Komaru has short, dark brown hair, green eyes, and a distinctive ahoge sticking up from her head—a trait she shares with her brother Makoto. She typically wears a sailor-style school uniform with a white shirt and brown blazer. In old family videos, her hair was styled in a neater bob cut and the ahoge wasn't present, suggesting it's a more recent development. She's physically around 15 to 17 years old, likely a first-year high school student, based on the timeline when Makoto was away.
In the original Danganronpa, Komaru came across as cheerful and supportive, encouraging her brother as he attended Hope's Peak Academy. By the time of Danganronpa: Another Episode, she's undergone a noticeable shift. She's proven herself surprisingly brave when forced to fight off Monokuma robots during a major crisis, determined to survive and find her missing family. That said, she's still hypersensitive and startles easily—she's not the type to hide her fear.
What makes her interesting is the tension between her newfound confidence and her personality quirks. She can be stubborn and a bit childish, prone to mood swings, but she pushes forward anyway. The Soldiers of Hope have noted nothing particularly unusual about her, despite everything she's been through.
