According to the lore of the light novels written by tappei nagatsuki and illustrated by Shinichirou Otsuka, Re:Zero kara Hajimeru Isekai Seikatsuthe birthday of the characters is celebrated on February 2 ram and rem, the two twin sisters who work as servants for Roswaal Manor. For those who have already forgotten them (something that is understandable, since the anime has been inactive for two years), their descriptions write:
- RAM: Ram is one of the twin maids who work for Roswaal L Mathers. She is apparently self-centered and does things at her own pace, however, she actually keeps a distance from people to make sure of them. She believes that Roswaal is the greatest and that no one else is as valuable except her sister Rem hers.
- Rem: Rem is one of the twin maids who work for Roswaal L Mathers. She often speaks in a superficially polite manner and sometimes acts without thinking. She feels both respect and guilt towards her sister for an incident in the past; therefore, she Rem tends to consider herself inferior.
Fans celebrated the occasion with a variety of illustrations, highlighting:





























Synopsis for Re:Zero kara Hajimeru Isekai Seikatsu
Leaving the shop, Subaru Natsuki finds himself in a bustling city inhabited by humans and demihumans. The city, which uses dragons and carriages for transportation, is obviously not the modern Japan he knows. However, as someone who spends his days engrossed in comics and games, Subaru assumes that he is a protagonist in this new fantasy world, drawing on ultimate magical powers. Unfortunately for him, this is not the case and things quickly go wrong when he runs into a group of thugs. Fortunately, a silver-haired beauty named Satella comes to his rescue, while she searches for his stolen insignia.
In exchange for his kindness, Subaru offers to help him on the search, which eventually leads them to a loot shop. Assuming that the badge was exchanged for money, Subaru enters the store hoping to negotiate with the owner about the stolen item. However, to his surprise, what awaits them is not the badge, but a brutal assassin who leads them both to their deaths. But instead of waking up in the afterlife, Subaru is surprised to find himself alone in the middle of the day, as if he never left town in the first place. Thus, his life in another world mysteriously begins for the second time.
