The mystery of amigara fault online dating
Sometimes, an existing anime series gets a manga adaptation; see Anime First for examples.
One generally reads them right to left, unless the manga was flipped during its English printing, which rarely happens these days, or the mangaka decided to write it left-to-right for some reason, which happens even more rarely but does occur from time to time, or the mangaka made two versions him/herself, which is extremely rare.
The Enigma of Amigara Fault (Amigara means "Empty Shell") is a short story originally published along with the second volume of Junji Ito's Gyo, but has nothing to do with the story.
People are being unnaturally drawn into a mountainside fault.
The work also includes a pair of bonus stories, titled "The Sad Tale of the Principal Post" and "The Enigma of Amigara Fault".
The story is about people who are strangely drawn to a mountain, and I really shouldn’t say more than that. Tadashi and Kaori manage to return to Tokyo, although Kaori becomes irritated and paranoid, claiming to smell the fish.
