Mermaid Forest

An ancient legend claims that consuming mermaid flesh grants immortality. Yuta, unknowingly, ate a piece of mermaid flesh centuries ago, leading him on a quest to find a mermaid and reverse the curse. He discovers a group of mermaids raising a girl to be their food, as this is how they maintain their youth. Yuta rescues the girl, Mana, after killing the mermaids, but she has already consumed some of the cursed flesh. Despite the violence, Yuta is content with finding companionship in Mana. Trapped in a small hut, Mana finds joy in the simplest things. Together, they continue their search for more mermaids, hoping to regain their humanity.
