Yancha Gal no Anjō-san

In a high school in Kasugai, Seto is a serious student who lives a quiet and ordinary life. But when his mischievous classmate, Anna Anjō, begins teasing and hanging out with him on a regular basis, it starts an interesting relationship between them. The story follows the lives and antics of the two polar opposites, both in appearance and personality, as they develop into a romantic couple through their many playful—and sometimes erotic—interactions.

Anjō is accompanied by her female friends, Toyoda and Chita, while Seto is accompanied by his male friends, Inuyama and Tokio. As they all grow friendly with one another, each person becomes romantically linked to their respective partner within the group as the story progresses.

Most of the names of the characters are based on cities located in Aichi Prefecture.[2]

Yancha Gal no Anjō-san has been compared to other "teasing" romantic comedy manga, specifically Teasing Master Takagi-san, Uzaki-chan Wants to Hang Out!, and Don't Toy with Me, Miss Nagatoro, in that the four manga all share a similar story structure that revolves around a schoolgirl and a schoolboy who start as friends that simply hang out together, then slowly develop into a romantic couple with the flirtatious girl teasing, or "bullying" the boy, who in turn has intimate feelings for the girl, but is too shy to admit them to her.[49][50][51][52]

In August 2019, the series was nominated for the 5th Next Manga Awards in the print category and finished 19th out of 50 nominees.[53] It was also nominated for AnimeJapan's "Manga We Want to See Animated" poll that same year, and again in 2023, but failed to place in the top 10 in both years.[54][55][56] In July 2020, the series ranked eighth in the Tsutaya Comic Awards.[57]

Across the entire series, the manga currently has 1.2 million copies in circulation as of August 2023.[58][59]
