Kez

“	Sometimes numbers are part of the problem, not the solution, y'know?	”
—Kez to Min-Gi, "The Iceberg Car"

Kez is the deuteragonist and the bell companion to Ryan Akagi and Min-Gi Park throughout their journey in Book 4.

Appearance[]

Kez is a flying sentient grey concierge bell who leaves blue pixie dust behind. Her mouth forms between the sounding shell and the base.

Personality[]

Kez is kind and helpful, but also has a tendency to be dismissive about the problems she creates, most notably those with other denizens of the train. Despite this, however, she has everyone's best interests at heart, as noted with her interactions with Jeremy, when she helps him sort out his issues and gets him off the train. She also seemingly abandons Ryan and Min-Gi in "The Old West Car", only to return and save them before they are executed, further cementing her tendency to help people in whatever strange manner she deems fit.

Powers and Abilities[]

Besides the power of flight, Kez can make hand gestures with her pixie dust, store items in her mouth, and can be rung like any concierge bell.

She approaches Ryan and Min-Gi outside of the car, but the boys are perplexed by the fact they are still on the train.

She breaks herself out, leaving Ryan and Min-Gi behind. Unbeknownst to them, she asks The Cat to help her with a distraction as they are brought to trial. Her plan works and she, Ryan, and Min-Gi escape from their execution while the town is distracted with the concierge bell from the Saloon.

The Art Gallery Car[]

After entering an Art Gallery Car, Ryan and Min-Gi start chatting it up as if they were still in high school.

After looking at a mobile from a certain angle, Ryan realizes it is the exit and he and Kez get out but Min-Gi doesn’t see them. She and Ryan try and fail to get back in the car as a creature made of arms starts to lean over Min-Gi. When Ryan says he is not leaving his friend, his number reaches zero and an exit appears. He struggles with the thought of going home and leaving Min, but also wants to leave the train. Soon after his number goes back up to 115 and the exit closes.

They evade their pursuers and make it into the castle. Ryan and Min-Gi watch as Kez is chased by Judge Morpho and urge her to come inside when the drawbridge starts to close. Kez makes it in thanks to Pig Baby eating the Judge. Once inside, she introduces Ryan and Min-Gi to her roommate Morgan, and the castle starts to talk.

She manages to get Morgan to calm down. As Kez apologizes for Morgan's behavior, Ryan berates her for not realizing when she makes mistakes and leaving without fixing them. Min-Gi confirms this by saying never apologizes and Ryan asks her to leave.

After reading through Jeremy's journal, Ryan and Min-Gi learn that Jeremy spent five years with Morgan and Kez before the entries stop. After learning from the last entry he was going to have breakfast with Kez, they sneak out to find her when Morgan is asleep. She tells them how the day Jeremy left, she and him were talking about the survivors guilt he had from the car crash that killed his mother and sister. She tried to help him and eventually succeeded when his number reached zero. She explains how she called for Morgan to come, but she arrived just as Jeremy went through the exit.

However, the car starts to glitch again and a steward appears, telling the passengers the train is theirs and removing their boots before leaving and exploding in the sky.

They start to accept her apology, but Judge Morpho refuses and attacks them, only for Ryan and Morgan to swat her away. As they repair the damage, Ryan gets his exit and the two say goodbye to her before leaving.

Trivia[]

Kez's name can be derived from the KEZ radio station, which plays music from the eighties and nineties, the former being when the book she appears in takes place.
Owen Dennis joked in the Book 4 Reddit AMA that people born on the train are "recycled into the system" and their blood is used to fill Kez.^[1]
