She is just an ordinary girl, and her biggest wish has always been to work hard to survive. She thought that her happy days would begin once she was admitted to a school that offered a scholarship. However, after encountering a clock belonging to the most terrifying witch, all her daily life was overturned. The familiars that the witch had made a contract with came one after another, including Weiss, the noble prince of the vampire clan, Wyatt, the destructive werewolf who wandered and lived alone, Mason, the gentle and kind mermaid who was always sleeping, and Hill, the siren who charmed all living beings and feared that the world would not be in chaos. The arrival of the familiars has made her peaceful days gone forever. Faced with sudden challenges, the conspiracies of the major races are gradually revealed. Can she escape from this terrible predicament? Or do you mean to sink forever?
