 If you liked Re:Zero kara Hajimeru Isekai Seikatsu |  ...then you might like Vivy: Fluorite Eye's Song |
Paladin. Re:Zero and Vivy's Song have something in common that I believe is really effective, and that is their means to push forward some hopeless situation that one must prevail through anyway. Re:Zero does this with Subaru in a new world, taking on his volunteer mission of being the knight to his newly found damsel, though not in distress. The same is true with VIvy, although she is on a mission to save the entire world rather than a singularity. In some sense, the two do have the means to show that actually, the world they situate in is in their control bringing forward more "hero"

Same author. It is really easy to tell that these two series are made by the same person. If you like the darker themes, great characters, amazing story, and awesome action of Vivy, then you will probably like Re:Zero.

Vivy: Fluorite Eye's Song not only was animated by Attack on Titan's former studio, Wit Studio but the story was written by the author of Re:Zero, it'll send you on a thrilling, yet emotional ride. This is more than just an idol anime, look into it if you liked both Re:Zero and Attack on Titan
