A strange and cruel world that takes away your memory, but gives out power in return... the ability to get it. A person who woke up in an unfamiliar city, received the System as a gift, but wants to return what was taken from him. Striving, but very soon realizing that it is extremely difficult to do this in a changed world full of monsters. Monsters, recently or long ago, but formerly people who have been exposed to a powerful virus. Some he deprives the mind and transforms into monsters. Others, who turned out to be resistant to infection, are endowed with new, unique opportunities. So it remains for a person deprived of a considerable part of his own "I," who received the nickname Bes from the world itself, to go forward, leaving behind corpses and death, pain and regrets about what happened.
