This first episode left me with a glimpse of mystery. The characters also seem interesting. Momoe seems like a thoughful person and is an airhead. Teiichi seems like a normal high school student. Kirie looks like the popular female athlete with an air of coolness. And Yuuko (who seems to be infatuated with Teiichi) seems like a goofball but with probably some harsh past experiences. A final important detail in the relation between these four characters is that Teiichi and Kirie are able to see Yuuko, who, by the way, happens to be the president of the club.
I am very impressed by the georgeous animation, atmospheric feel and direction of the series. The story and plot appear full of potential. I feel good about this series. If I had to give a grade to episode one, I would give it a 9 out 10.
