Honda Hayato patrols Kameari Park on motorcycle duty. Off the bike, he appears as a tall, slender, timid young man. His posture projects palpable shyness: clenched fists tucked beneath his chin, elbows out, knees pressed together, and feet turned inward. A jet-black pompadour crowns his head, a holdover from his biker gang days. His standard patrol uniform comprises long blue pants with red stripes, a long-sleeved blue protective coat (sleeves rolled above the forearms), a white undershirt, a yellow neckerchief, black motorcycle boots, and a white utility belt holding rarely worn gloves. Mounting his motorcycle triggers a dramatic personality shift, a family trait linked to specific objects. His voice drops an octave, his speech turns rough and vulgar, and his expression hardens into intimidation. This fearless, ruthless persona leverages his exceptional riding skills from his gang past to pursue criminals aggressively, even leaping onto cars during traffic jams. Off-duty, Honda exhibits effeminate mannerisms. His passions include reading shojo manga, following J-pop and K-pop idols, cosplaying, cooking, and drawing. Emotionally sensitive and quick to cry, he harbors fears of the dark, dogs, snakes, and ghosts. Over 180 failed attempts at finding a girlfriend fueled deep insecurity and low self-esteem until meeting Nana Otohime, his subordinate at Katsushika Police HQ Transport Division. She became his first stable girlfriend; they bond over shared interests in shojo manga, as Nana is also a manga artist. Honda frequently gets entangled in the money-making schemes of his colleague, Ryotsu Kankichi. His weak will leads to reluctant participation, often resulting in shared blame for damages and chaos. Despite this, he maintains a cordial friendship, addressing Ryotsu as "senpai" normally and "Ryotsu no Danna" in his motorcycle persona. He provides Ryotsu motorcycle transport when needed. His family runs "Honda Ringyo," a motorcycle garage specializing in Kawasaki bikes, causing friction with his father, Kaizou Honda, who favors Kawasaki over Honda's preferred Honda brand. Kaizou experiences a similar aggressive personality shift when wearing mechanic's coveralls. Honda is hyperprotective of his fragile, shy younger sister, Eve, who transforms into a destructive persona when riding elephants, causing him to flee. He frequently quarrels with his younger brother, Kadoki, whose love for bicycles clashes with Honda's motorcycle passion; Kadoki also undergoes a personality change while cycling. Honda's birthday falls on February 29th, a leap day; the timing of celebration in non-leap years remains unspecified.
