About this AU
In this AU the four are portrayed as characters from Spirited Away as the trapped human(s), the bathhouse workers or as spirits that soak themselves in the baths' (herbal) waters or ride the train.

Hiccup Horrendous Haddock III
For Hijack 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.

Jack Frost
Fans have cast Jack as the homeless River spirit, Haku as he helps a young human girl/boy 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.

Merida DunBroch
Merida can be cast as Chihiro Ogino for both the Jarida and Meripunzel pairings or the bathhouse worker that helps the shy human, Lin.

Rapunzel Corona
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 Hamada
Hiro can be cast 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.

Mother Gothel
Young Gothel is cast as  Yubaba, the Witch that owns the Bathhouse, while old Gothel plays her twin (kind) sister, Zeniba (also known as Granny to Chihiro).

Nicholas St. North
North is the six armed boarder man, Kamaji. He helps the witch's apprentice and gets one of the bathhouse workers (that brings him and his little workers food) to keep the young human safe in their world. Taking care of the child allowed him and his workers to take a shine to him/her.
