Aka Manto

[1] If an individual attempts to outsmart Aka Manto by asking for a different color of paper, cloak, or cape, it has been said that they will be dragged to an underworld or hell as a result.

[9] In some versions, choosing a "yellow" paper, cloak or cape will result in the occupant's head being forced into the toilet, sometimes until they drown.

[1] Author and folklorist Matthew Meyer has stated that the Aka Manto has been recorded as a schoolyard rumor dating back as early as the 1930s.

[11] The 2003 video game Castlevania: Aria of Sorrow features an enemy known as "Killer Mantle", which may have been based on the Aka Manto legend.

[12] The Legend of Zelda franchise has several variations on the Aka Manto, in the games Oracle of Ages, Skyward Sword, and Majora's Mask.

It serves mostly the same purpose in all three games, in which it is found in a lavatory at night, and will ask for paper (or simply mutter threatening phrases at the player in Oracle of Ages.)

In Skyward Sword, it can be found in the Knight Academy bathroom at night and will ask for paper, which the player can acquire through various side quests.
