Episode Glossary
"Protocol of the Two-sided Gospel: X-Day Protocol" (双対福音のプロトコル, Sōtsui Fukuin no Purotokoru) is the third episode of the anime adaptation of the Steins;Gate 0 visual novel.


As Mayuri Shiina prepares for a Christmas party for everyone at the lab, Rintaro shows Amadeus Kurisu – who he keeps a secret from his friends – around Akihabara and the lab. On Christmas Eve, Leskinen and Maho end up joining Rintaro to the party, which proves to be more than a surprise when Suzuha assumes it is an ambush and almost attacks Yuki. While everyone else enjoys the party, Mayuri overhears Rintaro speaking happily with Amadeus Kurisu, prompting Maho to step in and remind him that the real Kurisu is still dead, inadvertently sending him into a shock.
