Stigmatized Scythe of The Heavens

One who committed unforgivable sin shall not be invited to heavens above. They'll instead be servants of the gods. Not remembering her past life nor the sins she committed, Kage ascended as a "Nightmare Queller".

Rumours has it that if the sinner catches the attention of the heavens, they might have a chance to redeem themselves and will be given a choice; eternal rest or reincarnation.
