Yes, that's why I'm a magician. It's been a while. I keep repeating that it's not always good to try this and that, but I think it's about time I reported my survival to Ryuseki, so I'll raise something up, and for now it's just the same old thing. We've actually tried changing the text a little between the regular version and the second version, but if you like, you can enjoy it.
So, as usual, there's nothing to explain, but it's a monster-making joke that magicians often do. The heroine may have run away during the modification process, and some of her natural skin is exposed, but as a magician, I think this kind of thing is naughty. It seems the brainwashing procedure was incomplete, and there still seems to be some reason left, but even then, I can't resist the evil instincts that have been instilled in me, and ultimately I feel evil. By the way, as a magician, I like scenes where reason and evil minds clash and "gulp" together during brainwashing. It's thrilling to see my personality, just before it disappears, making a final stand. Whether you like the noble appearance of the heroine, who tries to fight to the end, even if it's no use... or you get excited by her aimless appearance, where she can't do anything and her personality is forcibly overwritten. Hmm, well, the magician doesn't really understand that area (stick)
