"Crap... I think I'm hooked." The cute introvert is the only one who can make me feel good. Tsubaki is the textbook definition of an introverted wallflower, but her extroverted classmate Sara is her biggest fan. Sara adores the curly-haired Tsubaki so much, but struggles to become friends with her. That is, until one day when Tsubaki suddenly starts heaving in the changing room when it's just the two of them. "I'm hypersexual..." she feverously explains. She was avoiding Sara because she had feelings for her. Seeing Sara's confusion, Tsubaki thinks it's over for her until Sara responds in a completely unexpected way. "Tsubaki, it's all right... You can touch me if you want..."

After having chosen the life of a professional shut-in, a maid named Villhaze suddenly appears and informs Komari that she has been chosen as the newest General of the Moolnight Empire's Seventh Battalion (comprising solely of mutinous ruffians)!
