There's a new girl at Superhero School! Her name is Supergirl and she is the most powerful girl in the Galaxy. Once upon a time her name was Kara, she lived with her mother and father on the planet Krypton. However, Kara's parents died along with their home planet, and the girl herself managed to hide on Earth. Kara is incredibly strong, has super hearing and x-ray vision, and she can also fly! Of course, she belongs at the School of Superheroes - there a new name, new friends and new opportunities await her. True, Supergirl herself is not sure that she fits the high standards of the School. She is so clumsy, she always cannot calculate her remarkable strength, she breaks something, drops and collapses... Friends are, of course, great, but there are also enemies who are only happy about her mistakes. Maybe I should have gone to study somewhere else? Supergirl does not yet realize that her abilities will soon be very useful to the School of Superheroes. After all, something extremely strange and even suspicious has been happening here lately...
