Kei Machida Trick
Yo! Now, remember during the arc where Kogarasumaru was being formed, remember when Ume introduced Ikki, Ringo, and Buccha to a friend of her's, Kei Machida? She's the woman who ended up making the design for Koga's emblem.
A while back, while watching an anime episode, I saw the credits. It turns out that there truly is a woman called Kei Machida IRL, who really worked on Air Gear and created the emblems. I just thought it was pretty funny how she actually was recognized in Air Gear for her work on the emblems.
