KC on Monsterization & Corruption (Via Exet/MGR)

Firstly, about the life after monsterzation.
KC's stance is "as you wish, as long as not counter to the spirit of MGE".
Love conquers all. Even without everything but love, you can still live. MGE is such escapist porn fantasy.
It is not a work meant to make you suffer. After all, everything will be settled at a good conclusion, as long as the settings permit. And it is the main theme of MGE.

From the very first, monsterization may make women lustful or loyal to their desire, or add the instincts of the Mamono, but it doesn't change personality of women so much.

Some may want to have life with work, hobby, culture, sightseeing, or other various activities still after monsterization, and MGE says yes.(Existence of such elements are shown in the books. In this case, KC thinks the priority of sex in their life will become almost equal to a meal)

Some may want to be released completely from the duties of life and indulge in sex, and MGE says yes.(This is a particular case, but quite attractive choice for the people who live in the country where "dying because of overwork like 600 hours per a month" is no joke)

Some may want to release their desire for murder, theft, and various acts which hurts others, and MGE says no.(In such cases, MGs will make them indulge into themselves so they can't think such vicious thoughts. The change of the priority of sex in life is mostly intended in this way. It is not so utterly different from the case when human values are changed. For example, our values change when we eat a delicious dish for the first time. And when we marry with a partner, the priorities of life will change.)

So there is nothing which disturbs you if you want "normal" life after monsterization, except for the fact that priority of sex in their life will become higher. Is it still unacceptable?

Additionally, We Japanese value the contexts of sentences rather than what is written literally.
It is called "言葉の綾(kotoba no aya)". For example, if MGE says "Men who have sex with MGs become impossible to think except for sex with them", it an expression which intends to discribe how attractive the sex with MGs is. It doesn't mean that all of them LITERALLY become unable to think except for sex.(But if they wish, they can do that) This seems to be one of the "gaps" KC tried to explain years ago.

Most Japanese fans understand KC's intent well, and estimate MGE as the ideal world which rejects all "bad endings" by all means. Of course there is some people who dislike MGE as dystopia. But in Japan, most people don't stick around the Doujin works which they dislike, because it is simply a waste of time.

Secondly, about "Corruption element".

Originally it is a minor fetishism that focused on brainwashing, mindbending, netorare, etc. KC likes some elements of corruption like change of costumes and mentalities into more seductive and aggressive ways, but dislikes the tragic endings it will bring. If he was a true disciple of "Corruption fetishism", then "Fallen Maidens" would massacre people cheerfully, stab you, and display the kiss and sex with the villain who brainwashed them to the dying you. Of course KC did not want this. He rather removed brainwashing and softened the fetishism in MGE.

Now "corrupted" girls focus on their true desire and love that they suppressed, and their personalities are liberated or restored rather than warped. (Though there are some changes like becoming lustful or accepting monsterization because of having MGs' value. If they even call this "brainwashing" and hate it, then it can't be helped.)

Wilmarina is a special/particular case. not only her, KC described "Fallen maidens" as the girls who couldn't be redeemed without quitting being human. She was forced to become obsessive about helping others, by letting her bind herself with the sense of guilt, and became the "ideal hero". Her life was always for others, manipulated by others, and now she is released from obsession, and "others". Now she is showing her true nature. I think it is rather the Church and her dad who brainwashed her. I think she already sacrificed herself for others enough, so calling her too selfish is a bit cruel.
