High school hottie Momo Ayase, who has just gone through a breakup, helps Ken Takakura, a strange guy in her class, and protects him from bullies. Ken thinks he’s found a friend who, like him, is obsessed with “aliens” and UFOs. But there’s a twist—Momo thinks aliens are nonsense and only ghosts (supernaturals) are real!
A rivalry begins between the two: Ken wants to prove aliens are real, and Momo wants to prove ghosts. But it doesn’t just end there, as both suddenly find themselves caught in a carnage of real urban legends and strange and eerie creatures. On this dangerous journey, both gain strange “superhuman” powers and learn to make up for each other’s weaknesses. Is it just a battle for survival, or is there something more hidden behind this unique friendship?
