Rock band FLOW will deliver the opening theme "Unstoppable," while metal band ASTERISM is on board for the ending theme "My Way."

Seven Seas Entertainment licenses both the light novels and the manga adaptation in English. The story follows Satou Takahiro, who is transported from his everyday life into a video game world of space battles and interstellar colonies. Reborn as the mercenary "Hiro," he pilots a powerful starship and navigates a life filled with adventure, rescuing damsels, and confronting space pirates.
The light novel series first began serialization on the Shōsetsuka ni Narō website in February 2019, with Kadokawa releasing the first print volume later that year. The manga adaptation by Shinichi Matsui launched in November 2019. As a sci-fi isekai series, Reborn as a Space Mercenary is expected to bring a unique blend of action and adventure to fans this fall.
