This reminded me of Rance in several ways from the MC to the bad guy who was similar to the bad guy in Rance 2 to the ending with space which was like a reference to Daiteikoku which itself had a cameo of Rance in space.
Welp, another series I wished were longer, although I understand making short series due to how much work these artists have to put into these mangas. It was expected but at least this culminated in Tomaru giving herself for the sake of her colleague.
Uh, ... so, In The End, everything was simply the *a-hem* machinations of the original alchemist, who also harbored a desire to *a-hem, again* engage the Harem Route with his creations.
*crickets chirping*
Won't say anything more that might spoil things for new readers, except:
Thanks for the fun series Minamino Sazan. Pages 24-25, glorious!!!
Again, only in hentai would you read a story about how an ancient alchemist spent his entire life making a harem of artificial, milf succubi only to grow old and using black magic pours all his memories and will into a dick ring biding his time for 600 years waiting for Ooguma to come to the island and take over his body only for the harem of Succubaculus to defeat the alchemist who turned out to be a virgin who just wanted to experience a woman and finally ending with world peace and space travel. (I should of figured when I saw this was made by Studio Trigger that we were going into space.)
"Give him back!! He might not be much, but I still wont let you take him!!"
Shout out to the MVP of this series, Yuu. It takes a lot to put up with Ooguma antics.
