This is roji kusano, from the series Muhyo and Roji! and this is one of the costumes i'm doing at gasukan this month!
Its pretty ridiculous with its suspenders, but even roji can be serious business at times! He means well and is always worried for muhyo and he uses a magic pen to write wards to fend off spirits and evil practitioners XD
anyways if you've never seen the series or even heard about it you should check it out. Be warned, the first volume totally doesnt start the best, and the art is different. But if you give it a chance the second/third volumes really kick the action into high gear! it aparently released it's last volume today in japan TT-TT and has a total of 18 volumes!
GO READ IT!!!
