Ichizu Bitch-chan

When Ayumi learns that her senior Yuuki is heading to Minami High School, a fairly difficult institution to enroll in, she believes her current results are insufficient to pass the entrance exam. Despite this, he gives her a word of encouragement and promises to tutor her if she succeeds.

One year passes, and Yuuki finds Ayumi to be one of the new first-year students enrolling at his school. However, he also quickly realizes that his junior has become extremely flirtatious toward him! Now fulfilling his promise, the two experience many events together—whether they be funny, embarrassing, or even romantic.
