Kurtz, Store owner Narden, Clerk Liletta, and the rest of the armor shop crew are out gathering supplies to make their naughty armor, with the help of their own in-house Demon King.
With the Demon King's incredible power, they win all their battles easily.
But on the way home, they meet a piece of armor that falls from the sky.
What do they see then...?
Welcome, travelers, to the Armor Shop for Ladies and Gentlemen.
