Sega streamed the opening of the mobile game Re:Zero Kara Hajimeru Isekai Seikatsu – Lost in Memories , a game based on the Re:Zero .
The game is scheduled for release this summer and will be free-to-play, but with microtransactions.
Studio WHITE FOX produced the opening animation. Kenichi Kawamura , who worked as a storyboard artist on the first season of the anime, is storyboarding and directing the animation. The original light novel , Tappei Nagatsuki, is supervising the project.

Players will play as Subaru in the game and follow the events of the anime. However, players can also make a different choice "at that moment," leading to a different "what if" story. Additionally, the game will also feature a new original story.
The first season of the anime has 25 episodes, was based on the light novel, and premiered in April 2016. Crunchyroll streamed the series as it aired in Japan. Crunchyroll is also streaming the anime spinoff series Re:Zero ~Starting Break From Zero~ and Re:PETIT ~Starting Life in Another World~.
Re:Zero – Director's Cut, an updated version of the first season of the anime, premiered on January 1st. The new edition of the 25-episode first season adds new scenes and restructures the episodes to be one hour long.
