1

A charger girl named Plug searches for targets to charge and encounters Sento, who can see and hit her. She observes that Sento’s sister, Hakone, is suffering from severe depression. Although Plug identifies the root cause as Hakone feeling useless because her brother prevents her from helping him, Sento dismisses her concerns. Hakone contemplates jumping from a building, but Plug and Sento work together to save her. They successfully charge Hakone, which restores her confidence and enables her to communicate her feelings to Sento, resolving the emotional conflict between the siblings.
