Zetsuen no Tempest

Both anime have 2 or more events taking place in different time periods, where the future time period is apocalyptic. These events are somehow connected, revealing everything dramatically at the end. Zetsuen no Tempest is a bit more deep, heavily relying on quotes from The Tempest by Shakespeare while Sekimatsu Occult Gakuin is still worth a watch with its own original storyline.
