Mayoi Neko Overrun!

Takumi Tsuzuki attends Umenomori Private Academy for free, where he's known by Fumino Serizawa, a childhood friend who often says the opposite of what she feels. At school, he's frequently distracted by Chise Umenomori, the granddaughter of the board chairman, who likes to draw him into her hobbies. When not in school, Takumi works at his adoptive sister Otome's cake shop, Stray Cats. Otome is often absent, helping others in need, which leaves Takumi to navigate his daily routine. A typical day was disrupted when Fumino woke him up early to walk to school together, briefly revealing her undergarments in the process. Otome returned home with Nozomi Kiriya, a runaway resembling a large cat, and Takumi's ordinary days turned chaotic as he tried to understand Nozomi's circumstances.
