Medaka

Clad in heavy, oversized armor and wielding a formidable naginata, this brave young girl fights to reclaim her island from the ruthless Ganzack Pirates. Driven by the desire to rescue her father, who was forced into servitude to build the pirate's stronghold, she bravely stands against the invaders. Though she is tragically struck during the climactic clash between Luffy and Ganzack, she survives the ordeal and offers Luffy a lifesaver as a heartfelt token of gratitude.
