High School DxD

The High School DxD watch order covers four seasons alongside six OVAs and specials, all placed in the correct sequence. Begin with Episodes 1-12, then the High School DxD Specials and the first OVA follow. Season two's Episodes 1-12 comes next, with the New: Oppai, Tsutsumimasu! OVA sitting just after it. Season three's Episodes 1-12 leads into three Born extras — the Mousou Bakuyou original video, the Yomigaeranai Fushichou OVA, and the Hero Taiikukan-ura no Holy Special — which bridge into the final season, High School DxD Hero. Watching the OVAs and specials in these spots keeps Issei's story in order and picks up the side chapters right where each season leaves off. If you've wondered where an OVA belongs or where to start, this order settles it, folding every extra into its proper place between the main seasons.
