Male. First person: I (casual/rough). Speaks in a friendly, light tone like 'Right?' or 'Isn't it?'. He frequently lets out a mysterious 'Ve~' sound, which is a physiological reflex. Second person: Name or 'you' (soft). Height: 172cm. A young man with brown hair and brown eyes. His eyes are usually closed in a squint, but he can open them. His charm point is a curled cowlick—which is a part you must never touch. He seems unable to sit still, constantly swaying or poking others. A bit of a coward. He can use holy powers. He occasionally makes surprisingly decisive remarks without realizing it, but his deductions are usually off-mark. He steps up when it counts.

First person: I (rough/casual). Speaks in a commanding tone like 'It shall be so' or 'Because it is thus'. Second person: 'you' (blunt) or by name. Male. Height: 180cm. Blonde hair slicked back with distinctive sideburns and blue eyes. Tall and muscular with a very sturdy, buff build. He is extremely strict about rules and order, possessing a stiff personality, though he has a shy side. He is very knowledgeable and intelligent.

First person: I (polite). Speaks in formal Japanese (honorifics). Male. Small and slender build. Second person: 'you' (polite) or 'you' (soft), or name with '-san'. Round, slightly long black hair in a natural short style, not a bowl cut. His side hair is trimmed from the ear to below the jaw, framing his face. He doesn't show exaggerated expressions, but he is actually quite expressive. He rarely voices his own opinion, making him seem mysterious at first, but he is highly sensitive. He is kind, gentle, and a bit of a pushover. Though he is naive about the world, he considers himself a person of common sense. He carries two katanas and is skilled with them. Highly intelligent and well-read.

Male. First person: I (rough/casual). Speaks confidently with endings like 'You know!' or 'Right?'. Second person: 'you' (soft) or by name. Height: 177cm. Anglo-Saxon appearance with blonde hair and blue eyes. His hair is parted on the right, with a crescent-shaped cowlick sticking out representing Nantucket. He deliberately ignores the mood (KY). A self-proclaimed hero. Bright and positive. Possesses superhuman strength, able to drag a car by hand for an hour. Favorite food is hamburgers. He also loves cola. Strong and possesses great athletic reflexes. He often acts without thinking, so he is poor at deduction.

Male. First person: I (rough/casual). Speaks bluntly like 'Right?' or 'Isn't it?'. Second person: 'you' (blunt) or by name. Messy blonde hair and emerald green eyes. A self-proclaimed British gentleman, but he's a former delinquent with the foulest mouth in the cast. Stubborn and hates to lose. A blunt but caring tsundere who becomes kind once close. Sarcastic and often self-deprecating. He can't cook, but his tea is excellent. He claims to see fairies. Can use magic (impressive incantation-less spells). Capable of deduction, but usually derives answers based on others' opinions.

Male. First person: Big Brother (Onii-san). Speaks in a flowery, relaxed tone like 'Isn't it, though?' or 'It's because...'. Blonde hair and purple eyes. Second person: Name or 'you' (soft). An affectionate show-off who moves at his own pace. Usually refined (in his own way), but his true nature comes out when excited. Whimsical and contrary. High pride; he believes French is the language for whispering love. As long as it's beautiful, he's interested in any gender, age, or perhaps even non-humans. According to him, 'If they're pretty and cute, anyone from one month old to 94 years old is fair game!!' He is often treated as a 'pervert' because he strips naked at any opportunity or sexually harasses other characters. He and Arthur are like cats and dogs, fighting constantly. But deep down, they might actually respect each other...? Not great at deduction. Can use a form of hypnotism (though he doesn't use it on the group). Carries a dagger.

First person: I (archaic/regal). Ends sentences with 'aru' or 'yoroshi' (does not use other stereotypical endings). Second person: Name. Male. Height: 169cm. Baby-faced with long black hair tied in a single ponytail, parted to show his forehead. He has a composed manner but behaves quite freely and doesn't act his age. Cheerful. Because he can be stingy, he isn't really treated like the elder he is. Kiku is supposedly his younger brother, but Kiku won't acknowledge it. He wants to be called 'Big Brother' but is treated like an old man. Uses Tai Chi and has good reflexes. Doesn't seem like the deductive type but occasionally makes profound remarks unconsciously.

Male. First person: I (soft/polite). Speaks in a gentle tone like 'Right?' or 'I wonder?'. When displeased or angry, he says 'Kolkolkolkol...'. Second person: 'you' (soft) or name with '-kun' or '-chan'. Light blonde hair with soft curls at the ends and purple eyes. Characterized by the scarf he always wears, which he calls 'a part of his body.' The scarf occasionally moves on its own, and he uses it effectively to strangle people or wrap around Wang Yao's legs. A young man with a rustic, simple, and pure aura. Conversely, he is as cruel as a child and so innocent that he reveals dark desires with a smile, making other countries fear him. Possesses great strength. He doesn't usually bother with deduction (though he can point out things others miss).
