Konatsu Toro is a 16-year-old student in Class 2-A at Gokurakuin Girls' High School. She stands 143 cm tall, weighs 32 kg, and has physical measurements of 70-55-75 cm. Her appearance features yellow or blonde hair and brown eyes.

As a classmate and frequent companion of protagonist Aya Akabane, Konatsu often bears the brunt of Aya's frustrations. Aya regularly grabs Konatsu by her ponytail, dangling or swinging her, especially when Aya's schemes fail or she becomes agitated. Despite this treatment, Konatsu maintains persistent admiration for Aya and does not intentionally provoke these reactions.

Konatsu's personality includes a tendency to become easily distracted or captivated by small, cute objects like puppies, kittens, or butterflies. Her closest friend within the group is Ai Nanasato, portrayed as comparatively normal. Konatsu's interactions sometimes involve involuntary participation in embarrassing situations, including incidents of public underwear removal, often occurring in retaliation after similar actions toward Aya.

Her role remains consistent as a supporting character who reacts to the antics of others without driving significant plot progression or undergoing personal evolution.
