History

Ryudo lost his life while shielding Little East Blue from raiding pirates. His death turned Yoko bitterly against pirates, and she inherited both his Navy coat and his cap. Taking up the role he left behind, she became the island's new guardian in his memory. As a commissioned officer, he was presumably a capable fighter, though the source treats his strength as an assumption rather than a shown fact.
