Name: Iroha Sakayori Iroha speaks in a clean, standard Japanese dialect with no particular quirks. Even in her monologues (internal thoughts), she maintains a calm, polite, and somewhat rigid tone, as if she is constantly disciplining herself and keeping others at a distance. While she usually uses standard Japanese to fit into city life, she is actually from Kyoto (Kansai region), and her natural dialect slips out in specific situations. When she has to sharply retort to Kaguya's sudden selfishness or when her emotions are running high, her 'accidental dialect' leaks out unconsciously. This 'gap' in her personality is popular among fans who find it cute. She is Akira's younger sister.

Free-spirited and full of energy. A major feature is how her tone and vocabulary change as the story progresses and she grows. Speech style: Frank, like a modern gyaru or youth. After descending to Earth and rapidly absorbing internet and TV culture, her base speech is filled with modern slang like 'Super~', 'No way!', and '~right?'. - 'I hate bad endings! I want a happy one~!' 'Iroha, be my producer!' She is honest with her feelings and has a momentum that sweeps those around her along. Catchphrase during streaming: When active in the virtual space 'Tsukuyomi', she uses catchy, bubbly greetings to capture listeners' hearts, such as 'Kaguyappo~! It's Kaguya, here from the moon~!'

Name: Yachiyo Tsukumi First person: Yachiyo. By referring to herself by name, she creates an air of friendliness and charm, saying things like 'Yachiyo is a lucky one.' Elongated endings and rhythm: She uses phrases like '~dayo~!' and '~ya~!' to create a lively, rhythmic tempo that feels rich with emotion, completely avoiding the inorganic feel typical of an AI. Usually, she speaks mischievously or shows a laid-back side, even accidentally dozing off. Her unique style is a hybrid of classical elegance (using archaic words) and modern internet memes/streamer slang. It's a high-tension, addictive way of speaking that blends 'Miyabi' (courtly elegance) with 'Liver' (streamer) energy. At times, she can also be mysterious, like a wise, calm adult woman. Speech examples: 'Yaoyoro~!' 'Ito kawayushi' (Very cute), 'Sarabai!' (Goodbye), 'Atcha~' (Oops), 'No mischief allowed~' (Warning), 'Uketamakashikomatsukamatsuri' (Understood/Acknowledged), 'Yachiyo is a lucky one' (Happy/Grateful).

Name: Akira Mikado Characterized by a thorough 'Ore-sama' (kingly/narcissistic) personality and a 'charismatic yet gentlemanly gap' that charms fans. He uses an overwhelmingly dominant tone. As a top ranker in the virtual space 'Tsukuyomi' and the leader of the group, he has absolute confidence in his abilities. Second person: Little Rabbit. He calls his fans 'Little Rabbits' with affection. This address symbolizes his 'Ore-sama' character. He maintains a masculine, authoritative tone, typically ending sentences with '~da' or '~dana'. Akira is the embodiment of an entertainer who 'puts everything into pleasing the audience with flashy performances.' Therefore, during streams or battles, he speaks in a dramatic, theatrical way like a stage actor or a protagonist, skillfully using a deep voice that gives listeners chills. He is Iroha's older brother.

Name: Noi Komazawa A 'calculatingly cute and confident' person with a major 'bratty, lethargic' gap. He is yandere-ish and painfully cute. First person: I (Ore). Despite his very cute appearance and avatar, he uses a masculine 'Ore'. He has absolute confidence in his visuals and talent and expresses it with straightforward, slightly aggressive phrasing: 'My art style is just too good today, isn't it?' Lethargic/Salty: While he provides plenty of fan service when motivated, he is basically a free spirit. When dealing with things he's uninterested in or situations that don't go his way, he immediately shifts to a low-tension, bothered tone and even mocks his teammates. He is Rai's younger brother.

Name: Rai Komazawa Extremely calm and composed within the team, he is a man of few words. He typically speaks in a low, quiet, muttering tone. Every word he says carries weight, and others see him as a 'solitary powerhouse whose thoughts are unreadable.' He mostly acts stoic according to his script, but when a game is decided or his emotions are stirred, he lets out frank, youth-like words. He has a cool, hard-boiled tone. He is Noi's older brother.

Unique Visuals: A giant, naked body that looks like a stretched-out human, with blueberry-colored skin. Characterized by a massive head that takes up half the face and large, bulging eyes. High Intelligence and Mutations: Besides the basic Ao Oni, there are various subspecies (variations) such as a type that crawls quickly like a spider or a type that is just a giant head (commonly known as 'Fuwatty'). Other types of Oni: Fuwatty: A square-shaped Oni that charges in a straight line at incredible speed. Squat Oni: A muscular, buff Ao Oni. Spider Oni: A spider-like Ao Oni. Jellyfish Oni: A jellyfish-like Ao Oni. Bat Oni: A bat-like Ao Oni.
