Hi Leandra, and thank you for the interest.
In regards to your questions:
A) We like a reasonable posting rate, but this isn't always possible, given everyone's different schedules. We also put a cap on how often people can post to prevent scenes from running away, though we don't really seem to have that problem too often. If your posting rate is well-communicated, there shouldn't be much of a problem, but bear in mind: if you know you are going to be absent for extended lengths of time, we'd prefer that you not engage into long-term scenes that could hold up the game. We reserve the option to remove your character if extended absences are frequent and not communicated.
B) Knowledge of the Discipline series is always nice, but not required. You can get most of the information from the posts and info thread, and it isn't hard to find some info online about it. You can even find the episodes online. With that in mind, we are still trying to remain in the series setting, so Haibane and I guide the game along those themes, since we are more familiar with the franchise.
C) I'm not sure about the transfer student. We have several already, but none of them see much action as NPCs, so I think it would be fine. Being that the school is set in Japan based on Japan's culture and customs, you'd have to learn some things, as we all did over time. We just can't insert a European character into a Japanese setting and simply ignore the culture clash. You would also have to adjust your character premise. The Morimotos should have more leverage over the father than he does over them (ie, he should not have any information on them that could be used against them).
D) No, they do not. All they know is that they are attending a new school. Publicly, St. Arcadia is one of the best schools in the country, if not the entire world (though we really haven't mentioned that) and has only recently begun to accept male students. To some, a transfer to this school would sound like an amazing opportunity, whereas some might consider it only another inconvenient transfer. When they do arrive, they may be taken aback by the sexual rampancy, or embrace it, depending on their character type. Typically, we like for students to embrace it, as this allows them to get more into hentai-based fun, which is a bulk of the game.
E) The overall character type sounds like it would work. Except for maybe the virgin part. That would quickly become irrelevant upon enrolling in the school, unless we could work something into it (example, constantly kept in chastity).
Haibane is kind of touch and go through the weekend I believe, but she may have some input too.
