柴犬子在周围的人眼中看起来只不过是一个茶色头发有点卷的普通女孩子。但是在石桥茶子的眼中却是一只两只腿直立行走的柴犬姿态。故事就是围绕着这两个人的日常高中生活来展开。

Chako Ishibashi is a normal middle schooler at a normal school having normal school days. However, there is one oddity in Chako's everyday life—the student sitting at the desk next to her, Shibainuko-san. What is it about her that Chako finds strange? The answer is simple: Shibainuko-san doesn't look like a human at all. Instead, she looks just like a Shiba Inu!

Polite, well-meaning, and with the mannerisms of both a dog and a human, Shibainuko-san is loved by all. However, Chako notices that her classmates seem oblivious to Shibainuko-san's physical appearance. Can a dog go to school and be a normal student?

Join Chako and her best friend Naho on bite-sized misadventures with their unusual classmate, who may or may not actually be a dog.
