The supernatural thriller Ruby on the Cake: Feast of the Man-Eating Witches (Ruby on the Cake: Hitokui Majo no Bansan-kai) has concluded its run. The final chapter appeared in the September issue of Square Enix’s Monthly Big Gangan magazine, which arrived on Tuesday. Readers looking to complete their collection can anticipate the fourth and final compiled volume hitting shelves on October 23.

Created by Miki Morinaga, the series debuted on the Manga UP! platform in April 2024. The story centers on Ruby Blood, a prodigy operative within MI6’s specialized 'RED' unit dedicated to purging London of humanoid, man-eating witches. Morinaga balances the high-stakes, eat-or-be-eaten premise with Ruby’s personal life, depicting her as a teenager who enjoys domestic comforts and her father’s cooking when not on duty.

The manga’s narrative trajectory shifts significantly following a fateful incident on Christmas night, which serves as the primary catalyst for the series' suspense-driven plot. With the third volume having released last December, the upcoming fourth volume will wrap up the saga of Ruby’s battle against the witch population.
