Aya Mikoto

Sayoko, a high school girl who died young after a long battle with illness, is reincarnated as Liliana Halbard, the villainess of a crappy game world where one wrong choice leads to immediate death or the destruction of the world. By the time she regains her past life memories, her selfishness has already made her hated, and a bad ending is inevitable if things continue as they are. Sick of her miserable life from her previous incarnation, she's determined to fight against the absurdity of this crappy game world and seize happiness this time.
