Conan

コナン

Conan is the sole child of a group of refugees stranded on an island after humanity nearly destroyed itself in World War III. At the start of the series, he resides on the island with the remaining survivors, a man he refers to as "Grandpa".
Having spent his entire life diving and fishing on the island, Conan can hold his breath underwater for an extended period. He carries a spear, which he uses for both combat and catching fish. Conan is also exceptionally strong and employs his toes in various unconventional ways, using his feet nearly as frequently as his hands.
Conan is somewhat of a wild boy, having grown up with only his grandfather for human interaction, yet he is a kind individual with an honest heart. He is particularly gentle toward Lana, a girl he befriends.
