Plug Cryostat is a Juuden-chan from a parallel world know as Life Core. She works for a corporation named Neogem, ans she has a very peculliar job. Whenever she sees someone depressed, Plug charges them up in order to boost their self-esteem. All she does is prevent them to commit a suicide attempt.
Using some invisible suits, Plug flies around finding people that need to charge up. When she finds someone, she pulls out a giant electrical plug and uses it to charge the person. One time, she fails to ground herself to avoid an electric shock, in the end, she burns her own suit, something that will cost her to work overtime.
One day, when Plug was working, she meets Sento Oumi at Sunday Mama, a family restaurant. Somehow, Sento is able to see Plug, of course that he is surprised, and more than that, he freaks out thinking that it is a burglar and hits Plug with a baseball bat.
Meantime, Sento’s sister, Hakone Oumi and her best friend Iono Tomonaga, who can’t see Plug, ask him what is he doing waving the bat in the air.
Plug realizes that Hakone is feeling down and tries to charge her up, but Sento prevents Plug to do any weird thing to her little sister. Later that night, Plug tells Sento what she is and what is the purpose of her job.
After that, she tries to find out why Hakone is feeling depressed. Finally, she finds out that the reason is her older brother Sento. Plug tries to convince Sento to cheer his little sister, but she only finds out that Hakone went out, and that she will try to suicide. When Sento tries to save his sister, Plug finally has a clear chance to charge Hakone and saves her.
Plug Cryostat is a Juuden-chan, someone from a world that is parallel to our own, capable of recharging people who are depressed or unlucky. She is however not very good at it and is a bit of an airhead. Because she has the ability to use phasing, she normally can’t be seen by regular humans. This is done so she can do her job without causing distraction. She loves to watch a rather ecchi anime series called “Millie-chan”. Whilst other Juden-chan focus on charging people and getting paid, Plug focuses on discovering the root of their problems so that they won’t become depressed again.
Alesta Blanket is Plug’s fellow Juuden-chan and rival, who becomes her supervisor. She is rather serious when it comes to work and is rather annoyed with how Plug is carrying out her job. In turn, Plug finds Alesta irritating for interfering with her work and the two girls tend to fight a lot. She sometimes ends up crying, which Plug uses as blackmail material. She has feelings for Sento from the very moment she saw him, but he is rather oblivious to this. Following their first meeting, Alesta seems to have garnered a fetish for being hit by a baseball bat.
Sento Oumi is a young man who is the only human capable of seeing both Plug and Alesta. He works at a family restaurant and has a rather short temper, which results in frequently hitting Plug with a baseball bat or whatever is within reach; this has become a running gag in the series.
Hakone Oumi is Sento’s younger sister. She lives together with her brother and wants to do household chores, but Sento told her not to because he feels responsible for her. She cares for her brother and is frustrated that she is not allowed to help him, making her depressed and unhappy, and a prime target for Plug.
Iono Tomonaga is the best friend of Hakone. She has a crush on Sento and is struggling to confess to him, but Sento seems to be unaware of it and only thinks of her as a little sister, much to her frustration. More at: Wiki
