About this AUEdit
Spawning from fanart, this AU places the Big Four, and other such characters in the fandom, as characters from Spirited Away.
The Big FourEdit
For the Hijack pairing, he's cast a male version of Chihiro or as Haku with Toothless as his dragon form. He can even be cast as a male Lin, the bathhouse worker that helps the trapped human.
Fans have most commonly cast Jack as the homeless river spirit, Haku as he helps a young human survive the witch of the bathhouse (for spirits) clutches until he could return the Ogino family home. Jack is also portrayed as the lonely masked monster/spirit No Face. Being a spirit himself also means that he can be one of the spirits that "baths" at the bathhouse.
Rapunzel is portrayed as Chihiro Ogino (also known as Sen when the witch changed her name), as she works for Gothel (as Yubaba) so she wouldn't turn her into a pig and until Gothel's apprentice comes back to set her free. She is sometimes portrayed as a female Haku for the Meripunzel pairing.
Hiro can be cast as a male Chihiro, with Baymax or Yokai as the lonely monster/spirit No-Face and Mochi as Yubaba's baby son, Bou in mouse/animal form.
Young Gothel is cast as Yubaba, the Witch that owns the Bathhouse, while old Gothel plays her twin (kinder) sister, Zeniba (also known as Granny to Chihiro).
North is the six armed boiler man, Kamaji. As he helps the witch's apprentice and gets one of the bathhouse workers (that brings him and his little workers food) to keep a young human child safe in their world. His Elves can serve as the smell, soot creatures; that help him to feed the boiler's flames while he makes herbal remedies for the bathes.
When Jack is cast as Haku, Jamie is portrayed as a male, younger Chihiro. As both characters befriended spirits and helped them when they were in danger.
