Mōri Terumoto
The 15th "shōgun" of the Ashikaga shogunate, Ashikaga Yoshiaki had a falling out with Oda Nobunaga in 1576 and invited Mōri Terumoto to join the 2nd Oda Encirclement Plan (第2次信長包囲網). The alliance consisted of Ashikaga Yoshiaki, Mōri Terumoto, Uesugi Kenshin, Takeda Katsuyori and the Ishiyama Hongan-ji monks. The allies really didn't have too much success against the powerful Oda armies. The significant event here is the formation of all these powerful men, who were oftentimes not the best of friends. That same year (1576) at the First Battle of Kizugawaguchi, Kobayakawa Takakage led the Mōri naval forces with Murakami Takeyoshi. The Mōri navy successfully thwarted an Oda blockade of the Ishiyama Honganji led by Kuki Yoshitaka.
