I was very annoyed by Mika...
And same as Maria.
All Maria say is "Brandon!", with the same expression in her face.
And all Mika does is cry and cry.
Kickass move.

I could handle Maria, though there was some awful dialogue from her... "Brandon you don't have to talk, I feel what you're feeling" Yea that had me laughing my ass off.
But Mika was a *beep* annoying brat, I hated her guts! One of the reasons the 2nd part of Gungrave made me lose my interest in the anime.
