It takes magic to power her up, mainly Eva's own magic. Since Chachamaru is her partner, it means Chachamaru pactio is her very own life.

And speaking about magic, the specific amount of magic can give her orgasms. Since she is magically powered, will it be possible for her to transfer enough magic from her own hands and put it into that key to give THAT feeling?
