Whilst looking for some targets to charge, a charger girl named Plug encounters Sento, who can actually see her and hit her. Plug notices his sister, Hakone, is showing a lot of depression, but Sento refuses to let her stick a giant plug in his little sister's back.
Whilst trying to charge up some targets, Plug finds herself beaten to the punch by her colleague, Alesta. They then start to notice a lot of repeaters, people who have already been charged but have become depressed again. Plug goes to Sento for some advice, who says the simply charging them won't fix the cause of their problems.
