Was going to buy one of Hachi's H-doujins, but my bank didn't like dlsite and they don't accept paypal for adult material, so I grabbed this one instead. Enjoy.
Been wanting to see this one for awhile, thanks for taking the trouble to upload it! I have a general grasp of what this series is about : A mad scientist created three special girls, each with unique abilities. One is extremely well versed in artillery, one can use magic, and one can control machines.
