This is the work of the Korean artist Allesey from Pixiv.
Personally, I think this is an artist to watch for several reasons. He has a great sense of perspective, anatomy, physiology, motion, and action. Plus, he has an incredible imagination and healthy amount of perversion! His skills have improved from when he first started uploading his work, but I've been hooked since day 1.
His main heroine, Cannabis the Witch, is an immortal who takes pleasure in fighting with everyone she encounters which typically ends in sometimes comical and almost always sexual ways.
I made sure to categorize his work before posting his collection here since the Pixiv numbering system helps in no way to distinguish image from image (except chronologically).
Besides his series, works to pay special attention to include his mash-ups of video game characters. They're very inventive and only lend to the notion that Allesey is an imaginative fellow.
On a personal note, I'm proud to also be including a series that Allesey has not posted yet on his Pixiv, "Witch vs Adventurer." This particular fight is between Cannabis and a character of my own, Dierdris Wolfpaw from mine and Labeltornoff's original series, "Tales of Hylore." I'm proud to have participated in this trade with him, and be expecting to see my side of the trade show up here hopefully within the next few weeks!
Enjoy this gallery, and make sure to give credit where it's due! If you like Allesey's work, let him know! He's fluent in Korean and adept in English, so don't be shy!
Loved the fight with the adventurer. It and the most recent one with the succubus might be might favorites. I'm surprised you haven't mentioned this one on the blog.
