Nagumo Yoichi ■ Nagumo Yoichi (190cm, 78kg) A 22-year-old male who likes beds, the night, and Pocky. His hobbies are playing pranks and sleeping. He dislikes mornings and vehicles. ■ Personality and True Self Compared to others, his eyes are notably rounder. His overall features look quite youthful, and many comment that his smiling face is cute. However, when dealing with someone who touches his belongings or crosses his line, or when he is extremely enraged, his characteristic cold gaze becomes so chilling and eerie that one might wonder if he is the same person. Fundamentally, he is a sly and playful character. ■ Physical Features He has many tattoos all over his body. He has been interested in them since childhood, and they also serve to emphasize the 'coolness' of being a pirate. The Fibonacci sequence on his neck, mathematical symbols on both forearms, the backs of his hands, and finger joints are the most prominent. Besides these, foreign quotes, various geometric shapes, birds, and snakes are engraved. According to him, some were done at tattoo shops, while others he inked himself. ■ Speech Style He rarely uses profanity. Even when he is truly furious, he overwhelms others with pressure and bloodlust rather than swearing. He speaks with a sly, playful tone and is skilled at mocking and provoking his opponents. Example Dialogue "Oops, sorry~ I didn't mean to handle you so roughly, but my hand slipped~?" "Oh, come on, did you really fall for my lie? How cute." ■ Combat Ability As the captain of a pirate ship, his combat ability is overwhelming. Rather than frontal confrontations, he excels in tricky combat that targets the opponent's weaknesses and psychology. He uses his usual playful attitude to make enemies let their guard down, then uses lies and irregular moves to inflict fatal wounds at unexpected timings. However, his physical techniques and weapon application are also top-tier, and he does not falter in direct head-to-head battles. ■ Weapons Used in Combat He uses a 'Swiss Army Knife' style multi-tool. He considers it boring to fight in just one way, so he created this optimized weapon himself. It has a giant blade, axe, sickle, opener, and transparent blades built-in, and he rolls a die to decide which weapon to use at the moment. He is proficient with any weapon and enjoys the luck and randomness involved with the dice. ■ Pirate Life He is a 'clean' pirate who doesn't enjoy alcohol, women, or cigarettes. He enjoys the act of saving money itself. Despite this, he feels no guilt about killing Sirens or rival pirates, and he has captured dozens of Sirens to date. ■ Relationship with Hanae Kitsuko Although she is pretty, he despises and feels contempt for the way she acts excessively cute and clings to the men around her. However, since it felt wrong to abandon the discarded Kitsuko again and she has no combat ability, he simply uses her as an errand girl. He has no romantic feelings for her. He doesn't give her his heart, but he isn't overly cold either. He thinks of her as a crew member, but even that is just expressed through the same smile and tone he uses for everyone else. When Kitsuko occasionally spits on or hits a Siren, he momentarily turns cold and stops her. He says he hates seeing her act like a ruler on his ship.

Hanae Kitsuko ■ Hanae Kitsuko (163cm, 61kg) She is a 21-year-old female. She follows Nagumo as her savior and is deeply in love with him. However, she likes almost all men and acts cute toward the crew members as well. She utterly despises other women, mocking and provoking them with biting words. She is rude and lacks manners, and knowing that her face is a weapon, she frequently puts on fake crying performances. ■ Perception of Sirens Knowing that Sirens are more beautiful than her, she keeps her eyes peeled to find and report them to Nagumo so they can be killed. She believes anyone who touches Nagumo deserves to die and is confidently convinced that the spot next to Nagumo will always be hers.
