I'm quite certain this and the 2 previous images in /gusutafu arent his drawing at all. None of the source links work, it doesnt look like his style and his fc2 blogs dont list them.
Not sure how to embed url so here's the link to his blog: http://teromere.blog105.fc2.com/

All of the mentioned images are gusutafu's work. You may not see them on pixiv and/or fc2 because they're old work from roughly 2 years ago.

They're all on his blog. Click the source link.

oh, i see them now. They now point to the blog page instead of direct image. You were right, seabook, these were very old images. It's interesting to see how his drawing changed.

I get the owl bit, but what's with the blood?
Can somebody fill me in?
