Natsumi is a short-tempered girl—athletic, cute, and smart, with a reputation for being genuinely scary when she loses it. That said, she's also capable of real sweetness and bravery. She's got a sarcastic streak, especially when she's just trying to have fun, and she's definitely a video game enthusiast. What matters most to her, though, is family—both her actual relatives and her weird alien "family" the Keroro Platoon.
Birthday: December 2nd
Age: 13-16 Years
Eye Color: Brown
Hair Color: Red
Seiyu: Chiwa Saitō
At school, she's genuinely popular thanks to her incredible strength. Back in elementary school, she actually earned the nickname "Devil Summer" because of her temper, though she mellowed out considerably by middle school. Like most girls her age, she has insecurities—especially around Mutsumi Saburo, whom she has a major crush on, and she definitely has her girly-girl moments. She's got a city-girl side too; she can't handle extreme heat or power outages without falling apart.
Her close friend group at school includes Yayori and Satsuki, with Koyuki being especially important to her—Natsumi shows Koyuki around Tokyo and they develop a genuine friendship. Outside school, she's tight with Giroro and Koyuki Azumaya, though Giroro has feelings for her that go beyond friendship.
She constantly butts heads with Keroro, calling him "boke kaeru" (stupid frog) so often it's basically become his nickname. The irony? She's the one who discovered him in the first place—hiding in Fuyuki's bedroom wall in episode 1. Despite treating him like a friend-slash-servant and dumping chores on him, she eventually got used to the whole alien squad (except Mois, whom she trusts from the start). She even developed some actual feelings for Giroro somewhere along the way.
When things got serious, Kururu built her a special neck brace that transforms her into a real-life Gundam. She uses it whenever the team needs the firepower.
Her favorite food is baked sweet potatoes. Anything creepy-crawly—especially slugs—completely freaks her out. Her name means "summer beauty" (with literal kanji for "summer"), which fits the vibe she's got going.
