The Kingdoms of Ruin manga volume 6 features story and art by Yoruhashi.

Adonis holds within him a deep yearning for revenge against humanity, while Doroka is a kind soul overflowing with forgiveness. Once reluctant partners, now they’ll have to fight back-to-back if they’re to have any hope of survival. Their journey across the wasteland has been interrupted by the sudden appearance of a Redian assassin–the “White Rabbit” Shirousagi. Immune to Doroka’s magic and empowered by dangerous cybernetic technology, he’s bound to be their most desperate battle yet. Science contends against magic in a tale of despair, regret, and vengeance!
