The power source of Carol and the Auto-Scorer’s alchemy. Their personal experiences that are stored in the brain as memories can be used and turned into combat potential. However, in order to obtain enough memories to make this system efficient they have been forcibly stealing and collecting memories from other people’s minds. Garie, who possess the holy grail, is the most skilled at handling memories and in addition to collecting them, is also capable of sharing them among the other Auto-Scorers. Leiur and Phara are not capable of sharing any memories, however they can forcibly collect them from humans. Micha, the doll specifically designed for combat, can not gather memories on her own and as long as she does not receive any from Garie, has no other means of collecting enough to make herself functional.
