As the story opens, Masamori was not present. While cleaning up the damage caused by Yomi Kasuga and Yoki, Shigemori reveals that Masamori was Chief of The Shadow Organization's Task Force. Sometime later, Masamori meets with Yomi, who is (at the time) scheduled to be executed for interfering with Karasumori, a forbidden offense in their organization. Yomi accuses Masamori of having encouraged her to go to the site, but Masamori denies this, and blackmails her into working for him by threatening to destroy Yoki.
