@StanzBlood In fact, it's even better to read the manga, after all, the Anime puts much more Ecchi and unnecessary scenes than the manga itself. Not to mention the moments of rage that the Protagonist goes through, as well as the development of Issei throughout the work, which, unlike the anime, is extremely easy to perceive.
So simplifying: reading the manga instead of watching the Anime could even give an experience much better than intended.
