Tortus

Tortus is a character mentioned in The Legend of Zelda: Majora's Mask. He is the deceased father of Anju. His name is mentioned often because Anju's Grandmother, who is apparentally senile, often calls Anju and Link by the name of Tortus.

Biography
Anju mentions that when Tortus was alive, the Stock Pot Inn was a cafeteria run by him. After he passed away, however, his wife turned the building into an inn.

Following his death, his mother started to become senile. During the events of Majora's Mask, she often calls Anju and others by the name of Tortus. Anju constantly reminds her grandmother that Tortus is no longer alive, but she never appears to fully understand. There are a few hints in the game, however, that suggest that Anju's Grandomther is faking senility. The main source of this theory is some hints in her journal that may lead the player to believe that her mentioning Tortus may be her way of maintaining this illusion.
