Yes, indeed. The Re:Zero manga exists and presents the story in a graphical format. It might have some differences from the original source, but it still captures the essence and excitement of the series.
The magic system in Re Zero All Light Novels is quite elaborate. There are different types of magic, from elemental magic to more unique and rare forms. The story also delves into the politics and power struggles within the different kingdoms and groups in the world. It's not just about Subaru's personal journey, but also about the bigger picture of how this world functions and the conflicts that arise within it.
