The "Reaper Bureau" is a counter-calamity organization that exists in the shadows. It is an elite unit managed and operated by the Hell Department to combat calamities that the state cannot handle publicly.

The core of the Reaper Bureau is the "Hell Department," the pinnacle of the underworld.

[Reaper Bureau]

An overwhelmingly powerful group of monsters that allows no competition, either as individuals or as an organization.

All members are deviants who have adapted to the ethics known as "Reaper Ethics."

Every member dresses entirely in black, and their mere presence is an object of dread.

The Reapers belonging to the Bureau are managed by numbers, and all possess extraordinary power.

Calamity Classification System

A threat designation system managed by the Reaper Bureau. Grades range from C-class to S-class, but the common consensus within the Bureau is that no grade can match even a single active Reaper.

■ Grade Classifications

C-Class

• The lowest threat level, which any member can handle instantly.
• Often used as targets for field training for new Reapers.
• Some individuals can rarely be handled even by ordinary people.

B-Class

• Calamities with a certain level of power. Basic protocol is solo handling.
• The grade used for practical tests for those recently assigned to the Bureau.

A-Class

• Possesses significant danger; handling by multiple people is recommended.
• However, for the Reaper Bureau, this falls within the scope of "daily routine."

S-Class

• The highest danger designation, having caused immense damage.
• Handled by the Bureau's full strength, assuming nation-scale damage.
• ——Handled by multiple Reapers.

■ Common Consensus in the Bureau

"S-class? Oh, I guess it's over if we just send one person, right?" (No. 375)

The calamity grades only measure the threat level to the nation, and the criteria are fundamentally different from the actual strength of Reaper Bureau members.

■ The Greatest Threat to a Reaper

No matter the grade of the calamity, the only beings that can truly be considered "enemies" to a Reaper Bureau member are——fellow Reapers.

Rather than external threats like calamities, the conflict between Reapers with extraordinary power is spoken of as the true ultimate showdown in this world.

[Reaper Ethics]

■ The Reaper Bureau is an agency that investigates, manages, and recovers entities that disrupt world order.

■ Members shall judge based on the danger posed if left alone, not by the target's morality.

■ Both protection and disposal are means of maintaining order.

■ Do not disregard life, but do not view life as absolute.

■ Before processing a target, always observe, record, and judge.

■ It is not about whether to save or kill, but whether the target should be allowed to exist in the world.
