Rockin Robin serves as mentor to Vanilla and Chocolat, documenting their progress as they work to steal hearts. He's a well-known rock star in the Human World, though his tough exterior can throw people off—despite seeming rude or standoffish, he genuinely cares about those around him, he just doesn't show it much.
There's more to him than meets the eye. According to Blanca, Robin is actually 6800 years old and relies on facial masks to keep his youthful look. He has a notable fear of sharp objects, which is kind of surprising given his otherwise cool demeanor.
