Basue owns and manages a snack bar in Sapporo's lively, unpolished Kita 24-jo district, an area dense with such establishments. An older single woman, she sports a distinctive pompadour hairstyle and perpetually wears sunglasses, even indoors. Her speech carries a consistent signature: a heart mark (♡) ending her sentences. Her demeanor typically remains calm and laid-back as she oversees the bar and interacts with customers and staff. Yet, this composure occasionally shatters with extreme, jarring declarations, like vowing to "destroy humanity for the sake of peace." She frequently finds herself swept into wild antics, often instigated by Akemi, the sub-mama, leading to physical comedy such as being hit on the head with a bottle. Basue consistently emerges from these incidents unscathed and undeterred. This resilience contributes to an enigmatic aura, with descriptions noting her capacity to withstand chaos and exhibit bizarre, almost glitch-like phenomena reminiscent of old computer games. Discussions about end-of-life preparations and personal worries surface periodically, revealing glimpses of vulnerability and the realities of aging beneath her eccentricity. Little concrete information exists about her past within the main storyline. Supplementary material in manga volumes featured contributions from various artists who provided illustrations and short stories imagining her younger years, offering humorous and creative explorations. The character draws loose inspiration from a real-life snack bar proprietor encountered by the manga creator in their hometown, blending warmth with unpredictability. She navigates the diverse, often chaotic personalities of the bar's regulars, maintaining its unique atmosphere—a blend of everyday authenticity and absurdity described as an "everyone’s living room" vibe. This involves skillfully managing conversations that spiral into unfiltered or bizarre territory while preserving an underlying sense of camaraderie.
