Tsubomi Takane attends Salt Middle School as a childhood friend turned distant acquaintance of Shigeo Kageyama. Their shared past includes playful afternoons in a local park where Shigeo showcased psychic abilities to captivate her, but her waning interest led to a gradual separation despite concurrent schooling. This early dismissal profoundly shaped Shigeo's self-image, fueling his pursuit of growth through avenues like the Body Improvement Club. Celebrated as the school idol for her looks, Tsubomi garners widespread admiration, particularly from male peers harboring crushes. Her appearance features dark-blue hair cascading to her upper back, accented by a small pink hairclip on the left side and large sapphire-blue eyes. Later iterations omit the hairclip and render her eyes less rounded. Tsubomi navigates social spheres with image-aware caution and self-reliant reserve. She masks vulnerabilities like a post-sneeze runny nose to avoid mockery, maintaining polite friendliness that gives way to detached boredom in solitude, hinting at shallow bonds. Classmate Ichi Mezato notes her guarded trust and concealed emotions. She delivers blunt romantic rejections without softening the blow. The spirit Dimple observes her nonconformist integrity, evidenced when she declines offered candies during the Divine Tree incident. She also demonstrates shrewdness by inventing a crush story to probe Reigen's authenticity. Though rarely interacting with Shigeo in middle school, Tsubomi occasionally observes him. She witnesses his psychic repair of Emi's manuscript, commenting, "That wasn't so bad," and later identifies his photo in Reigen's office, indicating quiet awareness of his development. When relocation rumors circulate, a cascade of confessions ensues. Shigeo nervously calls her, securing a meeting at their childhood park. Amid city-wide evacuation prompted by Shigeo's emotional outburst, she waits faithfully. There, she directly rebuffs his heartfelt confession with "I have never thought of you that way," providing painful clarity that helps Shigeo process the outcome. Post-move, they sustain sporadic phone communication. Her full name, Takane Tsubomi, puns on "takane no hana" (a flower on a high peak), symbolizing an unreachable ideal that persistently inspires Shigeo. She plays piano proficiently, savors gyūdon, and avoids sea urchin.
