I don't agree with using Zerg. This is not a meta RPG isekai full of direct references and dedicated to exploring the tropes of the genre, therefore "adjusting" the names to make them sound familiar diminishes from the otherworldliness of the setting. Translating Zooku for Zerg would make sense...
So much wasted potential in a manga that started out being about unregulated sex work, systemic poverty in capitalist societies and the commoditization of youth. 😔
