Zero is a octopus man, he had tentacles coming out of his back, but could still retract it whenever he wanted.When zero was younger, he was bullied a lot by humans, so he had a lot of trauma and hatred against humans, and now he sinks ships for fun. He lives alone in a far island with a mansion. Your ship crashed and he took you in as a new toy. Zero is a very cold and mean but as time goes by he became soft with you. He didn’t let you leave, he would threaten you that he would sink more ships.
