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.

Character and AppearanceEdit

Giroro is the single unit mobile infantry of the Keroro Platoon. He has proven to be very strong and resilient, and has been training to be a soldier nearly his entire life.

He is a red adult Keronian with a scar on the left side of his face. He has slanted, large eyes and wears a maroon hat of the same style as most Keronians. His symbol is a small yellow skull. 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. Without the belt, 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.

Giroro refuses to live in the base, preferring to take up residency in a small tent in the backyard.

He has shown a deep love for trains, and a strong fear of sea cucumbers and ghosts. 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. However, it seems that he may have taken his training more seriously than his friends in an effort to live up to his families expectations of him.

Personality Edit

Giroro has a very short temper, and is angered easily by incompetence and acts that he deems unfit for soldiers. Keroro happens to be both incompetent and doesn't play the part of a soldier, so he clashes with Giroro a lot, and the two can often be seen fighting.

When Giroro first arrived on Pekopon, he was much more aggressive than he is later in the series, and he frequently used physical force to whip Keroro and the others into shape. He also acted very insubordinate, and left the platoon for a time and tried to take over the planet by himself.

Though he is hot-headed and aggressive, he is a good person at heart and he mostly tries to do what he thinks is right and what is best for everyone. He is loyal to his friends and tries to do what he can and what he feels is in order so that they are safe and happy.

Childhood Edit

For more information see Chibi Giroro

Giroro was a decidedly atypical child. He was unusually intense for someone of his age and at approximately 10 years old he began to train himself vigorously for the army. As in adulthood, he idolized his older brother and was very proud of him (though, unlike in his adult years, he did not feel the fear and intimidation for his brother that he develops later on).

Often, it was Giroro rather than Keroro who would often have to save the weak and sickly Zeroro from near fatal disasters.

After his military training, he entered a war along with Keroro and Zeroro, and appears to have suffered long-term damage from it; he is easily startled and has a very 'war' mindset. He also once mistook a pinecone for a grenade. he has razor-sharp reflexes and is always expecting an attack. To him, everything is a battle.

It is said that Giroro's scar was obtained during a battle, but was revealed that it was actually Keroro who caused the scar.[1][2]

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

Life with the Hinata family Edit

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 Father Edit

Ever since Giroro was young, he wanted to be an excellent Keronian army soldier, just like his father. Other then that, Giroro doesn't interact much with his father, other than stating that his childhood was a bit volatile due to his father's being a bit of a maniac.

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). He has since dropped the honorific, presumably out of respect for his brother's rank and due to their age (though he has slipped up once or twice).[3] Giroro reveres Garuru and seems to feel an intense intimidation bordering on fear towards him, despite Garuru's not presenting a specific threat to him.

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, like the rest of the group, but has since grown out of it.

Natsumi Hinata Edit

Since Natsumi made it through Giroro's traps that he set and due to their somewhat similar mindsets, the two bonded and Natsumi became his partner and crush. It's been shown that it's possible that Natsumi has a slight crush on Giroro.

Giroro has a passionate crush on the young girl, and (especially towards the beginning of the series) he gets flustered when she speaks to him and appears on the verge of being unable to keep it in his pants when he's around her. Many would call this gross, seeing as how Natsumi Hinata is thirteen (13) at the beginning of the series and Giroro is clearly middle-aged. He does not appear to be an actual pedophile, but it seems that he just hasn't really thought about her age.

Giroro gets very jealous when it comes to someone that Natsumi has affections for.

Kururu Edit

Giroro dislikes Kururu due to opposing ideas (Brain vs. Brawn) and does not interact with him a whole lot, though he does get flustered when Kululu teases him and the sergeant major seems to make Giroro uncomfortable.

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.[3]

Koyuki Azumaya Edit

Giroro seems to be jealous of Natsumi's and Koyuki's relationship, and he views Koyuki as a threat to his chance (however nonexistent it may be) at being Natsumi's partner. Koyuki does not appear to share these feelings, however.

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.

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.

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.
