A Witch Who Can Use Magic, but Would Rather Live Off Others

Told from the heroine's perspective. Apocalypse. Alternate world. Not a power fantasy.

A fallen star heralds the emergence of a mysterious path of calamity from the shadows. He Rumeng awakens in an unknown place, and the loss of her memories leaves her moving forward slowly. Though she bears a powerful Heart of Calamity, others covet it. With her elder sister's help, she learns the truth amid the chaos.

The natural disasters did not destroy everything. Instead, they seemed to bring even more ancient organizations back into view. The light of the Holy Church offers protection, the Magicians' Association wields fantastical magic formations, and the Ghost Clan guards its secrets... Together, and with many others, they drive the age forward.
