Steins;Gate: Egoistic Poriomania
Highly rated by the community—a strong pick for fans of the genre. A comedy series that brings humor and levity to its premise.
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.
