Giroro is a character from the series Keroro Gunso and Sgt. Frog. He is ranked corporal in the Keron Army.


Giroro is the single unit mobile infantry of the Armpit Platoon. He is a red Keronian who has a scar over his left eye. His symbol is a skull which, unlike the other Keronians, is only on his hat. In lieu of a belly symbol, he diagonally straps across his body a belt with a rectangular buckle. It is revealed that it contains a picture of Natsumi. In the anime, it shows that he had a photo of him with Garuru and his father before arriving on Earth. The belt is priceless since it serves both as his good luck charm and as a reminder of his friends who died in a Keron War.This item has been passed down from his grandfather, to his father, to his mother(when they were in style for

the ladies) and then to him. Without it, he loses most of his abilities and is utterly inept as a soldier. However, as a young Keronian, he carried his skull symbol on his hat and belly and was not afflicted with the scar across his face. His often irritably short tempered self is caused by the unfocused members of the Platoon, especially Keroro, in their invasion of Pekopon. This often leads Giroro to physically assault Keroro by all means, including shoving a grenade in his mouth. Occasionally, his anger (usually triggered when defending Natsumi) drives him into "combat

mode"— where most of his intelligence is converted into battle power and he only speaks in short sentences. He is in love with Natsumi and he almost always turns into a lovesick puppy around her. He lives just outside the Hinata house, slightly under Natsumi's window. He has a love for trains which is shown on various episodes. He also has 7 different personalities. Along with the other members of the Keroro Platoon, Giroro is afraid of the Butt Firecracker.

In the past, he was a typical Keronian who trained with Keroro and Zeroro so one day he could be just like his idolized brother. Giroro seldomly wears a tailed white tuxedo, ruffled shirt, and either a black or pink bow tie, accompanied by a long, blond wig which he curls up in an old-fashioned way, to impress Natsumi.


Giroro was a typical child who was neither the group ring leader like Keroro, nor the sickly and fearful Zeroro. He idolized his older brother and was very proud of his sibling. He and Zeroro shared a unique bond during their childhood days as they were both subjected to the antics of the self-serving Keroro. This bond continues into their adulthood. It was Giroro who often saved Zeroro from near fatal disasters and gave him the compassion that Keroro did not.

After his military training, he entered a war along with Keroro and Zeroro as part of the original Keroro Platoon.

Giroro's symbol.

During the war, he witnessed the death of his friends and as a reverence to their sacrifice, he wears the belt across his body.

It is said that Giroro's scar was obtained in a fight with a tiger horse, but was revealed that it was actually Keroro who caused the scar.

Giroro's lifelong dream besides being great like his brother was, and still is, being a train conductor.

Life with the Hinata familyEdit

Giroro, upon arrival on Pekopon, first gathered information on the Hinata family before finding Keroro and entering the home by exploding through the TV. He set traps all over the house, but was easily defeated by Natsumi who evaded every single one without a scratch. Giroro, impressed by Natsumi's battle skills, spares the Hinata family

and ends up living in a tent in their backyard. A while afterwards, he rescues Neko from the rain, and she still stays with him. Giroro's relation to Natsumi and the cat represent a more sensitive side of his personality than the militaristic brutality that he is most known for, suggesting that he may simply be more serious about his military job than the others in the platoon have become, and sees chivalry as being just as appropriate a part of the job as combat.

Costumes and transformationsEdit


During episode 65, Keroro gives the Keroro Platoon an order to find the wanted criminal #303. Giroro dresses up as a man in a dark grey suit with a black tie and carries a small brown suitcase.

  • Giroro/Garuru's dad
  • Garuru - Older brother. Giroro looked up to him when he was a child, calling him "Nii-chan". Now they have a slight rivalry, and he has since dropped the honorific.
  • ' 'Keroro, Pururu, and Dororo - Keroro and Zeroro were chidhood friends with Giroro. He was basically the normal kid of the group, sometimes getting dragged along on the group's misadventures. He developed a crush on Pururu, but has since grown out of it, and was a good friend to Zeroro. As adults, Giroro still holds their friendship in regard, but occasionally gets angry at Keroro's lazy behavior.
  • Natsumi - Since Natsumi defeated Giroro in combat, the two bonded and Natsumi became his partner and crush. Though they have a few things in common—both have aggressive, no-nonsense personalities and, in an ironic twist of fate, both find Keroro an obnoxious nuisance—Natsumi remains unaware of Giroro's crush on her, but she does keep more of a level head when addressing him than with the other platoon members. (Giroro himself, however, often flips out in panic when she addresses him,) Giroro gets very jealous when it comes to someone that Natsumi has affections for. His greatest rival is Saburo, since Natsumi loves him. However in an episode Natsumi almost kissed Giroro but, of course, it was Saburo.
  • Kururu - Giroro and Kururu despise one another due to opposing ideas (Brain vs. Brawn), despite this, Kururu loves to use Giroro as a guinea pig for his experiments. Kururu has a crush on Giroro and blushes when Giroro pays extra attention to him.
  • Neko - Giroro took in Neko (Miss Furbottom in the Funimation dub) from the rain and also gave her food. Neko has since remained Giroro's pet and also a pet to the Hinata family.
  • Paul - As both Paul and Giroro are war-hardened soldiers, they developed a rivalry and often try to defeat each other each time they are in a competition. They both appear to mutually respect the other.


Giroro wields a large variety of weapons and is known as a renowned guerrilla combatant. Much of the weapons he has been using resemble ones that are used by mobile suits of the Gundam franchise, especially the RX-78. He also has a few mechas under his disposal— both flying and large type. He can summon any weapon at any given time, which is part of Keron technology. His Giroro Guided Missiles are his trademark in the first movie.
