Have you ever wondered about the real villainess---the one whose body the heroine steals? Where does her soul go? Is she still alive, watching helplessly as someone else lives her life? Or does she simply vanish, forgotten by the story itself? Most never ask. Most never care. But this time, the forgotten villainess doesn't disappear. Her soul awakens... inside the body of the girl who stole hers. [Host's vessel, good luck with your new life. Don't corrupt the former body of my host.] "I am #179, an Advanced Human Artificial Intelligence Assistant." "Is that really a saint power?" "You talk big for a blind girl." "Stop! You're only making it worse!" "She doesn't love me... but I love her." "Are you telling me that blind girl killed Grandpa?" "Why don't you trust me?" "Don't be fooled. Some aliens can copy your appearance." As her journey continues in a new body, in a new life, she doesn't realize how far she's gone--- until there's no way to go back.
