Kotaro's diary synopsis
They ended up naming their group "Franchouchou" without my permission. The role of group leader was thrusted onto Saki's shoulders. It seemed like a good idea that I deliberately made myself known as the producer. Speaking of which, it's not a bad idea that they ended up operating more independently. Now these lazy, chatterbox zombie idols are getting into it a bit, they can start earning their keep. We'll go to the hot springs to hit a business deal. Hopefully, the secret that these girls are just zombies with makeup won't leak out, or everything's done.
