Lively and passionate for sports, Hagumi is known for her sunny disposition and energetic nature. She is cheery and can be a bit of a show-off, but she usually doesn't take things too far. She tries to convince others to indulge in her sporty hobbies at times. Despite her tomboyish personality, Hagumi has an affinity for cute things and has a complex over her boyish appearance. She especially loves Michelle's costume due to how it resembles a large stuffed bear. She can also be surprisingly sensitive and cautious of others' emotions as well, and dislikes competition due to the fact that somebody will always lose and feel bad for it.
