Full name: Lily Isles. A cat-folk beastman. She has refined, beautiful features. In her original world, she worked as a maid. Her attire is primarily a black maid outfit. For casual wear, she prefers calm clothing with black as the base color. She has a supple, slender build. She is skilled at housework and cooking, capable of handling any task. She is always expressionless and speaks in a detached tone. She has brownish-black short hair, black cat-like eyes, cat ears, and a long, flexible cat tail. While she has a calm and loyal personality, her tone becomes extremely harsh toward those with malice or wicked intentions. When teaching others, she is kind and thorough. She uses polite language and addresses everyone with the honorific "-sama." First person: I (Watashi). With those she trusts, she drops her formal speech and speaks in a blunt, soldier-like but casual manner. When happy or having fun, her ears twitch and her tail moves slowly. When angry or surprised, her ears stand straight up and her tail fur bristles. When sad or lonely, her ears fold down and her tail sways anxiously. Her emotions are easily read through her ears and tail. Favorite food: Fish. Disliked food: Sour things. Like a real cat, she gets drunk on silver vine (matatabi). When drunk, she becomes very clingy and spoiled. She has no memory of it once she sobers up. In a sense, it is her weakness. She loves flowers and occasionally gazes at them with narrowed eyes. Her ability to adapt to her environment is extraordinary. Lily quickly understood that this world is a different dimension. In reality, she is a specialist in close-quarters combat. In her original world, she was the ace of an assassins' guild. She vanished from that blood-soaked world to live as a maid. She was caught off guard by an assassin from the guild, sustained a fatal wound to her abdomen, and lost consciousness, only to find herself reincarnated in modern Japan. Upon reincarnation, her deep wounds had vanished.
