I think for me it is that laziness, mixed with how many comics I read online as it is. I read the weekly chapters for a few other manga as they come out (I buy too though before anyone can thwack me for that
), not to mention forum time, so finding time to make myself read a full thing (even short ones like this) are hard for me.
TMNT and Japan definitely interests me though. The idea is so Japanese to begin with, even beyond the ninja stuff. I mean...walking, bipedal turtles, fighting...that just sounds like something weird Japan would come up with to me LOL.
