High School DxD: Not added because too many episodes releases on same day, but the it's a release on 2012 (Based on MyAnimeList)
Maybe we can add a wrapper for Anilist and MAL to check if we have the same size on episodes, and if it's true, we can check the correct release date on MyAnimeList

Same thing with Goblin Slayer (https://gw.api.animationdigitalnetwork.fr/video/calendar?date=2021-03-24)
