Forget those cutesy bento boxes! Here's Ichi the Killer bento box by Sakurako Kitsa:
This is my obent-ode to Ichi the Killer, one of the most awesome, extreme movies in the history of ever. My rendition didn't do Tadanobu Asano the slightest bit of justice (you try making him out of turkey and mustard), but I think it came out okay.
This is from the very memorable part of the movie where he inhales deeply on his cigarette and blows the smoke out the slits in his cheeks.
