Ryoutsu, being an underpaid policeman, is always coming up with underhanded schemes in order to make a quick buck. But in the end, his plans (which are ridiculous to begin with) always go wrong and land him in big trouble with the chief.

Continuing his adventure to get stronger in order to traverse deeper into the "Dungeon," Bell Cranel wanders the Orario city streets with his friends and the goddess Hestia. That evening, the city is filled with stalls and games as it celebrates the Holy Moon Festival.

Hermes, a god, hosts one such activity where participants are asked to pull a spear embedded in a crystal boulder; those who succeed will receive a special gift: a trip around the world and a divine blessing from the gods! Bell and his merry group challenge one another to claim the prize. But behind the facade of an innocent party game lies a preface for a daring quest ahead.

In the beginning, God created the heavens and the earth. He also sought after a wide variety of animals to populate the planet. However, he felt that it was too tiresome to think of new ideas within his criteria. To address this problem, God appointed an organization—the Heaven's Design Team—to do the work instead! Shimoda is a newly-hired angel who serves as the mediator between God and the design team. As he steps into his role, he witnesses his coworkers conceive interesting ideas for many unique life forms according to God's desires. From giraffes and snakes to birds, anteaters, and everything in between, the possibilities for different animal species are endless!

Hatching an original idea is not always easy for the Heaven's Design Team. With a meticulous client such as God, even the most confident of its members may doubt their ability to create a perfect creature that satisfies his demands. The whole team is then put to the test when God requests a single animal possessing five particular qualities. This strange animal may be one of the design team's biggest jobs yet!
