"Let's get grilled meat tonight!"
―Taro's final words to Tatsuya before leaving for his part-time job.[src]

Taro Satou (佐藤 太郎 Satō Tarō) was an aspiring musician and the roommate of Tatsuya Kishida who was murdered by Blood Stalk. His face was later switched with Takumi Katsuragi, who the latter would eventually become Sento Kiryu.

Character History

Satou was friends with Tatsuya Kishida during middle school and formed a band called Tsunagizu (ツナ義ーズ Tsunagīzu) with him in their adulthood. On September 5, Taro left for a job offer at Takumi Katsuragi's apartment, which was the last time he was seen.

Because of his appearance and amnesia, Sento Kiryu was mistaken for Satou. However, it is revealed that Sento is actually Takumi Katsuragi, while Satou turned out to have been killed by Blood Stalk and his appearance changed to Takumi's, with Ryuga Banjo being framed for for the murder of "Takumi".

In the new world, Taro and the rest of his friends are alive, and their band has grown to massive popularity, to the point where they were already performing at the Nippon Budokan, with Soichi Isurugi being a fan. Soichi also mistakes Sento as Satou due to their similar looks and ask for his autograph.

In an altered timeline, both Sento Kiryu and Ryuga Banjo were fans of him, and the entire cafe nascita was designated a Lynks Fan cafe.


According to Tatsuya, he is hinted as a rebellious man who has a large dream of living a luxurious life should their band Lynks become successful. His former apartment implied Taro as a man who lacked a sense of hygiene. Despite all these negative traits, he is nevertheless kind to his friends as his job application in Katsuragi's lab stems from the need to provide Tatsuya with financial support.

Behind the Scenes


As Sento is physically identical to Taro, he is also portrayed by Atsuhiro Inukai (犬飼 貴丈 Inukai Atsuhiro). Once applied with Takumi Katsuragi's likeness, his cadaver is portrayed by Yukiaki Kiyama (木山 廉彬 Kiyama Yukiaki). As a joke, Inukai introduced himself as playing Taro Satou instead of Sento Kiryu during the press conference of Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders.[1], and again for a second time in Chou Eiyuu Sai Kamen Rider × Super Sentai Live & Show 2018.



Despite being a short-lived character, Taro's defining trait of how he shouted "Let's get grilled meat tonight!" (夜は焼肉っしょ! Yoru wa yakinikussho!) has been a trending Japanese meme in the internet, due to how he delivered the line, as well as his action of bending his body backwards. Within the internet as well, fans snapped their pictures of grilled meat while paying tribute to Taro. During earlier press conferences, Atsuhiro Inukai would introduce himself as Taro Satou while performing the line and action as well, which he would often be corrected by Eiji Akaso to introduce himself properly.

In a commercial for barbecue sauce, actor Teruyuki Kagawa bends his body while holding the Yakiniku with his chopstick is a reference to Taro Satou as well.[2]
