A Classic we never got outside Japan where you land on a Innsmouth-esque Island and have to fight Lovecraftian Monsters, Deep One Cultists, and other shenanigans. Also known as Mark of the Mermaid in English. Has branching paths and multiple endings, incentivizing multiple playthroughs. Horror RPGs are a rare combo despite how insanely well they can meld (See Shadow Hearts for a great example.), and quite frankly we need more of them.
