Glitch manga volume 3 features story and art by Shima Shinya.

When Hirata is snatched away, the Investigation Club friends (and Officer Shinoda) race into the forest after them, heedless of the danger that lies within. Given the forest is the center of glitch activity, the floating trees and otherworldly beasts may not be wholly surprising, but the sudden appearance of a masked figure moving with apparent purpose piques the Club's interest. Could this visitor from another world help explain the mysteries in Touka-cho? And can the Club find the stranger before they just as suddenly vanish once more?
