Anime fans often love a given series' main character the most, since such characters are written to be more compelling and memorable than anyone else, like Son Goku and Tohru Honda. Still, the main character's family members or best friends might be a series' best character instead, at least according to some fans. Supporting characters sometimes feel like the true star of the show.
