Haruka and her club mates went on a summer vacation trip to her grandfather's house. In the first half of the episode we saw the protagonists traveling on train to their destination. After arriving, Haruka's grandfather dropped them at a creepy, abandoned hospital, which was part of an attractions park prepared for them. In the second half of the episode the protagonists had fun at the beach and lighted fireworks at night.
Episode 6 of Kotoura-san was so-so. The members of the ESP Research Club did the typical things beach episodes in anime have the protagonists do. The episode was entertaining, especially seeing Haruka mad because she is not as well endowed as Yuriko and Hiyori. However, the episode was very uneventful. The only saving grace was when Haruka's mother arrived to the beach at the end of the episode. I give this episode a 7 out of 10.
Halfway through the series, Kotoura-san struggles to find an identity. The first thee episodes hinted that this series was going to be kind of dramatic. But the last three episodes have had a lot of silliness. I do not mind some comedy, but this series has potential to have substance. I hope Kotoura-san improves. The grade for the first half of this series is 7 out of 10.
