Matsuri has neck-length brown hair adorned with red X-shaped hair clips and red eyes. Her face looks a little masculine.
Matsuri likes festivals, befitting her name. She's a genius who loves doing experiments and invent things. She's the type who doesn't pay attention to her surroundings once she's focused on something. She feels hungry easily, so she keeps her tension low and preserves her energy by not talking too much, but apparently when it comes to a topic that interests her, she'll get very excited.
Matsuri had love doing experiments and invent things since she was just a child. Despite being so young, she had been making a fortune thanks to the patent rights she has over her inventions.
Matsuri and Akane shared a room in the dorm. Because Matsuri would devote her everything to the point of forgetting sleeps and foods once she's engrossed in her experiments, it is Akane's role to help her in leading life as a proper human being.
Their relationship is said to resemble a big brother and his younger sister. You knew of Matsuri's habit of neglecting meals and patiently deals with her when she started excitingly talk about particular topics.
