Alternate L. Takion functions as an author figure, having penned two books inspired by Alice in Wonderland. His driving goal is to collect the personal stories of defeated Alice Users to compile the fabled third volume, the Eternal Alice, believed to grant its completer's wishes. He presides from a separate dimensional space accessed through mirrors, distinct from the Wonderland Space of the Users' battles. Three servants accompany him there: a librarian and two young girls, both named Alice and known as the Alice Twins.

Presenting himself as Takion's successor, he shows particular interest in individuals like Aruto Kirihara for their unique abilities related to transcribing or manifesting stories. He is an antagonistic figure, relentlessly pursuing the completion of the Eternal Alice collection. The narrative uses the name "Takion" instead of Lewis Carroll, reflecting his story role.

In expanded media like spin-off games, his role extends beyond story collection. He becomes a strategic force combating entities called "riot wars" led by Jabberwocky, aiming to restore order using arcane magic. He commands loyalty from assistants Liddell, Delilah, and his designated successor Tapio, treating them with a mix of generosity and high expectation. His personality blends cunning intelligence with a fierce temper, especially when facing setbacks or incompetence. Adversaries fear him as the "Phantom Creator."

Physically, he appears as an ageless man with long silver hair tied in a ponytail, yellow eyes, and glasses. His attire typically consists of a dark green coat with gold accents, a brown collar piece, white gloves, and a beret. He wields various swords linked to arcane magic, including the "Creator Sword" and "Arcane Excalibur."

A significant aspect of his background is suffering from writer's block. This prevents his own completion of the third Alice sequel, motivating his reliance on gathering others' stories to overcome this creative stagnation.
