Who are Momo and Okarun? Two opposing beliefs start DANDADAN
One believes in ghosts, the other in aliens; their argument sets the story in motion.

Momo comes from a family of spirit mediums and believes in ghosts but denies aliens. Her classmate Okarun loves the occult and believes in aliens but not ghosts. DANDADAN’s official introduction places that difference at the beginning of the story.
They begin talking after Momo helps Okarun when he is bullied. To prove the other wrong, she visits an abandoned hospital associated with UFOs while he goes to a tunnel said to be haunted.
Their encounters challenge both of them: Momo awakens a hidden power and Okarun faces a curse. This is only the anime’s published opening premise; later developments are left to the story.
