Fenrir

This character embodies the monstrous wolf Fenrisulfr, the giant bound by the gods, who currently appears as a small black dog. He possesses a complex dynamic with Loki, displaying an almost frightening protective instinct, especially when Loki is threatened. Fenrir is known for his boisterous nature, often being bossy and crude toward Yamino, though he instantly shifts to extreme affection upon Loki's arrival. His vocalizations are unique, sounding like both barking and singing to humans, despite the gods understanding his true words.
