Please tell me theres a story behind this. cause it's intresting looking and you don't see much chen and sanae together or chen with a machine gun.

Looks like some mooks are about to get rolled.

I just spotted an error... both Saneas feet are on the right side of the bike, but her feet are still on the pedals. sure she might have stuck her foot through the middle of the bike, but she woyldn't be able to pedal and the bikes in motion. Error, you decide.

Sanae doesn't seem to put her right foot on the pedal to me. Although I think the bike is going to fall over.

And, yeah the machinegun bike is cool. I'm gonna install a support on my bike tomorrow :D

Stop letting yourselves be restricted by common sense.
