TV Special
Description
Tsukasa Nishino starts as the most popular girl at her middle school, known for her attractive appearance featuring short blonde hair, green eyes, and a height of 158 cm. Her initial personality is flighty, confident, and somewhat hot-tempered. Early on, she becomes the first and only official girlfriend of protagonist Junpei Manaka after his impulsive confession during chin-ups. Junpei initially approaches her believing she is the girl he saw in strawberry-patterned underwear on the school rooftop, though he later discovers this is incorrect. Their relationship continues regardless.

After entering Oumi Academy while Junpei attends Izumizaka High School, Tsukasa matures into a more composed and thoughtful individual. She supports Junpei's filmmaking aspirations and maintains open communication about her relationship expectations. During high school, she temporarily breaks up with Junpei due to the challenges of attending different schools and his indecision regarding other romantic interests. They later reconcile, but their relationship faces another interruption when Junpei initiates a second breakup to focus on personal growth.

A central aspect of Tsukasa's development is discovering her passion for pastry-making. She works part-time at a French pastry shop and dreams of studying culinary arts in France after graduation. Pursuing this ambition, she trains in Paris for four years following high school, maintaining dedication to this career path.

Though not a member of the Film Studies Club at Izumizaka High, Tsukasa participates in their activities and is cast as the heroine in the club's second major production due to unanimous agreement she perfectly fits the role. Her relationships include friendships with other female leads like Aya Toujou and Satsuki Kitaoji, sometimes complicated by mutual romantic interest in Junpei.

Four years after high school graduation, Tsukasa returns from France and reunites with Junpei, rekindling their relationship. Her family background includes unnamed parents, and her maiden name "Nishino" incorporates the kanji for "west" (西), holding thematic significance within the series. She enjoys cooking, lists cherry pie as her favorite food, and occasionally uses boyish speech patterns.
