Requiem of the Rose King (Manga, the anime is trash)
Loosely based on the Shakespearean plays Henry VI, Part 3 and Richard III, it's about intersex Richard III during the tumultuous Wars of the Roses period in English history. The artwork is AMAZING. Richard is a tragic and cool character and observing how each character treats him is very interesting. We get to see the evolution of how he feels about his body, and about gender itself, and how it determines so much of your life, especially in the 1400s.
