Is Kai a girl?

In a recent episode of beyblade watched I noticed Kai was a little big in the chest area. What do you think is Kai a girl?
Here is my evidence:
I think size B at the least...
He's male.
And there's a thread for asking questions about the anime and manga.
You're joking, right?

It's called being ripped. Besides, feminine traits in guys are popular in Japan.

EDIT: Beaten by the Gecko
Oh god this is the best thread ever.

Thank you.
You are a rock.
