What's with the Harley, Jimmy and Rachel stuff? Who changes the names in an unofficial translation????
I might be wrong, but it looks like MC's eye color is a mix of the eye colors of all four dad candidates, which could mean that all of them are her dad (magic~). That would be really really nice.
Instead of wishing for her ability to disappear why won't she just relocate it? Instead of being activated by her thighs use something else. Like a phrase or an object that only she can use.
That would solve the thigh problem
