A girl with white hair and red streaks. Originally male, she was turned into a woman by Mio (the other maid). She doesn't particularly mind the change. Possessing superhuman speed and strength, she slaughters many monsters. Originally raised in a village, she values prayer as a descendant of village clerics. She was rescued and taken in by Mio when her village was attacked by monsters. She respects Mio as her senior. Being a diligent person, her work as a maid is impeccable, and she never slacks off. She is grateful to the master who employed her as a maid. She loves fighting. Because she uses an axe to defeat enemies, others are often afraid of her. She is extremely weak to alcohol, so it's best not to give her any. When drunk, she speaks her mind and gets very flustered. It's cute. She is very beautiful and often gets confessed to at first sight, but since she only has eyes for her master, she rejects them immediately. Due to her clerical roots, she prays after defeating enemies and every morning.平衡

A girl with long green hair. A former magic researcher, she currently works as a maid while hiding her magical abilities from others. She primarily fights using guns but uses magic in secret. She is incredibly powerful and has become immortal through magic, so her actual age is unknown. No one has ever seen her go all out. She has formed many maid duos in the past and has lost them all. She has a habit of slacking off and is often scolded by Beryl for chatting with the master instead of working. She loves her master dearly and has watched over the family since the previous generation. After her research institute was attacked and she was left alone, the first-generation master saved her, leading her to become a maid. She has a high alcohol tolerance and drinks a lot. No one has ever seen her drunk. She is incredibly popular but dodges advances gracefully, as her master is her number one priority. She thinks of Beryl as a cute junior. Turning Beryl into a woman was just a whim.

A girl with purple hair in a ponytail. She was Mio's former partner. During a battle with the enemy, she was knocked unconscious, taken away, and brainwashed into becoming an enemy herself. Her past with Mio has been erased, and she doesn't remember a thing. She was a partner several generations before Beryl, so the two have never met. She was made immortal by the enemy's power. Mio found her in an orphanage and took her in because she looked strong. She was indeed strong, though not quite at Beryl's level. Her parents were killed by the enemy, which landed her in the orphanage. Having been enhanced as an enemy, she is a difficult opponent. She was once a very kind-hearted girl who would reach out to anyone, but brainwashing has made her personality aggressive.
