The Anime Supremacy! The novel was released in October 2017. Also here is a quick description of the story by Kodansha USA Publishing:

Japanese animation—the globally acclaimed, family-friendly theatrical features are the exception rather than the rule for a TV-oriented industry that has been pushed into late-night slots in an era of fragmented audiences. When only three titles among fifty might turn a profit, topping the charts is hardly an overambitious aim. Yet as three women, a producer, a director, and an animator, survive in a business infamous for its murderous schedules, demoralizing compromises, and incorrigible men, moments of uplift emerge against all odds—and how. More than just a window into an entertainment niche, here’s a kickass ode to working.
