• boss type: Main Boss
• note: Isshin Ashina - the final boss of the Shura ending, fought at the top of Ashina Castle after betraying Kuro (choosing to obey the Iron Code at Owl's ultimatum). The encounter opens against Emma, the Gentle Blade, then continues into Isshin: an early sword phase followed by a fire phase with flame attacks and an unbreakable grab. This is distinct from the standard final boss Sword Saint Isshin, who is fought in the Ashina Reservoir wheat field on the non-Shura (Immortal Severance / Purification / Dragon's Homecoming) endings.
