Roronoa Zoro: 5 themes
Not a day goes by that Zoro does not remind himself of his goal. Who, what and why he trains for.
He bears her sword and her dream with these two hands and Zoro will die before he sees either shatter. He chants her name to himself when he's weak or breaking. It's a mantra that reminds him not of the girl, but what she might have been. What he could be in her place.
And somewhere, a black suspicion lingers – that somehow, if he had not in the brashness of youth stormed into the dojo that day, Kuina might still be alive. This conviction grows daily until he's certain that only when he's the strongest swordsman in the world can he absolve himself.
Luffy is his Captain. He'd follow him anywhere – land, sea, sky.
Luffy is the Pirate King, present and future. This is as clear to Zoro as the ocean is blue and sake is good. He's only waiting for the rest of the world to realize it, and it's with a grin that he thinks to himself: It won't be long now.
Rivalry (aka Kinship)
Maybe it's Sanji's eyebrow (retarded) or his suits (pansy) or his flirting (moronic), but Zoro could feel himself bristling every time their eyes meet.
Or perhaps it's that they're both young men with arrogance to spare and far too evenly matched in strength.
In battle, he'd trust Sanji with his life and vice versa. Battle over, they try to kill each other. Zoro wouldn't have it any other way.
Zoro is absolutely certain that if he doesn't die fighting Mihawk or on one of their hare-brained adventures, Nami would finish him off. His ears ring from her henpecking. His head throbs from her fist. He can't hit her and he can't intimidate her. His latest strategy is to pretend sleep until she leaves him alone.
Roronoa Zoro – legendary ex-bounty hunter and 120,000,000 beri pirate – can only inwardly shudder at the depths to which he's sunk.
