The obsessive fan club premise sounds hilarious—two friends competing over who loves their crush more creates perfect comedy material. Friendship and rivalry in romance is great comedy; the balance between supporting each other and competing for the same person offers constant humor. The key visual has nice soft colors; the pastel palette gives it a gentle, school life atmosphere. Rom-coms about rivals becoming friends are fun—watching characters navigate loyalty to each other versus their romantic feelings makes for engaging storytelling.

The TV anime "Kirio Fan Club" based on Pon-chan, the Fish of Earth's original work has released its key visual and first PV, revealing the April 2026 premiere date and four additional cast members.

The Story

Kodansha USA is set to publish the first volume of Chikyu no Osakana Ponchan's original manga in Spring 2026.

For Aimi and Nami, proving their love for Kirio means conducting nightly rituals to entice him into their dreams and listing out what exactly they like about him, down to the very last organ. These friends and rivals in romance pose deep questions to each other to prove their devotion to this boy who hardly seems to know they exist. But when push comes to shove, will they choose their hilarious friendship over a shot at love?

A rip-roaring romcom about the friendship behind what is fair in love and war, recommended for fans of Nichijou and City.
