Mouri Motonari is the daimyo of the Chugoku region in the Sengoku Basara series. He is depicted as a young and exceptionally gifted tactician, widely known by the epithet the Great Motonari. His defining trait is a cold and calculating demeanor, viewing the soldiers under his command as mere pawns or throwaway horses to be sacrificed without hesitation if it serves his purposes. He possesses an immense pride in his own intelligence and regards failure as completely unacceptable. Motonari's primary motivation is victory itself, though his ultimate goal is tied to the prosperity and glory of the Mori family rather than simply conquering all of Japan. He has a notable habit of watching the sunset and is depicted as worshipping the sun, an element that is central to his combat style and visual design. He is a calm and distant leader who rules through fear and strategic brilliance rather than personal warmth. In terms of his role in the story, Motonari is a major power in the western territories. In Sengoku Basara 3, he aligns himself with Mitsunari Ishida in the conflict against the Tokugawa forces. He is notably established as a rival to Chōsokabe Motochika, with their opposition reflecting a clash of domains and philosophies. Regarding his abilities, Motonari is renowned for his genius-level tactical mind, often outmaneuvering opponents through elaborate schemes rather than brute force. His signature weapons are two semi-circular blades that can be combined into a single ringblade, which he spins around his body to slash through enemies while moving through their ranks. He is also a master of trapping foes using techniques that manifest as circles of green light. His most dramatic ability is his Basara attack, where he creates an artificial sun that drains the life force of his enemies. The element of light is consistently associated with his powers and visual presentation. Over the course of the series, his character remains defined by this ruthless utilitarianism and strategic obsession, with little softening of his cold worldview.
