Otsu is a character from One Piece: Great Hidden Treasure of the Nanatsu Islands.


A closeup of Otsu.

Otsu is a slightly tanned old man with slicked-back white hair and a grey, pointed goatee. He has a diamond-shaped face with a pointed chin, squinted eyes, and a downward-pointing nose. He has a physical stature similar to someone of a much younger age. He wears a black jacket over a red shirt. He also wears black pants, black shoes, a grey headband, and grey sunglasses.


Otsu is a very stern person, demanding to know who Sanji, Usopp, and Chopper were when they arrived at his home. He is somewhat lighthearted, teasing Meryl and her subordinates when they threatened him.

Like many other characters, Otsu has his own unique laughter style, "Hohhohhohho".

Abilities and Powers

Otsu, despite his elderly appearance, is quite strong, having the strength to defeat one of Meryl's subordinates with one hit.


Great Hidden Treasure of the Nanatsu Islands

Otsu first appeared when Sanji, Usopp, and Chopper reached the top of a snowy mountain and arrived at Otsu's home. The old man apporached them and tried to question them, but, before he could learn much about them, Meryl and her subordinates arrived and threatened Otsu. He swiftly defeated one of them, and, after the Straw Hat Pirates defeated the enemy pirates, he invited them inside and told them about Simon and his crew.

Later, the Straw Hat Pirates returned to the top of the island to ask him more about the Simon Pirates. When the crew went back down to the village, they found Otsu in the village's tavern. Outside, the Simon Pirates took three people hostage. Otsu convinced the Straw Hat Pirates to help, and, after the Simon Pirates were defeated, he thanked the young crew and helped nurse the injured hostages. One of the three, Saki, thanked Otsu for his help and seemed to know him from some prior experience.
