Shinohara Mari

Mari is described as an "eager beaver", working really hard and doing it with a bright attitude. Mari is humble about her accomplishments. She is also smart, not just in classes, but also in her work as a Taimanin. Despite her clumsiness that embarrasses her at times, she tries to better herself every day with a smile. Mari is good-hearted and willing to hear out even demons, if they need help. At times, Mari has become scared on missions, but often overcomes those weaknesses.

Regardless of her at first appearing to be over her head on missions, she excels and has a talent for leadership, but is often too humble to assume such a position on her own, often she is more so requested by others which notice her ability over time. She often helps other Taimanin in class, like Kasumigaoka Rika.

Though, she can go overboard and exerts herself with studies until falling asleep on the spot at times. Her hobbies are sunbathing and sleeping. Favorite food is dumplings and Japanese sweets

She is a close friend of Nanase Mai, both are in the same grade, but Mari is called "senpai" regardless. While Mari isn't strict, Mai often is more serious, with them both supporting each other. While, they help other people. Mari is very shy and gets flustered easily, specially when talking about her true feelings, she often hides from others. The RPG/AT version of her has a long-running secret crush on Fuuma Kotaro.

Often tries to copy Yatsu Murasaki in her coolness, but her classmates claim nobody can take this serious. Might have a secret admirer herself in, Inabe Yuto.
