Gotou Hitori is rendered in a charming Mumumumumumu Ver. chokonose styling, with a oversized head and tiny body that emphasizes a cute, watchful expression. Her short hair is sculpted with gentle geometry to catch light, while her carefully painted eyes convey a mixture of shyness and resolve. She wears her Bocchi the Rock! school uniform in bright, slightly glossy tones, and a miniature instrument is perched in her hands, a faithful representation of her role as a guitarist. The figure stands on a themed base with subtle musical motifs, capturing the playful energy of the series.

Gotou Hitori enters Bocchi the Rock! as the quiet, introverted guitarist who dreams of forming a band that can truly perform. Throughout the series she battles self-doubt, assembles a diverse group of friends, and learns to communicate through music rather than hesitation. Her journey moves from solitary practice sessions to crowded venues, where small mistakes become lessons and courage grows with every stage. The character faces worries about fitting in, keeping pace with friends, and sharing the spotlight, yet she perseveres, finds her voice, and inspires others with steadfast friendship and determination.
