Species: Maronian
Rank: Lance Corporal
Gender: Female
Age: Younger than Kumimi, older than Tamama
Kumimi wears an trái cam, màu da cam headband, have no symbol and the colour of her skin is as same as Pururu's.
She is Beriri's childhood friend, also her best friend. Kumimi was actually a Maronian, but she was banned from Maron because she disobeyed Meru. That's why when she was a chibi, she was about to be destroyed bởi Meru, but the aim missed and Kumimi ran away from Maron to Keron. In Keron, Beriri saw her, just like she has been abandoned. Instead of adopting her, Beriri's family just let Kumimi stay at Beriri's house and hiding her from the Maron police. That's why the Maron police gave up on searching Kumimi and return back to Maron. Then in Giroro's secret base, Chibi Giroro, Chibi Keroro, Chibi Zeroro and Chibi Pururu groups in Giroro's secret base with Chibi Beriri and Chibi Kumimi. All the chibis then gives an idea for Kumimi to disquise as a Keronian with dying her skin which was blue, into Pururu's skin colour. Kumimi's fake skin colour never shows her true skin colour forever, that's why Kumimi can't be a wanted Maronian again, because Maron have forgotten about her.
Even though she was younger than Beriri, she dosen't appear just like Chibi Kururu. She looks like she's the same age with Beriri.
When she was a chibi, she have no power, but now she have a power that blew an energy beam just like Tamama, only it was called "Kumimi Energy Blast". But Tamama's beam was stronger than Kumimi's.
Kumimi admires Keronian's life so much, she even dreams to be a real Keronian.. But it never come true, because she knew if she ask Kururu, Kururu will ask her for something unusual. But even it never come true, Kumimi still relieves because most people mistakes her for a Keronian, even though that Kumimi is actually a Maronian.
