Bakemono to Kedamono

In a forest, there lived several demons, and one ugly monster named Kavo. He lived his days in loneliness until one day he saw a middle-aged man being assaulted by three other men. Kavo tears down the attackers, saving the man, Liam. Liam is the first human to not scream and run away at the sight of Kavo – in fact, Liam seems quite eager to repay Kavo for his kindness.
