Steins;Gate

A few months after the events of Steins;Gate, Rintarou Okabe and his group of friends are invited to tag along with their acquaintance Faris NyanNyan, who is participating in a Rai-Net battle event in the United States. There, they meet up with an old colleague: Kurisu Makise, who has been recalling fragmented memories of events that happened in the other world lines in the form of dreams. She confronts Okabe, questioning him as to whether these events—particularly the incidents between the two of them—did indeed happen.

Mayuri and Kurisu attempt to make some fried chicken with help of a cognitive computing-based Upa terminal, only to find they lack the actual ingredients they need. Thus, with Upa's help, they find something they can make with what they have in the lab.

After Rintaro and Kurisu get into an argument with each other, they both use Upa to try and navigate their way home without bumping into each other. Instead, Upa arranges them to take the long route so they can make up with each other.

When it becomes apparent that Rintaro and Daru pretty much wear the same clothes all the time, Kurisu uses Upa to try and come up with some different outfits for them based on their hobbies and personalities.

Following complaints from Yugo, Upa heads up a meeting concerning a potential new location for the lab, much to Rintaro's dismay.
