Unnamed Memory

Medieval stories about an awkward relationship between a regular human male and a female with supernatural/magic powers. They might not share much else, but the similarity in the relationship between the two main characters is palpable. 

Male and female lead from both anime have the exact same relationship and dynamic, except Grancrest Senki ends with closure. I suggest to not watch the last episode of Unnamed Memory until S2 comes out. 

Two medieval magic fantasy anime in which the female protagonist is voiced by the same VA. While plot-wise they're different, the settings are similar, the female MCs share a considerable resemblance in terms of personality, and the action scenes are alike.
