Movie
Description
Rian Stoker founded and led the Aurora Society, an organization dedicated to medical experimentation. He co-created the reanimation treatment "Absolute Salvation" with the funeral director Undertaker, asserting it could resurrect the dead and grant immortality. This project demonstrated his driving ambition and profound belief in conquering death through science. His charisma proved instrumental in establishing the Aurora Society and attracting followers such as Aleister Chamber.

Physically, Stoker possessed fair, swept-back hair and customarily wore white coats bearing the Aurora Society emblem. His personality merged significant ambition with notable cowardice; he spoke fervently about his work yet shirked responsibility for its failures. He fled the Campania when his reanimated corpses, termed Bizarre Dolls, turned violent, abandoning his own men and dismissing them as "useless" for failing to contain the threat. He was also indiscreet, readily revealing confidential information like the existence of a larger storage hold full of reanimation samples when pressured.

Before the Campania voyage, Stoker collaborated with Undertaker to supply Bizarre Dolls for covering up murders at Weston College. Edgar Redmond sought his help, resulting in a flashback scene where Stoker and Undertaker formed a contract with four students to reanimate their victims.

During the Campania's April 1889 maiden voyage, Stoker hosted an Aurora Society meeting to demonstrate Absolute Salvation. The experiment reanimated Margaret Connor, who immediately attacked attendees. As more reanimated corpses emerged from the cargo holds, Stoker repeatedly attempted to flee the ensuing chaos. Cornered by Ciel Phantomhive and his group, he disclosed that a deactivation device was located in his room. While navigating the flooding ship, he abandoned others. Later intercepted by Grim Reapers, he discovered the device missing from his room. Confronted by Undertaker in the passenger lounge, he learned the reanimation method depended entirely on Grim Reaper technology, not medical science. Undertaker dismissed his work, stating reliance on another's skills invalidated it as true medicine. A dejected Stoker sank into despair before falling to his death when the ship tilted vertically.

His surname references Bram Stoker, author of *Dracula*, sharing the same April 20 death date. In the fourth anime season, his first name appeared misspelled as "Ryan."
