Kuromi Kurihashi

Kuromi Kurihashi is the main protagonist of Keroro Gunsou: A New Invasion. Her partner is Garuru.

Bio
Kuromi is an arrogant, mischievous, and tough tomboy. She is quite edgy and stubborn to a point, and she hates being pushed around. Some people even call her a rowdy free spirit. She enjoys getting into trouble and would rather be cool than cute. However, despite her sour attitude, she uses her edgy personality to hide a softer, more sensitive side underneath. She is secretly a hopeless romantic and has a soft spot for cute boys. She doesn't want anyone getting on her bad side, but as long as others don't pester her, especially First Lieutenant Garuru, she gets along with them just fine.

Appearance
Kuromi is five feet and three inches tall. In the anime, she has pale skin, dark blue eyes, and black hair that is usually tied into a ponytail and has purple highlights.

Outfits

 * The first outfit that Kuromi is first seen wearing is a long-sleeved indigo shirt, a purple skirt with white highlights, grey stockings, and black flats. She also wears a pale yellow cloak. She is seen wearing this multiple times, including the first opening

Yumeko Kurihashi
Yumeko is Kuromi's mother. She doesn't understand why her daughter is so rebellious and acts so tough, but she still loves her nevertheless and expects the best from her.

First Lieutenant Garuru
At first, Kuromi distrusted Garuru since he almost blew up her house upon his first visit. After she learned of his magnificent cooking skills and his superb strength as a soldier as well as him saving her life many times, she seems to have warmed up to him. However, she's still blissfully unaware of his undying loyalty to her. In one episode she admits that she no longer sees Garuru as an alien, but more so a foreigner, which implies she trusts him more than the others.

Aoi Nishimura
Aoi is Kuromi's best friend. Aoi knows that she is able to share all of her personal secrets with Kuromi's because they trust each other. Kuromi is also aware of Aoi's secret crush.

Jou Tachikawa
Kuromi has a notable crush on Jou (whom she refers to as Jou-senpai), a senior at her school.

Kuro-san
Kuro-san is the adult version of Kuromi who appears whenever the Kurihashi siblings and the Garuru Platoon take a day off when Yumeko is absent but they require adult supervision. Tororo uses an age-changing machine, aging her into an adult woman.
