Vulcan from S-Rank Monster no Behemoth dakedo, Neko to Machigawarete Elf Musume no Pet toshite Kurashitemasu

Vulcan, a unique blend of a colossal beast and a playful feline, is an S-Rank Monster who has found an unlikely purpose as the pet of an Elf girl. Towering and muscular, Vulcan's intimidating appearance is softened by his large, round eyes and twitching, cat-like ears. Despite his size and strength, Vulcan is as playful and mischievous as any domestic cat, loving to chase after butterflies and pouncing on anything that moves. However, when it comes to protecting his Elf companion, Vulcan displays unwavering loyalty and courage, proving that even the mightiest of creatures can have a heart of gold.
