Malevolent Spirits: Mononogatari manga volume 7 features story and art by Onigunsou.

On their way to Tokyo, the Nagatsuki tsukumogami run into a strange roadblock—a whole group of paper umbrella tsukumogami who are after Botan. Suzuri manages to send a message to Botan in the nick of time, alerting Hyoma and the others at the Kadomori estate that a group they thought were allies are actually aligned with the paper umbrellas. A concentrated attack separates Hyoma and Botan from everyone else, and this time, Hyoma is determined to protect Botan at all costs—even if it means casting aside his chance for vengeance.
