Saburo Togusa operates as a member of the Dollars and forms a core part of the van gang alongside close companions Kyouhei Kadota, Walker Yumasaki, and Erika Karisawa. He is distinguished by his fair complexion, sharp brown eyes, and chin-length dark brown hair parted down the middle. His typical attire consists of a white collared dress shirt, dark brown vest, gray jeans secured by a black belt, black loafers, and a beaded necklace.

Personality-wise, Saburo generally maintains a laid-back demeanor. He demonstrates willingness to help others but typically follows Kyouhei's lead before taking independent action. He shares Kyouhei's secondhand embarrassment regarding Walker and Erika's overt obsessions with anime and manga. His most defining traits are an intense attachment to his van—reacting with rage to any damage inflicted upon it—and fervent admiration for pop idol Ruri Hijiribe, whom he idolizes to the point of tearful displays at her concerts. As one of three vice presidents of Ruri's official fan club, this fandom is central to his identity. Historically, during his youth at Kushi High School, Saburo exhibited a combative nature, frequently instigating fights over minor provocations. This aggression mellowed under the influence of Ruri's music and Kyouhei's friendship, though extreme threats to his van, Ruri memorabilia, or close associates can trigger violent regression. One incident saw him nearly kill a man for damaging Ruri-related items in his van before intervention stopped him.

His background includes joining the Blue Squares gang with Kyouhei, Walker, and Erika, though he distrusted its leadership. The gang dissolved after members kidnapped Saki Mikajima, prompting the van gang to rescue her. They later joined the Dollars upon receiving an online invitation. Saburo also formed a significant friendship with immigrant ticket vendor Kaztano, who secured exclusive Ruri concert tickets for him.

Throughout key events, Saburo's driving proficiency and combat skills are repeatedly demonstrated. During the Mika Harima arc, he aided in rescuing Kaztano from kidnappers, utilizing strategic pursuits and coordination with Celty Sturluson. In the Saika arc, he ran over the Slasher to protect Anri Sonohara, though Shizuo Heiwajima's intervention severely damaged his van door—later replaced by Walker with an anime-themed door, causing Saburo ongoing embarrassment. The Yellow Scarves arc saw him infiltrating enemy meetings and transporting Masaomi Kida to safety after a brawl. During the Hollywood arc, he evaded the Toramaru biker gang while transporting multiple passengers, including the Orihara twins and later Mikado Ryuugamine's group, sustaining vehicle damage during the chase.

Following Kyouhei's coma from a hit-and-run in the Kadota's Coma arc, Saburo vowed lethal retaliation, threatening to drag the perpetrator to death with his van. In the Final Curtain arc, upon identifying Takashi Nasujima as the assailant, Saburo deliberately ran him over. His participation in the Wonderland spin-offs includes investigating deaths, encountering supernatural phenomena, and assisting in searches for missing persons, without notable changes to his character.

Additional details include his Dollars online handle "Red Carpet." He favors ramen but avoids spill-prone foods in his van. A favorite saying emphasizes his devotion to Ruri Hijiribe as "the world itself." Despite his attachment to the van, it is legally registered under Kyouhei's name.
