Immortal Severance

Lore & Background

The Immortal Severance ending requires Wolf to collect the necessary materials for the ritual, including a weapon that can kill immortals known as the Mortal Blade from the Divine Child – the sole survivor of experiments with the Rejuvenating Waters. After collecting most of the ritual elements, Wolf is confronted by Owl, who faked his death in pursuit of the Dragon's Heritage and revealed to be the one who stabbed him three years ago. If Wolf refuses Owl's orders, he kills Owl in combat and enters the divine realm to recover the final ingredient for the ritual from the Divine Dragon itself.

Upon returning to the mortal realm, Wolf discovers that Isshin has passed and Ashina is under attack by the Interior Ministry's troops who have set fire to the castle with rockets and flamethrowers. Fighting through the burning castle, Wolf eventually finds Kuro under attack by Genichiro, who has retrieved another Mortal Blade. Upon defeat, Genichiro sacrifices himself using the second Mortal Blade to revive Isshin in his prime so he might restore Ashina, a wish that his grandfather attempts to honor despite disagreeing with it.
