Hello someinheritthewealth, and thank you for the interest.
I'm going to have to say no to bringing in a different character from a different series. You can use their likeness in an original character, but so far, other than characters from the Discipline series, all other characters are original builds. Part of the reason we do this is to avoid any characters inappropriate for the game, like those from series that have supernatural powers, for example. Plus, people may not be familiar with the series.
Also, by wanting to play exclusive lesbian, you would be limiting yourself to a very small portion of the game, but the other problem is that there is no room for a totally dominant student. There is a certain hierarchy to the series, one that puts the Morimoto family in control of the school, and most characters simply can't get away with doing things their own way. They may be allowed to do things, but that would depend on you being okay with stepping out of a dominant role from time to time.
