Complete listed story — includes the ending

1. Thanks to Them

Luz and her friends spend the next few months in the Human Realm, trying to find a way back to the Boiling Isles. One day, Amity, Willow, Gus, Hunter, and Vee eventually discover a scroll in the floorboard of the abandoned house and learn that it is a map of a place where Titan's Blood is being kept. Meanwhile, Hunter continues to have visions of Belos and is unknowingly possessed by him. At the town's annual Halloween Festival, the group learns that Philip Wittebane had a brother named Caleb who met and fell in love with a witch named Evelyn. Posing as Hunter, Belos tricks Luz into helping him find the Titan's Blood as Camila and Luz's friends arrive to help Hunter and Luz. Hunter overcomes Belos' control but becomes seriously injured as a result. Belos opens a portal to the Demon Realm and escapes, while Flapjack sacrifices himself to revive Hunter. After that, Luz explains to others about how she helped Belos meet the Collector, so the group intends to stop Belos. Camila announces that she will join them as well while Vee stays behind to keep up appearances.

2. For the Future

Luz and the group arrive in the Boiling Isles to discover that the Collector has turned the residents into puppets for his games, with the exception of King, Eda, Odalia, and Lilith. King does not want to hurt the Collector due to his childish innocence, but Belos takes over Raine's puppet to manipulate the Collector into thinking that everyone is against him. Luz, Camila, and their friends run into the surviving Hexside students who have turned the school into a new society. However, Boscha rules the school with an iron fist and refuses to help the gang. It is later revealed that a disguised Kikimora has influenced Boscha who is still angered at Amity for leaving their friend group. Hunter and Gus aid Willow, helping her to express her suppressed feelings, while Camila helps Luz overcome her anxiety. After convincing the whole school including Boscha to battle Kikimora, the entire group goes to the Collector's castle via the teleportation spell as Luz's palisman finally hatches into a "snake shifter" which she calls Stringbean, much to everyone's delight.

3. Watching and Dreaming

The Collector captures Luz, Eda, and King to force them to play his games, while Belos takes over the Titan's heart to use its powers to destroy the Boiling Isles. After befriending the Collector, Luz tries to protect him from Belos' blasts but is killed and sent to an in-between dimension where she meets King's father, the Titan. He imbues Luz with his remaining powers to return and stop Belos, while Camila and Luz's friends escape from their trapped puppet forms and protect the residents with the Collector's help. Luz successfully removes Belos from the Titan's heart who tries to feign reformation, but is stomped out of existence by Eda, Raine, and King. Everyone is happily reunited, but Luz discovers that due to the Titan finally passing on, the glyphs no longer work. Four years later, Luz has graduated high school and has been accepted into a college at the Boiling Isles, where life has changed for the better for everyone. Luz returns and is surprised by a belated quinceañera, with King revealing that he can empower his own glyphs now, and a light show is presented by the Collector.
