KONOSUBA -God's blessing on this wonderful world! 2: God's Blessings on These Wonderful Works of Art!

Overview

An unaired episode bundled with the 12th volume of the light novel. After returning from his trip to Arcanretia, Kazuma is living life without a care in the world, thanks to his debts being all paid off by the reward money he earned from eliminating one of the Devil King's generals, Hans. One day, a rookie adventurer named Ran comes up to him in the Guild Hall asking for a handshake. She's apparently become a fan of Kazuma after his consecutive defeat of the Devil King's generals! This puts him in an amazing mood, but it's not long before the Guild receptionist Luna appears, asking him to take on a quest to eliminate a golem. Wanting to look good in front of a fan, Kazuma ends up accepting, and heads towards ancient ruins with Aqua, Megumin, and Darkness in tow. (Source: Crunchyroll)
