Aijaku Shōji

is an ability granted to the wielder who possesses Sairin. It allows the wielder to be given a second chance to life, but in all honesty that is a mere phrase. Because even if the wielder wishes to remain in the living world, even if they walk around with a brutal wound, as long as he or she does the fatal blow to themselves or through the use of their spirits (whom can be considered to be a part of them), they will be revived.

To what extend the reanimating technique goes is unanswered. But it seems that after being revived the wielder will no longer suffer of the wound, which is usually all healed up. Instead the wielder will suffer of an intense agonizing pain that could torment the Sairin wielder for days to weeks. And it is presumed that the time between dead and to be revived ranges from four hours to two-three days.
