Samira is a Valkyrie who lived among people in our world. One day she got into a taxi and... found herself in a hospital at the crossroads of seven worlds, almost completely losing her memory of the past. Here Samira, a former advertiser, learns the basics of magical and conventional medicine, saves lives every day, studies at the Academy of Magical Medicine and... witnesses a war with creatures from the lower worlds. And also... and she also has an admirer - a man who is not used to rejection and considers Samira almost his own.
