Otherside Picnic 16 (Manga‪)‬

The dangerous and deadly realm of the Otherside—where urban legends roam—calls to two women!

Trapped alone in the interstitial space between the real world and the Otherside, Sorawo must crack the riddle of how her unexpected reflection in mirrors is linked to her and Toriko’s past. But Toriko, connected to Sorawo only by phone call, doesn't realize that Sorawo is being stalked by the worst version of herself in that parallel dimension... 

Meanwhile, awaiting the pair in the Otherside is a mysterious elderly woman in a dog-filled mansion, their old acquaintance Mr. Abarato, and—once again—the Eight-Foot-Tall Lady!
