It seems that they forgot about Yuuko’s “shadow half” on this episode and decided to do a school festival instead.
While Yuuko will scare the hell out of people when she turned the club into a haunted house…
Okonogi dragged Kirie into a maid cafe and turned her into a cute, nekomimi, maid girl!
Wow, looks similar to Yuuko… Although she doesn’t have the “oomph!” on her chest! Still, Kirie has her doubts on Yuuko.
But anyway, I hope the next episode might pick up the plot!

This ep really leveled up my opinion of Kirie. I hope she starts playing a more active role (or starts really pushing love polygons).
