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.

When Kazuma Satou died, he was given two choices: pass on to heaven or be revived in a fantasy world. After choosing the new world, the goddess Aqua tasked him with defeating the Demon King, and let him choose any weapon to aid him. Unfortunately, Kazuma chose to bring Aqua herself and has regretted the decision ever since then.
 
Not only is he stuck with a useless deity turned party archpriest, the pair also has to make enough money for living expenses. To add to their problems, their group continued to grow as more problematic adventurers joined their ranks. Their token spellcaster, Megumin, is an explosion magic specialist who can only cast one spell once per day and refuses to learn anything else. There is also their stalwart crusader, Lalatina "Darkness" Dustiness Ford, a helpless masochist who makes Kazuma look pure in comparison.
 
Kono Subarashii Sekai ni Shukufuku wo! 2 continues to follow Kazuma and the rest of his party through countless more adventures as they struggle to earn money and have to deal with one another's problematic personalities. However, things rarely go as planned, and they are often sidetracked by their own idiotic tendencies.

Game loving shut-in Kazuma Sato's life as a young schoolboy in Japan abruptly comes to an early end...or at least it was supposed to. When he opens his eyes, though, he sees a beautiful goddess that offers him a once in an after-lifetime chance to be reborn in a parallel world. The catch is that the world is violent and threatened by a growing evil! Fortunately, he can choose any one thing to bring with him. So he chooses the goddess, Aqua! And so his adventure with his gorgeous companion begins--if he could just get enough money and food to survive, keep his goddess out of trouble, and avoid grabbing the attention of the Demon King's army!
