oh, gomen nasai ^^'
I have reading Mermaid Bomber, I'm sorry about that misstake,

I didn't think that she is on the side of Bagura, I mean, this B-1 Grand prix on planet Bomber is only 1 time every 4 years, this is only for fun on planet Bomber, maybe... o_O'
But in episode 48, she was on the side of the Bomberman's, so this could mean she is on the side of Shirobon and the others.
