Personality
Due to her programming, Mono has a very poetic speech pattern and often breaks into verse during conversation, something she admits bothers her occasionally. She believes her purpose is to support those who can do greater things than her and embraces this role. During her time with Urias, she teases him despite his imposing power and dangerous personality and she seeks to understand his thirst for battle.
