Isshin Ashina
The legendary Sword Saint who mastered the blade, spear, and gun, awaiting his final duel.
Isshin Ashina is the legendary founder and leader of the Ashina clan, known as the "Sword Saint" for his unmatched skill with the blade. During the late Sengoku period, he seized a land rich in divine favor, including a foreign deity called the Divine Dragon. In the game's present, the now-elderly Isshin is on his deathbed, with the weakened Ashina besieged by the Interior Ministry. Despite his frailty, he opposes his adoptive grandson Genichiro's methods of using Kuro's blood to create an immortal army, instead warning Wolf through his private physician Emma. Isshin is later resurrected in his prime by Genichiro using a second Mortal Blade, forcing Wolf to face him in a final duel at Ashina Castle.

Reader's Guide
Isshin Ashina is the final boss of Sekiro: Shadows Die Twice, encountered in the burning Ashina Castle after Wolf returns from the divine realm. He appears in two forms: the elderly Isshin Ashina (who has already passed away before the fight) and the Sword Saint Isshin, resurrected by Genichiro's sacrifice using the second Mortal Blade. The Sword Saint fight is the game's ultimate challenge, requiring mastery of deflection, posture management, and prosthetic tools.
Isshin uses a katana, a spear, and a gun, combining rapid sword strikes with sweeping spear attacks and gunfire. His phases include a first phase with his katana, a second phase where he adds the spear and gun, and a third phase with lightning attacks that can be reversed. Defeating him is required for the Immortal Severance, Purification, and Return endings, but not for the Shura ending, where Wolf instead kills Emma and Isshin (the elderly version) before becoming corrupted.
