Haruna Saotome is a sharp-witted student renowned as both a prolific rumor-monger and manga artist, leveraging her knack for information dissemination to spread gossip across Mahora Academy in under two hours. A key member of the Library Exploration Club alongside Yue Ayase and Nodoka Miyazaki, she balances academic excellence with a penchant for unraveling secrets—most notably deducing Negi Springfield’s magician identity during a school tournament. When her friends withheld their prior knowledge of the truth, she weaponized her self-drawn manga to coax revelations from them. Her artistry fuels the in-universe "Mahou Shoujo" manga series, blending her obsession with magic into stories that mirror her pursuit of a Pactio contract with Negi. Securing the bond via a kiss, she gained the Imperium Graphices artifact: a sketchbook, hat, apron, and quill that animate her drawings into functional three-dimensional constructs. These creations range from shields and transport vessels like the goldfish-shaped Paru-Sama to combat golems and decoys, their potency dictated by her ingenuity and drafting speed. Strategically inventive, Haruna deploys her artifact to craft lifelike clones of allies for evasion or battlefield subterfuge, notably aiding missions in the Magic World by providing mobile shelter and confounding foes. Her tactical mind shines in clashes against adversaries like Fate’s forces, where she collaborates to analyze enemy tactics and shield comrades with defensive golems. Mischievous yet fiercely loyal, she orchestrates comedic schemes to push Nodoka and Negi into romantic scenarios, undeterred by protests. Her playful antics include sketching exaggerated caricatures of friends, occasionally provoking reprimands for risqué designs. Despite her whimsy, she exhibits acute perceptiveness, detecting crushes via physical tells—her bangs twitching like "antennae"—and claiming to smell the distinct "love reek" of infatuation. Post-graduation, she reinvents herself as a best-selling BL author in the Magic World, amassing wealth despite periodic creative blocks. During droughts, she escapes through a private warp gate for shopping sprees with friends, showcasing her entrepreneurial flair. Standing 162 cm with measurements of B87-W67-H88, her appearance alternates between dark green or pink hair across media. Born August 18 (blood type B), she loathes insects and deadlines but thrives on tea parties and crime scenes, embodying a mix of elegance and eccentricity.
