Seasons & Episode
Sento and Hakone's childhood friend, Iono, has a crush on Sento, but can't find the right moment to confess.
Sento, his boss, Hakone and Iono go to the beach, whilst Plug and Alesta, also on their day off, decide to go too. Whilst enjoying the sun, Plug notices a writer on a slump behaving strangely, despite being ranked E.
A kid named Kenta has become so depressed, that the counter-current from those that try to charge him causes a severe electric shock. He is given a Z rank and is deemed out of bounds for charging, but Plug can't help but feel like she should do something.
Plug gets scolded for trying to get back to work before her arms had fully healed, but her chief allows her to lock onto targets whilst Alesta charges them.
Plug and Alesta get called to Chief Pulse's office where they are introduced to the Rouden-chan (leakage girls), Reka Galvini and Kuran Shunt, who monitor electrical leakage, and are accused of smuggling electricity. The Rouden-chan also reveal they are aware of Sento and accompany Plug and Alesta on their next run.
As everyone gets ready for Christmas, the Juuden-chan have their work cut out for them. Reka and Kuran visit Sento and warn him about Houden-chan (discharger girls), who steal people's positive energy.
Hakone notices something weird about Sento. Meanwhile, Rona, who is annoyed that there aren't any other people who can see her, goes on a depression spree, alerting the Juuden-chan. The whole department is sent to help the affected, but they find they have to charge each target ten times to get them to drop.
Plug is a "Charger Girl" from a parallel dimension. Her job is to find depressed humans in our dimension and charge them up to revitalize their energy.
