First off, a real answer IS coming up. I should have warned you, but I'm so used to the fact that all my friends know about this already that I forget to tell you...I'm a crappy correspondent. Everyone who's ever written e-mails to me is aware of this. I suck.

Anyway, I was listening to Obokuri Eeumi while doing my math homework, and was thinking about how utterly well-suited it was for Mugen's backstory. Ikue Asazaki has something magical in her voice that conveys his pain with acute perfection: it portrays his character so deeply and intricately, because really, inside the bratty, egocentric Mugen lies this lonely wasteland which he has to tread every day with, fighting every second to remain sane.

And I think that answers your question, too I like Mugen most, although all the characters surprise me in how incredibly realistic they are, especially Fuu, to whom I can attribute no common stereotype! She's whiney, selfish, a complete airhead and possesive of the people she loves while stubbornly refusing to acknowledge it. She can be kind, but she can also be a complete jerk. She has a strong sense of values which pushes her towards helping people, and makes her very compassionate. She, like all people, just wants to be loved and acknowledged. She's not a hero. She's simply human.
I am utterly fascinated by Fuu. One of the most convincing, multifaceted and REAL characters I have ever seen in manga/anime. A true masterpiece. I could rant about her for ages.

And Mugen is...well, I like characters who are consistently strong and SHOW it. I like how Mugen invariably wins his fights and clings to life with almost animalistic obstinacy. I like his vices as much as his virtues. I like how he never backs down from a challenge, always charging into life like biting a chunk out of an apple, with resolution and pleasure. I like how unafraid he is, and how, despite his bad manners and crudeness, he has a strong sense of justice and is not afraid to use it when he feels like it. Plus, he's unbelievably hot

I like Jin too, but less than the others, probably because Jin himself is not as visible and 'in your face' as his two traveling comrades. He's a bit...bland. Though still utterly lovable!

Kenshin is the next manga on my list I'm coming to learn that I can majorly trust your advice.

Okay, I don't want to sound obnoxious, but I MUST put in use my superior japanese skills (hah...as if!) to point out a slight mistake on your part. Yuki's name is written with one 'u' only, to indicate how it is pronounced. It's crazy how his name fits him though, considering Natsuki only gave it to him randomly. The kanjis litterally mean 'a reason to hope', and yuki can also mean snow or (in the case of 'yuuki' courage. He starts out being cold and insensitive like snow, but with Tohru's help finds the courage to speak up and make friends.
And yeah, Yuki is cool. Him and Kyo have been some of my biggest manga crushes ever. Both of them absolutely kick ass and provide wonderful material for fanfiction or just profound character analysis. But you'll find later on in the manga (if you haven't found already...you've probably already finished the series), that Tohru ending up with Kyo is really the best choice. Yuki just doesn't...see her that way. I don't want to spoil anything if you haven't gotten that far yet, so I'll just conclude with a big 'you'll see'

Congrats on finishing MARS! Was it an enjoyable read?

And you know what? I think, before starting Kenshin, I'll re-read KouKou too. It's just too good of a manga to stay away from long...plus, I need to check for updates!

Anyway, you'll get news from me soon! I'm sorry I went all dead-ish for a while and didn't write :S
