Description
Otani Yoshitsugu is a major figure in the Western Army in Sengoku Basara: End of Judgement, serving as the closest ally and top advisor of Ishida Mitsunari. He is a commander of considerable skill, shown early in the story when he surprises the defenders of Odawara Castle by leading his forces through an unguarded eastern gate during the siege. His appearance is immediately distinctive: his entire body is wrapped in bandages, he wears a helmet shaped like a butterfly, and he moves while seated cross-legged in meditation on a floating palanquin. The bandages reflect his condition, as he suffers from leprosy, an incurable and disfiguring illness that has caused him to be shunned for much of his life.

His personality is calm, guarded, and cryptic. He rarely raises his voice and expresses his thoughts in measured, sometimes ambiguous terms. Where Mitsunari is often consumed by an all-consuming hatred for Tokugawa Ieyasu, Yoshitsugu acts as the steadier influence, frequently taking command of the Western Army's operations when his friend's fury threatens to overwhelm their cause. Beneath his composure, however, is a deeply bitter man. Having endured illness and isolation, he wants the world to experience the same misery he has suffered, and he sees the coming conflict at Sekigahara as the perfect opportunity to make that happen. This mix of genuine loyalty and dark resentment makes him a complex and unsettling presence rather than a one-dimensional villain.

Yoshitsugu's role in the story is that of strategist and enforcer for the Western side. He gathers intelligence, manages alliances, and coordinates military movements. He informs his allies of Ieyasu's maneuvers, such as the abduction of Oichi and the recruitment of various warlords into the Tokugawa camp, and he takes part in diplomatic efforts to secure other lords for the Western Army, including a visit to Hideaki Kobayakawa. He also works closely with Motonari Mori, who shares his secretive and calculating approach to politics. Even when outsiders attempt to negotiate with the Western Army, Yoshitsugu remains fixed on supporting Mitsunari's war, and his quiet menace makes clear that the Western cause will not be easily turned aside.

His most important relationship is with Mitsunari. The two are bound by friendship and mutual trust, and Yoshitsugu is the ally whose judgment Mitsunari trusts enough to follow. Where Mitsunari is impulsive and emotional, Yoshitsugu provides patience and tactical thinking, compensating for his friend's weaknesses while sharing his enmity toward Ieyasu. With Motonari Mori, he forms a pragmatic alliance based on shared interests, exemplified by their cooperation in investigating the kidnapping of Matsu. Against Ieyasu and the Eastern forces, he is an implacable enemy, driven both by his devotion to Mitsunari and by his own desire to spread suffering.

Over the course of the story, Yoshitsugu's development is tied to his declining health and his determination to remain at Mitsunari's side even as the war grows more desperate. His illness is central to who he is: it explains his bitterness, his wish for revenge against a world that rejected him, and his unreadable detachment. Yet it never diminishes his resolve, and his loyalty to his friend remains the constant that guides his choices.

In combat, Yoshitsugu fights from his floating palanquin, wielding a long strand of oversized prayer beads that he hurls at enemies with wide, sweeping strikes. His fighting style suits his role as a commander, allowing him to direct battle while engaging opponents directly, and his eerie, unstoppable presence makes him a formidable opponent on the field.
