Sympathetic to his predicament, Satoru befriends him, promising to assist in destroying the seal. He then stumbles upon the sealed Catastrophe-level monster "Storm Dragon" Veldora who had been sealed away for the past 300 years for devastating a town to ashes. In doing so, he acquires newfound skills-notably, the power to devour anything and mimic its appearance and abilities. When Satoru regains consciousness, he discovers that he has reincarnated as a goop of slime in an unfamiliar realm. However, while succumbing to his injuries, a peculiar voice echoes in his mind, and recites a bunch of commands which the dying man cannot make sense of.

In the midst of a casual encounter with his colleague, he falls victim to a random assailant on the streets and is stabbed. Thirty-seven-year-old Satoru Mikami is a typical corporate worker, who is perfectly content with his monotonous lifestyle in Tokyo, other than failing to nail down a girlfriend even once throughout his life.
