The Many (Manga) Portrayals of Cesare Borgia (2011)

Off topic:

I learned about The Borgias while reading Mario Puzzo’s The Family. He spent like 20 years doing historical research about the family and their business and compiled a very entertaining book if you’re a history nerd which also likes a good narrative (even if that means concealing a little bit the historical strictness).

Mario Puzzo (yes, The Godfather’s author) died before publishing the novel and his girlfriend published it instead; the last few chapters are clearly hurried and that’s why you’d read bad reviews online. But I really enojoyed it.
