Drifting Net Cafe is a science fiction mystery involving a group of patrons trapped in an internet café, which has become a strange universe of its own.

The story focuses primarily on the relationship between Koichi Toki, a salaryman who leads a trouble-free but unexciting life, and Kaho Tono, his first love whom he never forgot.

The manga was adapted into a TBS television series on April 15, 2009, and stars Atsushi Itō as Koichi Toki.

The group suffers from disagreements, several escalations of anger and despair trying to survive while Toki and his friend's relationship progresses little by little.
