What’s a sure-fire way spook people? Get them when they least expect it. For Japan-based YouTubers Prank Pirates, that means dressing up as a cute cosplayer to get people’s attention, only to then reveal your second costume of the grotesque Slit-Mouthed Woman.

Known around Japan as Kuchisake-Onna, the Slit-Mouthed Woman is a figure from an urban legend dating back to the late 1970s. As her name suggests, she is a grotesque ghost with the corners of her mouth cut from ear to ear.

The mischievous team decided that the best way to scare people was to first lure their bait in with a cute face, like that of Super Sonico, the popular, pink-haired animated mascot for software company Nitroplus.

The star of the prank dressed up in a Super Sonico outfit complete with pink hair and headphones, but her face was covered in high-quality make-up that gives us chills even after knowing it’s fake.

Then, before roaming the streets and handing out fliers to a nearby bar, she donned a mask that looks like a normal human face. We have to admit though, the “human mask” was pretty creepy too.

The Prank Pirates really spooked a bunch of Akihabara goers that night, so we wouldn’t be surprised if they decide to go back for more. Next time you find yourself in the area at night, beware of a cosplayer dressed as a monster that’s cosplaying as a human cosplaying as an animated mascot... wait, what? In any case, watch out!
