Mikoto Aiura, a 16-year-old PK Academy student, channels her psychic gifts as a soothsayer on a quest to find her fated soulmate—marked by pink hair, latent psychic energy, and the cryptic initials "S.K." or "K.S." Her mission grows tangled when classmate Kusuo Saiki’s overpowering aura scrambles her perceptions, pushing her toward inventive rituals to test potential matches.
Embodying gyaru flair, Mikoto sports chartreuse locks, sun-kissed skin, and rebellious accessories—a crimson Virgo hairclip, celestial face decals, and a cascade of ear piercings. Defying school dress codes, she discards collar flaps, ribbons, and socks while flaunting daring necklines. Academically languishing at 165th in her class, she dozes through lessons with self-deprecating humor, declaring herself "too ditzy for textbooks."
While Kusuo shrouds his powers in secrecy, Mikoto wields her clairvoyance openly—divining futures through crystal grids, interpreting auras, and sensing impending death via ominous "死" visions. She trades fortunes for free among peers but hustles adults with inflated rates, until a gang ambush forces Kusuo to rescue her, prompting an end to psychic profiteering. Her strategic brilliance later surfaces when coordinating Kusuo’s clones to divert volcanic magma, averting catastrophe.
Mikoto’s magnetic blend of bravado, playful teasing, and fierce loyalty cements bonds with peers like Chiyo and Chisato, whom she dubs with cheeky monikers. Though she idolizes beauty icon Kokomi Teruhashi—copying her look temporarily—Kokomi dismisses Mikoto as a rival, save in bust measurements. Unabashedly masochistic, she fantasizes about dominant romantic partners and trades risqué banter with Kusuo. Beneath the bold facade lies compassion: she supports Kusuo selflessly and wins over his grandmother Kumi by shielding her from supermarket scorn.
Guided by a plush, opulent guardian spirit, Mikoto bears a name steeped in mysticism: "Aiura" merges "phase" and "divination" kanji, while "Mikoto" signifies "destiny"—a moniker doubling as a pun for "love grievances." Her Virgo allegiance manifests in the scarlet hairclip anchoring her vibrant style.
Notable escapades include a hilariously misinterpreted house call from Kusuo that ends in disrobing chaos, and psychically tracking Chisato’s missing father to Puerto Rico—a mission unknowingly thwarting his suicide. Though her romantic sparks with Kusuo mature into mutual regard, she keeps the flame alive. Alongside Reita Toritsuka, she forges the "PK Psychic Kids" trio, much to Kusuo’s naming dismay.
