Sengoku Basara: Setonai no Gekitotsu! Hi wo Fuku Umi no Daiyousai - Fugaku!!

Maeda Toshiie and Matsu travel to Shikoku with demands issued in Nobunaga's name for Chousokabe Motochika. Motochika refuses to submit and instead urges Toshiie to turn against the ruler he serves, forcing the Maeda pair to confront the growing cost of remaining loyal to Nobunaga.

Elsewhere, Keiji tries to persuade Mouri Motonari to join the resistance and is imprisoned for his efforts. Tension between Motonari and Motochika then pushes the two powerful western leaders toward conflict with each other, threatening to waste forces that could otherwise stand against Nobunaga while the massive sea fortress Fugaku looms over their confrontation.
