Dandadan Vol. 1 — Manga Raw / Buy Official

Momo Ayase, a high-schooler who believes in ghosts, and Ken "Okarun" Takakura, an occult nerd obsessed with aliens, each dismiss what the other believes—so they split up to prove it, one heading to an abandoned hospital, the other to a haunted tunnel. Momo is ambushed by aliens while Okarun is caught by the yokai Turbo Granny, and both discover the other was right all along. Momo's hidden psychic power awakens, and together with Okarun—now missing a certain body part—they plunge into a chaotic war of aliens and spirits. Youth and battle break loose at once in Volume 1.
