Byakuya Mimori, alias the magical girl Glass Happiness, endured a childhood shaped by self-sacrifice at an orphanage, where she stifled her own desires to nurture younger children. Forced into independence during middle school, she inhabited a crumbling apartment, balancing part-time roles as a convenience store clerk and nightclub hostess to fund the orphanage’s survival. Her magical girl destiny emerged from manipulation: a duplicitous cat familiar, allied with developers targeting the orphanage’s land, lured her with false promises of financial relief in exchange for her combat services. Her physical presence blends muted elegance with whimsy—pale complexion framed by long gray-white hair braided with star accessories, her blue eyes reflecting weary resolve. Transformed, twin cat-eared buns crown her head, contrasting a frilly white costume, purple tights, and salmon heels. She wields a wand embellished with celestial motifs. Hardened by adversity, Mimori deflects hardship with dry references to past deprivations, like enduring weeklong fasts. She tolerates exploitation from her cigar-puffing familiar, who pilfers her earnings, forces relentless work, and posts invasive videos online. Initially treating magical duties as transactional, her guarded exterior fractures during encounters with Mira, an antagonist lieutenant. In his company, her stoicism softens: she accepts gourmet meals, wears his gifted jacket, and shares muted smiles during rainy strolls or Christmas outings, their camaraderie blooming in stolen moments away from their roles. Her magic thrives on despair—a vulnerability her familiar weaponizes. Mira’s attempts to uplift her clash with this power source, creating a fragile push-pull dynamic. Though their bond deepens through hushed conversations and mutual protection, it remains strained by loyalties to opposing sides. Later revelations confirm the familiar’s collusion with land sharks, exposing Mimori’s recruitment as part of a broader scheme. While the orphanage escapes demolition, financial instability and betrayal’s scars linger. Her connection to Mira endures ambiguously—a tapestry of tentative trust, unspoken affection, and the lingering shadow of conflict.
