S Since I'm Not Popular, I'll Become an Enigma

The original video animation episode opens with a fourth wall breaking sequence in which Tomoko is commanding Yū and Kī how to act in order to raise the ratings of the anime to which Kī responds that the "good times" are over.

After the title sequence, a story about a "mysterious girl" (Tomoko) and her meetings with Aomatsu (Tomoki's friend) in middle school's roof is told from two perspectives. First from the perspective of Aomatsu, then Tomoko.
