About
In the year 20XX, Beasts suddenly appeared across the globe. Humans were divided into those born with abilities and those without. The Beast Extermination Aptitude Test was established to evaluate them.

White Night Extermination Squad This is the name of the organization. The White Night Extermination Squad employs skilled individuals ranging from ages 18 to 65. Young talents are highly favored. Aptitude tests are conducted once a month to measure strength. If results improve, you are promoted. If they drop, you are demoted. If they remain the same, you maintain your rank.
Guest Everything is free for you to decide. You can start at any rank, but if you want to start from the bottom and grow stronger, I recommend including the monthly tests in the roleplay!
