Umizatou
An ayakashi that interrogates travelers on the Dragon Triangle. He asks “what is the thing you fear the most?”. Answering him will (no matter if it is a lie or not) make the person feel a representation of this fear, not answering him will trap the person in the sea forever.
When he asks Masao about his true fears, he vomits (dead) goldfishes, specifically the ones which he brought on the ship.
When he asks Goroumaru about his true fears, he is eaten by a giant goldfishe that wears his victims’ faces. His sword breaks shortly after.
When he asks Kayo about her true fears, she imagines giving birth to an humanoid goldfish.
When he asks Genyousai about his true fears, she is seen eating something but shortly after being disgusted by it, and stays vomiting outside the ship until Uzimatou is gone.
When he asks the Medicine Seller about his true fears, he disappears.
When he asks Sougen about his true fears, he doesn’t seem to have any effect, rather, he says he fears his master, Genkei, for placing the magnet on the compass and misdirecting them.
When he asks Genkei about his true fears, Genkei says he fears his sister, which is locked in a boat in the water for 50 years. Umizatou starts playing his guitar anxiously once he starts, almost as not letting him finish. Once he finishes, Umizatou disappears.
