 While en route, the boat that Masachika rode in came under distress, eventually reaching shore in the Ōuchi's main territory of Nagato Province.Yoshioki captured his father and had him commit "seppuku", most likely as retribution for the alleged poisoning of Yoshisuke.During this turn of events, Hosokawa Masamoto operated behind the scenes, fearing the expansion of the Ōuchi influence and their connection to the deposed "shōgun", Ashikaga Yoshitada (formerly under the name Yoshiki), who lived in exile in the northern provinces.
