Do you have more information regarding the news that mappa is collaborating with other studio to animate OPM?
Hearing that news brings me smile knowing how freaking crazy the manga is!
if i were to give my opinions.. i think madhouse and probably mappa are the only capable studio to produce the anime for and if you want to know why just look at the panels of OPM..
JUST LOOK AT THIS!!:
Of course these are just some of the many and more panels that i hope to be animated by the anime studio faithfully~
