I know that there’s a manga and also a novel, that’s what the anime is based on. I even own some of the manga volumes. And yeah I like reading manga but no, I do not enjoy reading manga more than watching anime. That’s why I said that I definitely need the anime sequel. And apart from that, I don’t think that the manga is finished either since that’s the main reason why the anime doesn’t get a new season, afaik. Of course, I will read the manga and maybe even the novel someday. But I do always wait with reading a manga of a good anime because I do not want to get spoilered. For me, it’s much more exciting to see new scenes in anime than reading them in manga. I’m just that type.
