Lucifer and the Biscuit Hammer Manga Omnibus 4 collects volumes 7-8 and features story and art by Satoshi Mizukami.

The Beast Knights are still reeling from the death of one of their own, but there's no time to rest - Animus's multi-bodied tenth golem keeps coming back from every defeat, and each time its assault is more ferocious than the last. Even with the power of two Mythical Beast Knights, and with Samidare throwing herself back into the fray, how can the Beast Knights hope to defeat an enemy that constantly grows stronger?
