Blue Drop - S01

Five years ago, Kamioki Island was the site of a horrific event-one so terrifying that it erased Mari Wakatake’s memories while leaving everyone else dead. Now, unwillingly enrolled at a secluded girls’ school, Mari doesn’t realize she’s being watched. Someone-or something-is waiting for her memories to resurface. Deep in her mind lies the darkest truth: though Mari was the only human to survive, she might not have been the only thing to walk away. As an unnatural presence in human disguise infiltrates Kaihou Academy, Mari’s only chance rests with a mysterious girl she feels drawn to but can’t bring herself to trust.
