This is going to be a very strange request. Yes, I am asking for recommendations to an anime. As for what I'm looking for, I would say I am looking for immaculate world-building. Kekkai Sensen truly has built a world, unlike basically any other story I've seen. Would really appreciate something with a New York kinda vibe. Also, would prefer some comedy as well.
Why do you try the authors other work Trigun? I would also suggest World Trigger. As for novels, if you’re okay with BL I would suggest The Earth is Online. It’s a slow start but I’m solid about its world building. In general as a adoring fan of Kekkai Sensen. I would look out for infinite flow, or nightmare game series. Sadly I can say much more titles without all of them being BL. But a big title would be Tower of God.
