Tousen Shimogamo became the Shimogamo family matriarch after her husband Soichiro's death. As a tanuki, she possesses shapeshifting abilities, though these fail during thunderstorms due to severe astrapophobia, causing her to lose transformation capabilities when frightened by lightning. Her preferred public presentation is a male-presenting form known as the "Black Prince," which she assumes for activities like playing pool and interacting with humans, contributing to her theatrical and protective persona; she maintains this form consistently outside work. Following Soichiro's demise, she took primary responsibility for raising her four sons—Yaichiro, Yajiro, Yasaburo, and Yashiro—striving to compensate for their father's absence. She defends them against criticism and remains openly proud despite the tanuki community labeling them failures. She maintains familial bonds, including visiting her elderly mother during the second season's events. Her background includes a prior engagement to Soichiro's brother, Soun Ebisugawa, before marrying Soichiro. This history fueled Soun's jealousy and eventual betrayal of Soichiro, deepening the rift between their families. Tousen managed household affairs and supported her sons through subsequent conflicts, including Soun's antagonism and the threat posed by the Friday Fellows. Her character development involves navigating grief while ensuring family cohesion. She exhibits resilience against ongoing challenges like Yajiro's self-imposed exile as a frog and Yaichiro's leadership struggles. Her actions focus on preserving Soichiro's legacy and fostering reconciliation, such as accepting Kaisei Ebisugawa's reinstated engagement to Yasaburo by the series' conclusion.
