Re:Zero Lost in Memories (Re:ゼロから始まる異世界生活 Lost in Memories) is a game developed by SEGA and is the first official mobile game in the series. It is a free-to-play game with microtransactions and was released on September 9, 2020. The game's services were terminated on May 12, 2023.

Story
The game features a story that is a retelling of the anime, however, it also divided into 3 chapters: "Main Story", "Ver. Main Story" and "IF Route". The game features branching paths that lead Subaru Natsuki to a different outcome of the story, turning into a "What IF" scenarios. In addition, it includes a new original story that was not included in the anime and the project is supervised by the series' author – Tappei Nagatsuki. It also features the original voice actors Kobayashi Yuusuke, Takahashi Rie, Minase Inori, Murakawa Rie, Uchiyama Yumi, and more, reprising their roles from the Re:Zero anime. Aside from the anime's voice actors, Studio White Fox is also providing SEGA with some animations, such as the ones used for the opening sequence.

Summary
It begins when the main character, Natsuki Subaru, who suddenly lost his memories while he wanders around in the forest at night. The mysterious girl named Shion suddenly rescued Subaru from being attacked by someone. With the help of Shion, who calls herself an illusionist, Subaru takes action to regain his lost memories.

In order to regain Subaru's memories, the player will first challenge the “Recollection Town Quest”. In the remembrance town, he will relive the scene where Subaru's memories is reproduced with Shion, but there is also a scene where the characters he knows are attacked by the enemy's technique called "tampering".

Why is Shion acting together with Subaru? Who is the criminal who took away Subaru's memories in the first place? A big story flow is prepared just from this point, so the purpose is clear as a player. Let's enjoy the adventures of Subaru.
