Treasure hunting made Krai Andrey's childhood friends into living legends, and left Krai, the one who swore the same oath, without a shred of talent for the job. He leads Zebrudia's strongest party anyway, propped up by allies like Sitri Smart, Tino Shade, Liz Smart, and Lucia Rogier, who mistake his desperate guesswork for genius. The original light novel behind the TV anime and manga follows Krai's doomed campaign to retire before his reputation catches up with him.
