Giroro's drawing of Keroro

Giroro (ギロロ) is a main character from the series Keroro Gunso. He is ranked corporal (伍長 gochou)[RANKS] in the Keron Army.


Giroro is the single unit mobile infantry of the Keroro 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 Hinata. 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 his brother and finally 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 he is defending Natsumi) would drive him into "combat mode" — where most of the time he almost always turns into a lovesick puppy when he's around her. He lives just outside the Hinata's house, slightly under Natsumi's window. He has a love for trains which is shown on various episodes. He also has about 7 different personalities. Along with the other members of the Keroro Platoon, Giroro is afraid of the Butt Firecracker (ケツ爆竹).

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. He has also proven to be a very powerful frog.

Childhood Edit

For more information see Chibi Giroro

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. During the war, he witnessed the death of his friends and as a reverence to their sacrifice, he wears the belt across his body.[1]

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.[2][3]

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 a white cat 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 Transformations Edit

Giroro's Father Edit

Ever since Giroro was young, he wanted to be an excellent Keron army soldier, just like his father. Other then that, Giroro doesn't interact much with his father.

Garuru Edit

Giroro's older brother. Giroro looked up to him when he was a child, calling him Nii-Chan, short for onii-san (兄さん,お兄さん both literally meaning Big Brother). Now they have a slight rivalry, and he has since dropped the honorific.  Despite this, he still sees Garuru as a great older brother.[4]

Keroro, Pururu, and Dororo Edit

Keroro and Zeroro were childhood 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 Chibi 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.

Giroro is much kinder to Dororo then Keroro ever was (or will be). Once, on one of their many misadventures children, he lost a precious item to save Dororo's life. They had gone back to the planet where he did so and Giroro found Dororo sifting through the gravel near the train tracks, looking for the membership card. However, Giroro stopped him, saying that he had lost something precious, but that he had saved something more important, implying that though forgotten so often as he is, Dororo is a treasured friend. Dororo has also served as a mentor to Giroro (episode 131) as a sweet potato farmer.

Natsumi Hinata Edit

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, flips out in panic or blushes when she addresses him). She also appears to have a deeper bond with him then she lets on to as she cried when he left Pekopon. Giroro gets very jealous when it comes to someone that Natsumi has affections for. His greatest rival is Saburo, since Natsumi loves him.

Kururu Edit

Giroro despises Kururu due to opposing ideas (Brain vs. Brawn). Despite this, Kururu loves to use Giroro as a guinea pig for his experiments. He pretends to have a crush on Giroro in just to mess with him. And yet in episode 265, after Giroro accidentally kisses Saburo, he secretly calls him an 'idiot' while he's spying on him, which suggests that he does have a genuine interest in the Corporal.

Neko Edit

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 friend. Giroro states that Neko is always close to him, but he doesn't mind.[4]

Paul Moriyama Edit

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.

Koyuki Azumaya Edit

Giroro seems to be a little jealous of Koyuki and Natsumi's relationship as Koyuki always seems very close to her; hugging her when they met. Once when Koyuki is staying at Natsumi's house, during their bathing time, Giroro got so jealous that he crushed the wall with his bare hand. Despite of all this, Giroro respects Koyuki as Dororo's great friend.

Fuyuki Hinata Edit

Giroro appears to like Fuyuki well enough, often trying to get him to exercise more and he usually helps Fuyuki with things, most likely to impress Natsumi.

Weapons Edit

Giroro wields a large variety of weapons and is known as a renowned guerrilla combatant. He is well-known and has connections within the Keron Army thanks to his veteranship and his prowess and is actually the best sharpshooter of them all. 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.

Trivia Edit

  • The color of Giroro's afro is blonde, which is the same color as his hair in his human form.

Weakness Edit

If he loses his belt, he becomes weak and clumsy because it is a good luck charm and also contains a photograph of Natsumi. Also, his love for Natsumi can make him falter and fail in missions, even stopping invasion attempts short. 

Also, he is afraid of ghosts and sea cucumbers. (See episode 123-A or 177)
