Teoro is a villager who quickly becomes friends with Hakuoro (who he refers to as 'An-chan'). His weapon is a woodcutter axe. His wife is a bossy blonde woman named Sopoku, who is always scolding him for skipping out on his work or being drunk. He becomes one of Hakuoro's two chief lieutenants during the rebellion, though he admits that he is better at soldiering than tactics. After the rebellion, Teoro returns the Yamayura with his wife and friends, saying that he was born and raised there, so it's his only true home.
Just before Kuche-Ketchum's attack on Kakuoro's alliance meeting, Teoro suddenly arrives to warn him about the impending attack. Unbeknownst to anyone though, as everyone leaves the audience hall the defend the castle, Teoro succumbs to fatal wounds he apparently received while fleeing from the Kuche-Ketchum advance. It is later revealed that the entire village of Yamaura was wiped out by the Kuche-Ketchum on their way to the capital, and that Teoro was the only one able to get away, promising his wife Sopoku that he'd make it in time to warn everyone of the attack. As Teoro dies, his spirit joins his wife and friends in a peaceful afterlife that resembles Yamayura.
He prefers to be called "Pops" rather than his real name by the villagers, saying that it's a term of respect.
