shallow and published an article decrying it. Yuga, Luke, Gakuto Sogetsu, and Romin Kirishima came to their office to order him to change the story, and Masaru and Nico fended them off despite Gakuto using the authority of the Student Council against them until Yuga threatened to publish their paper online, where it would likely be censored by the Goha Corporation who had been doing the same to any digital content discussing Rush Duels. Bakuro freaked out and revealed that he was the Chief to his visitors, and suggested they Duel to determine the content of the article.
Luke accepted Bakuro's challenge, and Bakuro stated that he didn't mind using Rush Dueling rules. Masaru constantly interviewed both Duelists' throughout the Duel. Bakuro was able to bring out all three of his "News Flash Machine Toughroids" and destroy all of Luke's monsters, but Luke was able to endure the turn by reducing the ATK of one "Toughroid", surviving with 100 LP. Nico believed Bakuro had won the Duel, but Luke he destroyed all of Bakuro's "Toughroids" with "Dragonic Pressure", then brought out "Dragias the Striking Dragon" and defeated Bakuro. After Bakuro's loss, Romin took Masaru's microphone and "interviewed" Bakuro, asking him how he felt about Rush Dueling now, and Bakuro admitted that he'd come to like the depth and fun of Rush Duels. Masaru, Bakuro and Nico begged Yuga not to shut down their paper; Yuga agreed not to, and Bakuro published a revised article that legitimately praised Rush Dueling; Masaru and Nico quickly distributing it the following morning.
Gakuto called Bakuro to ask if he had any information on Yuga's "Sevens Road Magician", whose legality was being disputed as it was said to have been the reason for a Duelist being disqualified during the 666th Goha Dueling Tournament. Masaru, Bakuro and Nico instead searched for information on the tournament itself, discovering a videotape with footage of the Duelist in question, Otes, being disqualified for being a Goha employee. Yoshio Atachi was sent to bring Masaru, Bakuro and Nico to the Seven Hells Hall, where Yuga was Rush Dueling Roa Kirishima, and they arrived just as Kaizo was about to disqualify Yuga. Masaru connected their VCR player to Kaizo so that Bakuro could show everyone the footage of Otes's disqualification, which also showed Roa present in the crowd during the event, resulting in Roa revealing his animosity over not being chosen to become the King of Duels. With the legality of "Sevens Road Magician" cleared up, Yuga and Roa continued their Duel with the right to the King of Duels title on the line. Yuga was pushed into a corner, but he was able to win.
Some time after Yuga and Roa's Duel, Bakuro received a penalty on his Duel Disk. Masaru, Bakuro and Nico 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 Yoshio had defeated his mother Mimi, as Mimi had inadvertently become considered one of Yuga's friends; Masaru used his microphone to interview whoever was speaking at the time. 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 Oomori also falling in.
Gakuto later came to Masaru, Bakuro and Nico to ask them about Maximum Summoning, showing them a drawing of the Maximum Monster "Yggdrago the Heavenly Emperor Dragon Tree", though Masaru had never heard of it. Masaru was with Bakuro and Nico in Goha City when they watched Yuga and Nail's Maximum Monsters, "Super Magitek Deity Magnum Over Road" and "Yggdrago the Heavenly Emperor Dragon Tree" battling from the streets below. Yuga was forced to return his Maximum to his hand and was pushed into a corner, but to Masaru's shock, Riku Endo and Katsu Kobayakawa declared their support for Yuga and were also penalized five times, as were many elementary students around Goha City. Fortunately Yuga was able to re-Maximum Summon "Magnum Over Road" again and defeated Nail, who erased the penalties on Bakuro's Duel Disk.
Goha 6th Elementary
Masaru was with Bakuro and Nico at the Newspaper Club after school one day when Luke came to them and asked them to join his new Luke Club, dubbing them members four, five, and six without their consent. Once Luke had left, Masaru and his friends quickly agreed that they wouldn't be joining the club.
Yuga, Luke, Gakuto, Romin, Ranze and Rinnosuke were all forced to transfer to Goha 6th Elementary. Nico came to Masaru Bakuro with a warning that a caterpillar track was headed for the Road Laboratory, so they enlisted the help of the Post-Apocalyptic Club to defend it, but they were all easily disarmed by the caterpillar track's driver, Caterpillio Zomyoji, scaring Yoshio and his friends away. Masaru and his friends refused to flee even as Zomyoji's track bore down on them, but fortunately they were saved by Luke's sister Haruka "Tiger" Kamijo, who challenged Zomyoji to a Rush Duel. Masaru tried to interview Tiger throughout the Duel, but his questions annoyed her and she continually sent him and Nico flying away with a yell. Tiger eventually defeated Zomyoji, but despite his loss, Zomyoji tried to dismantle the lab anyway until he was stopped by Galient Tazaki, another member of Goha 6th's Heavy Cavalry Duel Club. After they left, Masaru interviewed Tiger over her victory, and she noted that this wasn't the full strength of the Heavy Cavalry Duel Club.
Team Battle Royal
Luke began to have Goha 7th Elementary painted blue, so Masaru, Nico and Bakuro interviewed him as to why. Luke and Kaizo confirmed they were painting the school the color of "Dragias the Striking Dragon" for a two-day celebration of his ascendance on the Student Council and they both began laughing as they reveled in their power, something Bakuro called a scoop.
Masaru, Bakuro and Nico 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 interviewing Jango Arisugawa from Goha 6th Elementary's Student Council.
Masaru, Bakuro and Nico made it through the first day of the tournament as Team Newspaper Extra. On the second day, Rinnosuke contacted them and explained that Luke, Romin and Gakuto required aid in their efforts to uncover the truth behind an organization calling themselves "Goha 66", so Masaru, Bakuro and Nico went with the Post-Apocalyptic Club and the Gourmet Comrades Team to rescue them from a mob of defeated Duelists. At Bakuro's suggestion, Menzaburo, Nick and Sushiko accompanied Luke, Romin and Gakuto, while Masaru, Bakuro and Nico remained behind with the Post-Apocalyptic Club to hold off the Duelists, though they weren't thrilled by Luke's statement that he would only remember them for three days.
Despite their efforts, Masaru, Bakuro, and Nico 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 and Gakuto's Duel against Nail and witnessing Gakuto's new "Gakuting" persona. Faced with "Yggdrago the Heavenly Emperor Dragon Tree", Gakuto eventually returned to his normal persona and forced a DRAW, leaving Yuga and Luke to have a final Duel.
