Powerful weapons and magic always come with negative effects—demerits.

However, the party members, who did not believe this fact, mistakenly thought everything was due to their own power and banished Fall. At a loss, Fall goes on an adventure alone to make a living, but unfortunately encounters a dragon. He takes a breath attack and expects immediate death—or so he thought, but he was unhurt!? By continuously bearing debuffs, Fall had obtained the strongest body! An encounter with a beautiful girl hero who cannot pull out the holy sword, battles with the Demon Lord's army... amid the turbulence, Fall grows even further. Meanwhile, the party members continue to fail their requests in the face of unfamiliar debuffs...
