Movie
Description
Natsumi Hinata stands as one of the central human characters. She is the older sister of Fuyuki Hinata, daughter of Aki and Haru Hinata, and granddaughter of Akina Hinata. Born on December 2, her name meaning "summer beauty" hints at her seasonal irritability, which earned her the childhood nickname "Devil Summer" for her violent temper during grade school. While the manga shows this temper mellowing in middle school, the anime depicts an opposite path, starting her as a crybaby who developed resilience.

She stands between 151 cm and 158 cm tall, with light tan skin, light brown eyes, and distinctive hot pink hair usually in pigtails. Her athleticism contributes to her tan and agility. Notable outfits include her Kissho Academy uniform, an orange sweater with tan skirt ensemble, and a specialized pink powered suit invented by Kururu. This suit, equipped with beam sabers, energy wings, and flight capabilities, transforms her into "Pekopon’s final line of defense" for critical missions.

Her personality blends athleticism, popularity, and a short temper worsened by summer heat. She excels in academics and sports, initially drawing intense school admiration—especially from Koyuki Azumaya—though this wanes later. Despite her tomboyish aggression, she harbors typical teenage insecurities, particularly regarding her crush, Mutsumi Saburo, whose radio show she avidly follows. Her interests include sweets, flowers, and cute objects, contrasting her fierce demeanor.

Within the Hinata household, she handles chores due to her mother Aki's frequent absences, extending this role to managing the disruptive Keroro Platoon. She initially distrusted them but gradually accepted them as a surrogate family, maintaining order through physical discipline. She directs particular ire at Sergeant Keroro, calling him "bokegaeru" (stupid frog)—a nickname he eventually accepts only from her. Their dynamic shifts between antagonism and mutual concern, seen when she temporarily used his real name after a fair victory or tried to dissuade him from joining the Garuru Platoon.

Her relationships are multifaceted:
- She fiercely protects Fuyuki, fearing betrayal by the Keroro Platoon might wound him emotionally.
- She harbors unspoken longing for her mother’s presence during family moments.
- Corporal Giroro’s covert affection influences his actions; he abandons schemes endangering her, though she remains unaware.
- She shares friendships with peers like Koyuki, whom she guides through urban Tokyo, and Yayori and Satsuki.

Natsumi possesses spiritual sensitivity, detecting the Hinata house spirit’s presence, which induces physical discomfort during manifestations. Her vulnerabilities include fear of betrayal affecting her family and despair during crises, as seen facing the Garuru Platoon’s invasion. Cross-media appearances include collaborations like Kemono Friends 3, adapting elements from Keroro Flash.
