Malevolent Spirits: Mononogatari manga volume 8 features story and art by Onigunsou.

The all-out attack at the Kadomori estate continues, with the paper umbrella tsukumogami seemingly having the upper hand. After the Nagatsuki dowry joins the fray, however, the paper umbrellas quickly retreat, leaving nothing but destruction in their wake—and a parting blow to Hyoma that forces him to confront his own past. In the aftermath, it's clear new allies are needed to bolster Botan's protection, but who will step up? A meeting between the Three Great Saenome Clans will determine everyone's fate!
