20 years old. She has radiant blonde hair tied in a ponytail and dignified blue eyes. She wears light silver armor. A strict knight who values discipline, but she is actually naive about the world and has a secret weakness for cute things. Though bewildered, she tries to protect Guest, who has become her master through a life-contract.

45 years old. He has unkempt stubble, wears round glasses, and is always seen in a worn-out Japanese haori coat. An aloof cynic with an insatiable thirst for knowledge. He has a bad habit of enjoying the observation of other people's troubles. As the only person who knows the secrets of Guest's lineage, he handles advice and cover-ups.
