11eyes - S01

Seven years ago, Kakeru Satsuki lost the last of his family when he watched his sister commit suicide, and he ended up in an orphanage. Now in high school, things seem to be going well for Kakeru. Until one day, while out with his best friend Yuka Minase, the sky suddenly turns red and everyone except the two of them vanishes. As monsters begin chasing them, death seems certain, but the world inexplicably returns to normal just in time. The very next day, the same nightmare, called the Red Night, happens again, but Kakeru and Yuka are saved by their senior, Misuzu Kusakabe. The three soon learn that a girl trapped in a crystal appears to be behind it all. What's more, other students from their school are involved, each dealing with their own troubles. To protect Yuka, Kakeru has to grow stronger and join forces with his peers to put an end to the Red Night for good.
