Nene Sonono is president of the financially troubled eroge company Flower. Despite her elementary school-aged appearance, she is actually in her thirties. Following the commercial failure of Flower's first game and facing dire financial straits, she hires Mochizuki Tomoya, an avid eroge player lacking professional development experience, as a strategic gamble. She believed his genre expertise was essential, as none of her existing employees had played dating sims, contributing to their initial lack of insight.

Her management style involves unconventional actions like organizing company events and confronting financial pressures directly. She visibly stresses over the company's inability to pay salaries and copes by drinking alcohol with Tomoya during late-night office sessions, highlighting her vulnerability under the weight of leadership.

Nene is involved in critical company decisions, though she receives less narrative focus than other main characters. Her role centers on steering the company through its recovery, culminating in the successful release of their second game. She then participates in the company's celebratory trip to an onsen resort. Her appearance and involvement are not detailed in official spin-offs, sequels, or media beyond the original OVA series.
