Two manga are closing the book this December — one a long-running institution, the other barely out of the gate.

Seraph of the End, the vampire apocalypse series that debuted in 2012, will end on December 4. The finale caps a run of roughly fourteen years, closing out one of the more durable dark-fantasy titles of its era.

On the other end of the longevity spectrum, Watari Sakou's spy romance Honey Trap Method ends on December 1. The series launched in March of this year, meaning it will wrap after only about nine months of serialization — a short run even by the standards of fast-moving magazine schedules.

The near-simultaneous endings make for a study in contrast: a decade-plus epic reaching a planned conclusion alongside a newcomer bowing out within its first year. December just got a little heavier for final-chapter readers.
