((Would he be Suzaku because he’s like a bird and can’t be caught? Why would he be like Byakko?))

(Well, that and Suzaku also tends to be represented by a phoenix, due to it’s association with fire. I’d say Kid certainly rose from the ashes…

As for why Byakko, well, the colour white, first and foremost. I like the association with metal more than fire, for someone like Kaito, and I also like the season of fall for him over summer. Byakko also more closely represents justice, or at least, fighting to protect, while I picture Suzaku as more the impartial and knowledge seeking type. Neither fit perfectly, but arguments could be made for both. Honestly, I was going with Suzaku between that and Genbu, but I personally think he does fall in a line somewhere between Suzaku and Byakko. Of course, if you were matching up people like the Gosho Boys or such, Kaito would probably be pushed back to Suzaku while Heiji get’s Byakko, and he’d suit it better, but Kaito is far from strictly Suzaku. (And then I put Shinichi as Genbu and Hakuba as Seiryu.))
