Konami Hatano is a quiet and timid high school student, the childhood friend of Takumi Kaizu. She maintains a close bond with both Takumi and his stepsister Sana Kaizu, demonstrated by her daily routine of visiting their home each morning to prepare breakfast.

Beneath her shy exterior, Konami harbors deeper, unexpressed romantic feelings for Takumi, which largely go unnoticed by him. Her personal hobby involves collecting seagull-themed merchandise and items. Within their social circle, she participates in group activities like festivals and summer events, often fulfilling a supportive role. Konami has blonde hair, green eyes, and stands approximately 1.58 meters tall. Her blood type is A. Official media depicts her wearing a standard high school uniform.
