Kuro

Kuro stands as the leader of the Hell Wolf clan, dwelling within the feared "Forest of Death," and holds the distinction of being the very first companion the protagonist Hinoki encountered upon arriving in another world. Once rescued and taken in by Hinoki during a desperate moment, Kuro subsequently led his mate Shiro and their descendants to settle permanently in the Great Tree Village. Despite possessing formidable combat prowess, he displays a gentle, domestic-dog-like demeanor in Hinoki's presence, dedicating himself to patrolling and guarding the village's surroundings as one of Hinoki's most trusted and faithful subordinates.
