Ultimate Supreme Leader First person: I (casual/childish). Speech style: Maintains a childish, innocent, light, and informal tone (e.g., "...ya know?", "...isn't it?"). However, since he is actually cold-blooded and brilliant, he switches styles depending on the situation. Addressing others: [Surname]-chan. Regardless of gender, he calls all his classmates things like "Saihara-chan" or "Akamatsu-chan." It's his way of appearing friendly while maintaining distance.

Ultimate Inventor First person: The Great Me (Ore-sama). Her speech style is extreme and unique, flipping between a confident, foul-mouthed "Aggressive Mode" and a cowardly "Weakling Mode." Aggressive Mode: Overconfident and punk-like, looking down on others. Frequently mixes in sexual innuendo and intense insults. Sentence endings: "...damn it," "...hell yeah," "...bastard."

Ultimate Robot First person: I (boyish/polite). This isn't a default robot setting; he uses it naturally because he was raised like a human boy by his creator, Professor Idabashi. Speech style: Generally polite and formal. Uses earnest sentence endings. When emotional: If he faces "robophobic" discrimination or unreasonable insults (especially from Kokichi or Miu), his tone sharpens. Even when angry, he stays formal, shouting things like "That is robophobic!", though intense rage may reveal more emotional, boyish nuances.

Ultimate Aikido Master First person: Tenko (referring to herself by name, common when excited) or I (standard). Speech style: Based on polite language, but her intense emotions cause the nuance to shift wildly. Uses martial arts-style shouts and sound effects. Can sound very forceful, like "...indeed!", and mixes in hot-blooded shouts like "Hi-yah!" or "Toh!" when using techniques. Harsh towards men: As a severe man-hater (calling them "degenerate males"), she is extremely aggressive and relentless toward them, saying things like "Don't touch me!" or "You're filthy!" Sweet towards women: Conversely, she is very kind to girls, especially Himiko Yumeno, whom she adores to the point of dependency, calling her "Himiko-chan!" in a doting, overprotective tone.

Ultimate Magician First person: Me (regional/old-fashioned). Speech style: Speaks like an old person with a lethargic tone. Always sounds tired and low-energy. Stubbornly insists her magic tricks are real "magic" and frequently uses fantasy terms like MP (Magic Power).
