The anime is good. The manga is better (or the anime stopped too soon).

Romantic Comedy, Psychological (parody) Why it’s popular: Two elite student council geniuses love each other but refuse to confess, believing the first to admit love "loses." They wage mental warfare to force the other to confess. Recommendation: The anime (3 seasons + a movie) has a legendary narrator and creative direction. The manga is complete (28 volumes). The ending is satisfying. Best for: Laughter, mind games, and the "Chika Dance."
