From Hoshikuzuu Scans:

Listen to this. While we were at a Yakitori place talking about otaku stuff, we were blown into an alternate world. You may not believe what we are saying, but what is more unbelievable is that there are no girls in this world!! None! Nada! Zilch!!! Auuuugggghhhh! A bunch of good-looking dudes who like yuri: Kagome, Fuuga, Kamakura, Sakuragaoka, Ototachibana, Musashino, Hanadera. How are they going to live in a world full of only dudes!? It’s full-on survival of the fittest! Not! So it’s just your average unusual manga! Rest assured!
