A knight who died battling evil is reborn not as a human hero but as a behemoth, a high-ranking monster. However, a baby behemoth resembles a small cat, leading to confusion. Instead of being killed, the knight is saved by an elf adventurer. Now living as a pet, he navigates this unexpected new life.
