Beheneko: The Elf-Girl's Cat is Secretly an S-Ranked Monster!

A fallen knight wakes in a small body that looks like a kitten. In truth he is a behemoth, a top class monster. An elf named Aria finds him, names him Tama, and takes him home in a city built around dungeons and labyrinths. He keeps speech and power hidden and shadows her on quests while she believes he is a helpful elemental cat. Rumors about imperial summons and legendary figures pull Aria’s party from local dives to formal visits, then into the depths after reports that a member of the Demonic Four has stirred. Knights and officials watch the group, some for protection and some to study the cat that never seems afraid. Tama learns to shape strength without breaking his cover, turns battles that should be lost, and guides Aria through traps, living corridors, and rival claims on artifacts. Each win tightens the circle around his secret while the path ahead leads toward older enemies and a truth that cannot stay hidden forever.
