Komatsu Naotaka, Shoryu. He is my favorite. I just love the fact he is a taika from when Hourai didn't suck, and his personality. And his jokes. ^^
My second is Shokou. He's so evil, it makes me laugh. When Asano shot that brat in Enho's house, I was thinking of Shokou laughing, and I laughed, too. In an evil way.

I love evil. And remember, kids: He was just proving the heavens are not perfect.
My third is Shokei. I loved her from the very beggining. I felt so sorry for her, I even cried. "SHE DID NOTHING!", I thought. When they were going to kill her at Rinki, I wanted to swoop down, kill all of them, and then rescue her and take her home. <; She did nothing to deserve all of that. I was worried for her safety the entire time. But then she started to mature, and I loved her even more. <3 She has the best singing voice ever made! I want to marry her now.
I like mostly all characters, but I like
Tsuki no Kage, Kage no Umi substantially less, so I don't like Rakushun, Kou and Kourin much. <_< Still like Sugimoto before she returns to Hourai, though. And I still love Keiki very much, thank you! He was my favorite until Shoryu appeared. ;D As well as Taiki, Gyoso, Rokuta, Sekishi, Youka(from Mt. Hou), Chuutatsu, Gekkei, Enho, Kantai, Koukan, Seikyo, Gahou, Koshu, Seki...too many awesome characters.
I thought Asano was a great character: When everything is complete(both the novels and the anime), I'll have the anime over the novels because of Asano and how crazy he was. I just wanted to give him a hug. << And I wanted Asano x Suzu. ;-; Speaking of Suzu, I didn't like her much...until she met Asano. And when she spoke to Shokei in wild hair! D: SHE SHOULD ALWAYS USE WILD HAIR!
Aaaand no one in this topic mentioned Atsuya. I thought he was a very interesting character. The "other Shoryuu". He would impulsively do anything for his people...even rebelling against the heavens. But...was he saving those children for his pride, or was he the savior of all people? At any case, he was Shoryu's other side. I really wanted a swordfight between them in the end, shoot me.
