Anthropomorphosis Spell

Difficulty: 1 out of 3
Mana Cost: 1 out of 3

A spell for hiding the distinguishing features of a monster such as horns, tail, etc. and mimicking the appearance of a human woman. “Harpies (Encyclopedia I)”, who have bird wings instead of arms, can transform their wings into human arms with this spell, and “mermaids (Encyclopedia I)” who have a fish tail for a lower half, can also transform it into human legs with this spell, enabling activities on land.

All of the monsters of the present are closer in appearance to humans because they are endowed with the nature of an inma, so this spell is highly suitable for all of them, and many monsters have used it to slip into human nations and pursue men. The external appearance is all that can be changed, and mana, behavior, and so forth, cannot be disguised. In the case of races that don't have human legs, sometimes they even walk unsteadily until they get used to them. Most humans won't catch on to their true nature since they can have looks that appear perfectly human. But in some cases, those such as people with good intuition, who are extremely rare, and skilled magicians can sense that there is something off about their mana. Since monsters have an excellent mana sense, a monster would realize right away that she's dealing with a monster like herself even if that monster had changed into a human using a “anthropomorphosis spell”, but among races who specialize in this spell, and superior casters, there are also those who can disguise even their presence and mana as human and do it well enough to deceive even monsters.

One cannot change into whatever form she pleases using this spell. The caster's looks basically remain the same, but her monster traits are swapped with human traits, for instance: inhuman skin color changes to be the same color as human skin, parts that humans don't have such as horns, tail, etc. are hidden, the monstrous lower half changes into human legs, and so on. Despite the assumption of a human appearance, superhuman beauty and charm is retained, spells including “seduction spell” can be used, as well as a monster's special characteristics, so she can seduce human men no problem; however, the “anthropomorphosis spell” will break should the caster receive intense pleasure or ecstasy unless she has an extremely high aptitude for the spell or is a skilled caster. Thus, it's basically impossible to maintain this spell while engaged in copulation with a man, and even just being head patted by a man results in so much ecstasy that it may sometimes cause the ears, tail, etc. to inadvertently appear, but being in such a situation means that she's already charmed the man and stolen his heart, or that she's already brought him back to her bedroom and become physically intimate with him, or maybe even that they're already right in the middle of sex, so in such cases, it usually isn't a problem since the man would have already been made to taste the pleasure of the monster's body firsthand. In fact, if anything, revealing one's true form from human form mostly enthralls a man's heart even more as the lewd, bewitching, devilish charm of a monster is in full force in her original form, and the transformation accentuates it.

The inma of yore used to use a more advanced transformation spell of the same school to change themselves into the ideal women of the men who were their prey, but unlike the inma of yore who only sought men as “fodder to be consumed in a single night”, the inmas of the present seek men as “partners for life”, so it would be meaningless to charm men in a makeshift form. Naturally, this spell stopped being used as a result.
