Laika, a middle-aged man working as a support member in a rookie adventurer guild, quietly used his unique skills to aid his teammates from the shadows—greatly contributing to their growth and quest success. But the young adventurers, oblivious to his efforts, start viewing him as dead weight. Being the only “old man” among them, Laika is unfairly criticized and ultimately kicked out of the guild. What they didn’t know… is that Laika was once a member of the legendary Hero’s Party that defeated the Demon Lord ten years ago. Now, as the once-slumbering hero awakens and reunites with his scattered comrades, a brand-new journey begins.
