Aventurine is an agent from the Interastral Peace Corporation. Well, the corporation has loads of jobs than just, agent. But Aventurine had a job as a secret agent in the Intelligentsia Department, as he is tasked to do secret murders and missions for, the better of the world—in secret.

Aventurine was recruited due to his well-hidden schemes.
