The two of them started talking after Momo rescued Okarun from getting bullied. However, an argument ensues between them since Momo “believes in ghosts but denies aliens”, and Okarun “believes in aliens but denies ghosts”. To make the mutual deniers believe in each other, Momo goes to an abandoned hospital, which is a UFO spot, and Okarun goes to a tunnel, which is a haunted place. In each place, they encounter overwhelming paranormals that transcend comprehension. Amid predicaments, Momo awakens her hidden power and Okarun gains the power of a curse to challenge the paranormals! Their fateful love begins as well!?
