Ha ha. This looks awesome. I can't believe all the digging you've done for the party members. For someone who isn't serious about this project, you really have done some serious work.
I also have to say that I'm not homophobic, nor am I gay in the slightest, but when it comes to anime, it's just home base to have guy on guy action involved. I think this would be great either way, depending on the audience you want, but I think, since you aren't hellbent on a serious project, that handing it over to someone once it's done to make a "guy on guy" version would be a good choice. But... again, it's your project, and I wish you all the luck. I'd like to see how serious the gameplay for a game like this ends up being. It's got to be interesting.
