Behemoth's Pet

Aria, an elven adventurer, finds a cute little beast snuggling against her ample chest. She decides to take it in as a pet and names it Tama. At first glance, it seems like an ordinary cat—but Aria doesn’t realize that Tama was once a knight. His true form isn’t a harmless feline, but a young Behemoth, one of the most powerful monsters in existence.
