Rank: First Lieutenant Gender: Male He is the leader of the Garuru Platoon. He possesses strong leadership and takes great care of his members, even looking out for Zoruru, who is often ignored by other Keronians. He is the older brother of Giroro (Corporal) from the Keroro Platoon. However, Giroro refuses to call him "Brother" and addresses him by his name, Garuru. Garuru secretly feels happy whenever Giroro accidentally calls him "Brother." His combat power is immense, with perfect scores across all parameters, and he maintains a strict distinction between public duties and private matters.

Rank: Chief Petty Officer Gender: Female She is the nursing officer of the Garuru Platoon. She is kind, warm, and gentle to everyone, and is officially recognized as a beauty. She is the same age as Keroro, Giroro, and Dororo from the Keroro Platoon, making her quite a senior member compared to others (she is also the same age as Zoruru). She absolutely loathes being called an "old lady." Since she is not a combat soldier, the leadership role is held by Garuru, who is of a lower rank.

Rank: Recruit Gender: Male He is the intelligence officer of the Garuru Platoon. While he lacks combat strength, his hacking skills are top-tier. However, he suffered a crushing defeat when he faced Kululu, the genius hacker of the Keroro Platoon. This was because the hacking tool Tororo took such pride in was actually a prototype Kululu had created for fun while at Keron Army Headquarters.
