Takako Matsudaira 松平貴子

Second-year student at Mitsuba Academy High School.

She is distinguished by her long, curly brown hair. She sat next to Shinokita in Class 2-F after he transferred there. She is Yukiya's cousin.

Recognized for her talent for strategy, she initially operated as a "shadow strategist" for the Kanto Bancho Alliance under duress, but later stepped into the public eye as the Alliance's vice-commander. She is frequently seen with Yukiya and often acts as a guardian figure to him. Within the Kanto Bancho Alliance, she appears to handle most of the practical operations in Yukiya's stead and is well-liked by the members.

She is one of the women who has fallen for Shinokita.
