The episode begins with Ichika in a dream similar to the one he had in the last episode of the first season. However, this time when he looks to the woman in the IS who he thinks is his sister, she grabs him and strangles him while saying 'I'll kill you'. Ichika then wakes up and finds Laura sleeping with him once again, but this time she has 'clothes' on. Laura asks Ichika to the new amusement park to end their last summer day. Ichika then suggests that they bring the whole group, angering Laura. Ichika then goes around the whole day inviting the other girls to the Amusement park. Meanwhile, Charlotte and Laura decide to go shopping. During their trip, Charlotte and Laura become mini celebrities in a clothing shop, employees at a maid cafe, and heroines when they break up a hostage situation at the maid cafe. The scene then cuts to a mysterious woman named M breaking into a heavily guarded facility to retrieve a confined IS using an extremely powerful IS of her own named Silent Zephyrus. The scene then cuts back to Ichika and the girls at the Amusement park having a fun time. The episode ends with a quick appearance by Tatenashi Sarashiki.
