Happy Halloween! Have a Mismagius Gijinka, because I haven't drawn Ruri in ages and that's a shame!
I changed his costume to something more revealing for the fun of it. His hair is based on Mismagius's 'hair'. The green mixed into his hakama is to tie that same green into his outfit. Shadow ball is one of my favorite attacks to use with Mismagius, but I had to look it up because I couldn't recall what it looked like...
There are alternate versions available on tumblr and weasyl.
