Joule(VA: Megu Sakuragawa)［My consciousness is still here with you.］Joule exists completely in the form of a spirit residing inside Gunvolt’s body. She once existed as a young adept girl, but upon her untimely death, her spirit was released from her physical body and now exists only in that form. Once a very shy girl, she has become much bolder since the events of the previous game, in some ways becoming more like her former alter ego, the virtual pop star Lumen. Her septimal power is The Muse, which enables her to fully synchronize with Gunvolt and increase his abilities through the power of her singing. In her previous form as Lumen, she had a more adult-like appearance, but after a certain incident, she lost a large amount of her power and her appearance changed into a more child-like form.
