In Spring 2018 half of the universe was winked out of existence with a snap; two of those victims woke up in an entirely different universe. Peter Parker and Steve Rogers are transported to the Kingdom of Lugnica and quickly become entangled in a contest for the royal throne. A bit of a "What IF..." retelling of the first season of the show Re:Zero with some twists and turns in there, plus the added bonus of watching Peter and Steve work together with new found friends against dangerous enemies.

After having dealt with the challenges of the Pleiades watchtower, Natsuki Subaru is summoned by an unknown deity to help fix some worlds from the fallen Natsuki Subarus. It is up to him and his allies to help correct these worlds.
