The notorious rookie team known as the Calamity Angels.

Originally, this group was called the "Cutie Angels," but after constantly delivering to the wrong addresses, missing deadlines, and causing trouble wherever they went, they earned themselves the nickname"Calamity Angels"—the angels who bring disaster.

With rookie leader Yuri at the helm, can this team of misfits turn things around and become one of the top delivery squads?

The guild manages the delivery of goods, people, and information throughout the land. Couriers receive and fulfill requests through the guild.

In a world overrun by fierce monsters, venturing beyond the city's protective walls is extremely dangerous. That's why all deliveries to distant locations are handled by guild-affiliated delivery teams.

A mysterious power bestowed by the gods in ancient times. It's an energy that springs from the hearts of living beings, generated by people's feelings or thoughts. This energy is used to support the city's infrastructure and maintain barriers that keep monsters at bay.

A research institute within the guild dedicated to preserving ancient ruins and collecting ancient artifacts. Since these artifacts can be powered by Omoi Power, they are used to protect people and enrich their lives.

A group of bandit-like outlaws who operate outside the city, commonly known as the Troublemakers. They're a dangerous bunch who attack delivery teams and loot ancient ruins—quite the threat for an unprepared team.

A unique type of monster that feeds on Omoi Power, the emotions imbued in packages. Because they target these emotional energies, they're regarded as the arch-enemies of delivery workers. When a package loses its Omoi Power, it darkens and falls apart. That's why safeguarding packages is an important part of a courier's job.
