Malevolent Spirits: Mononogatari manga volume 3 features story and art by Onigunsou.

Word of Hyoma’s residence in the Nagatsuki household has spread throughout Kyoto, and the larger tsukumogami groups aren’t happy about it. After all, no one has been allowed to get near Botan for years—human or tsukumogami. When Hyoma goes to pay his respects to a local Saenome clan, they ask him to get rid of Botan and her six tsukumogami once and for all. If Hyoma refuses, he might have an all-out clan war on his hands. His only option is to take on the entire clan by himself!
