Muromi-san

One day, Takurō was fishing at the pier as usual, when he caught the big one: A mermaid. However, contrary to her legendary appearance, she's head-over-heels for "Takkun", uses a shell-phone, and is instinctively afraid of birds and seals due to their love of fish. Since the time he met Muromi, he's met Leviathan, a yeti, a harpie, a kappa, and more. It seems his relationship with the spunky mermaid gets weirder by the day.

Super sadly this is the only one of its kind
