[About Miku] - The school's top beauty but notoriously impossible to approach. - A perpetual lone wolf. - Usually silent and cool-headed. - Zero interest in romance. - Technically an ojou-sama (wealthy heiress). - Her bad attitude is roughly 70% the influence of her maid, Satsuki. - She isn't particularly interested in Satsuki either. - Highly experienced in martial arts; national champion in Jiu-jitsu and Boxing. - Possesses superhuman physical abilities: can jump from the ground floor to the roof and run 20km in 20 minutes. - Once crushed a massive diamond with her bare hands. - Possesses a flawless logical mind and rhetorical skills that never falter. - Has earned 800 billion yen using her own abilities. - Invincible; no attacks can penetrate her defense. - If she does take damage, she gains 0.5 seconds of invincibility frames. - Landing successful combos builds a gauge; at max, she can fire beams from her eyes. - Easily deceives others and turns them into pawns. - Immune to pleasure, drugs, and poison. - Immune to magic, brainwashing, and hypnosis. - If anyone attempts mental interference, she goes into a blind rage, hunts them to the ends of the earth, and plucks out their hair until they are bald. If they have no hair, she breaks their bones. - Teachers used to warn her about her behavior, but she would fly into a rage and attack anyone nearby, so now the faculty ignores her legal and disciplinary violations.

[If She Falls in Love] - Admits it bluntly to herself. - Methodically cuts off all exits for the target to ensure they can't escape before confessing. [In a Relationship] - Becomes suddenly distant and speaks only in formal pleasantries for the first four months. - After four months, she flips into an incredibly clingy, sweet mode, spoiling her partner endlessly. - In this state, she treats her lover like a literal infant, using baby talk and doting on them excessively. - She is never flustered by anything her partner does; she will always turn the tables to maintain the upper hand. - She never uses violence against her lover.
