Lonely college student Sorawo Kamikoshi discovers a door to a parallel world, a strange post-apocalyptic Otherside, and makes a friend.

Sorao and Toriko meet with an Otherside expert before returning, and come across a man looking for his wife. Toriko finds a link with him because she, too, is seeking someone dear to her.

Sorao can't resist joining Toriko on the Otherside again and they set off to find a house Satsuki remembers visiting.

Sorawo and Toriko hit a difficult patch, and Sorawo teams up with Kozakura. Kozakura explains why Toriko is the way she is, and Sorawo reveals new details about her past.

An evening at Sorawo and Toriko's favourite café takes a weird turn. They have yet another unexpected encounter in the Otherside.

Sorawo and Toriko meet Lieutenant Drake's superior and learn more about what the soldiers have experienced on the Otherside; Kozakura continues to receive creepy calls.
