第 15 集: 文學社海灘之旅與山間捕蟲冒險
2015年7月11日 播出
With the arrival of summer break, the Literature Club, along with Kyon's little sister, go on a trip to the beach, staying at Tsuruya's beach house. The next day, the group head for the mountains for some bug-hunting before participating in a test of courage. Rather than the ghosts one would expect, the pairs actually end up coming across a group of beautiful fireflies. (Source: Wikipedia)
