Snee evolves from Chansin when fused with a Cursed Blade.
Snee is a humanoid Yo-kai with glowing golden yellow eyes and a stoic expression on his eyes. He wears a large kasa hat with several talisman sticked to the edges and a light teal wisp on the top, a ragged cloak in shades of purple, dull magenta, and black, and white wrappings on his right arm. Snee is seen wielding the Cursed Blade, which has a artic teal jagged blade and black hilt.
Because his blade has cursed him, Snee searches for blood. In the manga, he searches for blood because he has anemia. He can be very dangerous.
The blade he carries makes him crave blood. He sneaks up on people to get some.

"Snee" is a Dutch word meaning "cut, slash, slice".
In German, "Fiesa" is derived from fies (nasty, underhanded).
Snee's Japanese name, Muramasa, refers to Muramasa Senji, a legendary swordsmith of the Muromachi period who crafted beautiful, amazingly sharp katana blades, which were named after him. However, he was said to be a violent, unstable individual, attributes which his works allegedly inherited. The likely truth of the matter is that the shogun Tokugawa Ieyasu was said to have lost many friends and dear ones to Muramasa owners, and even wounded himself badly by accident when handling one: for that reason he forbade carrying any sword forged by Muramasa, which fueled the rumors and legends around them. They were said to be cursed, grim blades, that once drawn could not be sheathed again until they had tasted blood, and so unnaturally sharp that even if placed down on the surface of a river they would slice all leaves and fish floating through.
Muramasa Senji was said to be a contemporary and rival of the swordsmith Gorou Nyuudo Masamume (see Sheen#Trivia), but this is untrue as Muramasa lived much later than him.
