YES YES YES YES YES YES!! :KoishiXD:
Orange is a great choice because of how easy it is to learn about her. She only appears once, so you just read those dialogues and you literally know all about her haha. And she's just in stage 1 so it's easy to play the game yourself and check it out :)
As a result, learning her personality is also quite easy. It's always up to personal interpretation, but with lines like "Ahaha, don't underestimate me just because I'm the first stage boss!", anyone could see her as outgoing and likeable. She is practically waiting to be the next protagonist!
Meanwhile someone like Elly or Kurumi, they have more passive dialogues, such as "I couldn't help it! The magician (Marisa) forced her way through ^^' I won't take mercy on you though!". I don't think that's the exact line, but you get that it might be harder to prop up Elly as a heroic character.
Also, earlier today I was coincidentally thinking about a male Orange cosplay (?!). It's surprisingly easy to convert her outfit to be male. She doesn't wear a huge dress like the other characters, so that part is already taken care of. Just shorten her hair, maybe give her cool shades, and you're done!
Once again, Orange would be the perfect candidate for a redesign. She's got so many great qualities :)
...Okay, okay, I admit, she is my favorite character so I
just might possibly have a chance to be slightly considered a little bit biased...
