Gekkan Shoujo Nozaki-kun, Binan Koukou Chikyuu Bouei-bu LOVE! Recommendations
Although Nozaki-kun focuses on a manga artist and Binan is about magical boys, both series are full of wacky, often sarcastic humour that doesn't take itself too seriously. They both take the tropes common to the genres they parody (shoujo manga in Nozaki's case and mahou shoujo series in Binan's) and turn them upside down to create fun comedies.
Same kind of humor, making fun of genre stereotypes. Expect lots of laughs with these animes, so if you enjoy a good comedy you sure gonna like both
They are not about the plot, but about the character-driven jokes, and making fun of genre stereotypes.
