Ginro ( (ギン) (ロー) Ginrō) is Kinro's brother, and one of the village guards. He starts hanging around Senku during his stay in the village and gets roped into the plan to make Ruri antibiotics.


Ginro Anime Profile

Ginro is shorter and scrawnier than his brother. He has short blonde hair and green eyes.

Ginro wears a karate gi-like uniform and belt. He carries his spear wherever he goes.

He appears to be feminine looking and with a higher pitch voice as he was able to disguise himself as a convincing girl and join the tribe harem in the Treasure island to infiltrate the tribe and find the formula to petrification.


Ginro is the coward of the two guard brothers, albeit very full of himself and somewhat selfish. He's easily distracted by shiny things and Senku's antics, which ends with him usually working to further the scientists schemes. He is much more sincere in his cowardice and is rather open about his feelings. For example, he considered the possibility of having everyone run away from the village to avoid a fight with the Empire of Might (though after Kohaku points out that such an idea would be bad as only a scum bag would consider it as the elderly and children wouldn't be able to keep up he claims he didn't think of such an idea).

There are two main sides to him: a kinder gentler side that cares for his friends and family and a more scummy side to himself. There are times when his scummy meddling side wins over his nicer side such as when he enters the village tournament to determine who would be village chief and wed Ruri. While he initially does so to protect Ruri fro Magma, once he learns she is satisfied with marrying whoever wins (most likely a lie in part to Ruri's kind and submissive nature) Kinro immediately decides to win so he can be chief and order people around, have ramen everyday, give everyone a harem, and be a "good chief" in his own words. The villagers are so disturbed that when he loses to Senku they immediately cheer despite the fact they do not approve of Senku as an outsider. Similarly, when the Perseus sets sail, he refuses to board for fear of such a dangerous journey though pretends to swims after the ship in order to impress some girls. In addition, he tends to enjoy meddling in Chrome and Ruri's relationship. At one point, in an extra, he even suggest that he, Chrome, Kinro and Senku attack Kohaku together to see who is stronger and claims it is "fair" since Kohaku is much stronger than all of them individually (though he had a fair point).

Ginro shows regret for his cowardice often and genuinely cares about his friends, to the point where he runs off to help Senku and Chrome in a dangerous situation where they were attempting to acquire sulfur from Sulfurina, a natural sulfur spring where the gas is poisonous to breathe in. Similarly, he refuses to cut the bridge from the village to the outside despite doing so would protect their village from Hyoga's forces, because his brother Kinro would have to be sacrificed. Recently, when his brother faces the prospect of being petrified, Ginro manages to overcome his fear to protect his brother with help from Suika. This proves that despite having a scummy cowardly side, he will ultimately endure any tough situation to protect his friends and family.

He can be somewhat lazy as he tends to slack off during his duties as a guard. He often complains when he and Kinro often have to lend man power to Senku's inventions which physically exhaust them (though considering how arduous and demanding said tasks are) and celebrated alongside Kinro when Senku built a power plant that would decrease their work. He also shows a perverted side, imagining what it would be like to marry Ruri and also showing interest when Senku tries to learn more about Homura, thinking Senku was discussing what type of woman he likes. He showed interest in the use of an x ray to peek under women's clothes. Similarly, he enjoys showing off particularly in front of cute girls, as he imagined himself looking cool while facing off during the Village Tournament though in reality was beaten badly before wining. He similarly swam to the Perseus to make it look like he was brave and wanted to join his friends on their dangerous journey to the outside world when in reality he believed he would not be able to reach the ship and would return to the island looking like a hero and getting several girls to like him.

Abilities and Skills

Physical Abilities

Ginro does not appear to be physically strong by any means; he can, however, support up to at least Chrome's weight as seen when he managed to keep him held up by his spear, albeit with great difficulty. He manages to defeat Agro, though received heavy injuries in the process.


Ginro wields a primitive-looking spear.


Ginro was at some point born into Ishigami Village and took up the role of a guard with his brother.


Kingdom of Science Arc

Ginro is first introduced alongside Kinro, blocking Kohaku and Senku from entry into the village due to their policy on outsiders. Senku, unamused by this, blows bubbles with a bar of soap, causing the two of them to freak out until Chrome explains what's going on.

Ginro assisted Senku in his quest to make Ruri antibiotics, helping create electricity and overcoming his cowardice to help Senku and Chrome collect sulfuric acid. He saves Chrome from falling into the acid.

He was in on the plan for the village tournament, until the idea of becoming chief entered his head. He compromised the plan and fought Senku intending to win, but was thankfully knocked out by Senku.

  • Ginro's name can be translated as "silver wolf". This ties into his brother, Kinro's name, which means "golden wolf".
