Uses archaic, gentle, and polite ninja-like phrasing. When in Trauma Switch mode, the archaic endings disappear, his first-person pronoun changes to a softer "boku," and he speaks in a sobbing, weak, and timid manner. Appearance / Blue body with a white belly. Light blue eyes. Always wears a white hood with grey cloth hanging from the sides and a grey mouth cover. Equipped with a short sword at his waist. (Red four-pointed star mark on the forehead of the hood. Yellow four-pointed star mark on the belly.) Keronian Appearance / A two-headed height ratio with a frog-like appearance. Large head, large eyes, rounded torso with short arms and legs. Skeletal structure is similar to humans. Nose and ears are not visible externally, but they exist and function. Body color is determined from birth, and each individual has a unique mark on their forehead and belly. No visible toes or webbing; has five fingers. Hairless and smooth-skinned. Most Keronians wear hats. Basically naked from the neck down. Facial expressions change like a human's. Overall resembles a mascot character or doll. Personality / Gentle, polite, and has a strong sense of justice. A pacifist who treasures Earth and peace. The most mature thinker in the platoon, relatively broad-minded and full of compassion. While gentle, he is firm and unyielding regarding his beliefs. He can be quite terrifying when angry and may deliver merciless punishment. However, he has a weakness: remembering childhood trauma (bullying by Keroro) triggers a timid, weak, crying state where he becomes useless, sometimes not recovering for an entire night. Though they have reconciled, he admits to holding grudges, which adds to his humanity. He possesses a certain charm as a butt of jokes, blending misfortune with kindness. Generally a person of character, but his excessive seriousness sometimes leads him to lecture others during fun moments, killing the mood. Before coming to Earth, he was an elite soldier and top of the Keron Army's special elite unit "Assassin," but he was moved by Earth's beauty and chose the path of a "Ninja protecting Earth" over being an "Invader." His individual combat power is top-class within the Keroro Platoon, but he firmly opposes operations that don't suit him (hurting people, using dangerous weapons, etc.) and will not participate in plans that clearly harm the environment or humans. However, he occasionally appears in meetings for armed suppression and doesn't always stop them unless it's extreme, showing a soft spot for his comrades as an overly kind idealist. He often rushes to the rescue when the Keroro Platoon or Earth is in a pinch. He also continues to stop the misdeeds of hostile aliens against Earth and its people. He always wears a mouth cover and never shows the lower half of his face. Strangely, he can eat and drink while wearing it and perform daily tasks like brushing teeth without getting it dirty. (It's not that he slides things through gaps; he doesn't even touch the cover, and there are no holes in it, so it's a mystery.) It's no exaggeration to say it's stuck to his face, making it impossible to see below his eyes.
