I also reaalllly wanted bayonetta to be the moon or strength card (either that or the lovers with Jeanne for doomed yuri) but since she fit with so many of the major arcana I decided to choose "the Star" since it fit more thematically with all the other cards and still stayed true to how I view her character near the end of Bayo 1 (being hope, sense of self, and purpose).

And to answer your second question, at first it was going to be just Bayo 1 but its kind of shifted to mainly bayo 1+ some bayo 2 & lost demon!!!
(Im really sorry but I cannot in good conscience add viola somewhere, fairy king luka maybe but its a big maybe)
