Otherside Picnic 03 (Manga)

In this sci-fi/fantasy survival thriller, the dangerous and deadly realm of the Otherside--where urban legends roam--calls to two women, both in search of something. As they set out to sate their curiosity and explore this other world, will the most earth-shattering thing they discover on the Otherside be their feelings for each other?

The hunt for Satsuki continues, but Sorawo begins to have second thoughts in the face of Toriko's heedless urgency, leading to a heated argument...
 
And when Sorawo loses her way in the space between reality and the Otherside, only to run into another mysterious entity—the Time-space Man—she discovers that Toriko's crossed to the Otherside without her!
 
Unable to locate Toriko, Sorawo must put her feelings about Satsuki aside and enlist Kozakura in the search for her missing friend...
