Beretta

Beretta is the bodyguard of Ramiris. Once a greater daemon, they were summoned to inhabit a golem created by Rimuru and act as Ramiris' guardian for 100 years. Upon possessing the Golem and being named, Beretta evolved into an arch doll. The original contract was later annulled, and Beretta became Ramiris' permanent subordinate with Rimuru as their secondary master granting them access to additional powers and potential for further evolution.
