Bleach
Bleach is the best example of "style over substance" because it makes style into substance. Ichigo Kurosaki is a teenager who is always frowning and can see ghosts. His life changes completely when he accidentally absorbs Soul Reaper powers to protect his family from Hollows, which are evil spirits that eat souls. This is the beginning of an epic urban fantasy story with sword fights, poetic weapon names, and the famous "Bankai" transformations, where characters unlock the ultimate form of their sword. The Soul Society arc, in which Ichigo fights through the bureaucracy of heaven to save a friend, is famous for its choreography and drip. Let's be honest: Tite Kubo's character designs are the best. With that sharp, high-contrast style, everyone looks impossibly cool in their own way. It's really about the burden of power and the instinct to protect people, but it gets that point across while making sure everyone looks great while doing it.
