Favorite Black Cat Character

For those of you who have read or watched Black Cat you know the series is full of colorful characters, ranging from main characters like Train to supporting characters, like Kyoko the fire maker. Which character do you like the most? Do you like the evil characters, like the Apostles of the Stars, or the main characters better? Which character should get more sceen time? Why am I asking you all these questions?

My favorite character is Eve, the machine girl that travels with Train and co. I love her emotionless personality and ability to create any weapon with nanomachines. I also think she's really cute, what with the long blond hair and all.

My favorite is probably Train or Sven. Their the only characters I remember. It's been over a year since I read whatever few volumes of Black Cat I have.
