Misa Tanaka, a recurring character originating from the first Dōkyūsei visual novel and returning as a fan favorite in Dōkyūsei 2, appears as an athletic teenager. She has brown hair typically styled in a ponytail, brown tareme-shaped eyes, a slim build, and stands 158 cm tall. Her background establishes her as a dedicated track team member known for her competitive spirit and all-around athletic prowess.

In Dōkyūsei 2, Misa visits protagonist Ryunosuke's town during winter vacation as a tourist. Her storyline begins with a confrontational "violent meet-cute" encounter with Ryunosuke at the local train station, establishing a dynamic of belligerent sexual tension between them. Their relationship evolves through heated exchanges and competitive banter, reflecting her spirited and occasionally stubborn nature.

Her characterization consistently emphasizes a positive attitude, a refusal to back down from challenges, and a tendency to push herself excessively hard, sometimes leading to impulsive behavior. While not traditionally feminine in interests or demeanor, she displays moments of vulnerability and emotional depth, particularly in romantic contexts.

Misa's narrative concludes in one of the game's possible endings through a photo montage epilogue depicting her long-term relationship with Ryunosuke. This sequence shows key milestones including their marriage and eventual parenthood, presenting them as proud parents with their infant child. This conclusion represents her most significant character development across official media, transitioning from a visiting athlete to a committed partner and mother.
