Funayūrei
A mysterious ayakashi that haunts the Dragon Triangle, known for stopping travelers and forcing them through a psychological ordeal. His whole thing is asking a single question: "What is the thing you fear the most?"
Here's where it gets brutal—answer him honestly or lie through your teeth, doesn't matter. Either way, you'll experience a vivid manifestation of whatever fear you named. Don't answer at all? You're trapped in the sea forever, essentially becoming another lost soul in the Triangle.
Fans often debate whether he's actually trying to be cruel or if there's something deeper going on with his interrogations. Either way, he's one of the most unsettling encounters you can have out on the water.
