Taro Satou

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 would eventually become Sento Kiryu. 
==Character History==
Satou was friends with Tatsuya Kishida during middle school and formed a band called Tsunagizu with him in their adulthood. On September 5, Taro left for a job offer at Takumi Katsuragi's apartment. However when he arrived, Evolto had knocked Takumi out, and killed Taro. Subsequently, both Taro and Takumi had their clothing and faces were switched. With the dead Taro on the ground, Evolto called the authorities and pinned the murder on Ryuga Banjo instead, who just arrived after the murder and found the dead "Takumi Katsuragi".
With Takumi Katsuragi's memories wiped by Evolto and his appearance changed, his current incarnation Sento Kiryu would often be mistaken for Taro Satou.
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 Tsunagizu, and the entire cafe nascita was designated a Tsunagizu Fan cafe. 
==Personality==
According to Tatsuya, he is hinted as a rebellious man who has a large dream of living a luxurious life should their band 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.
