Fana is probably my favorite character among the ones I've played in these RPGs. She's an experienced adventurer and mage who really
enjoys her line of work. She's mischievious and flirtatious and unlike Raidy she's not at all shy about liking other girls. Her behaviour towards Raidy could probably be described as "teasingly dominant." Due to the impression the first image of her left on me I've always started games involving Fana with Raidy coming across her while she's bathing.
Mirabelle is also a mage, but it younger and less experienced than Fana. She's part elvish. I generally think of her as being a bit of a thief as well as a mage. I'm a little unsure whether she should be a good girl or a bad girl. One possible scenario is that she's desperately trying to buy her sister's freedom and Raidy agrees to help her rescue said sister after catching and punishing her for attempted theft. On the other hand she could also be in it to get rich and suggest Raidy work as her bodyguard after rescuing her from a troublesome situation in a dungeon. She could even be a lovable traitor type who isn't entirely trustworthy.
There's a few possible scenarios for this as yet unnamed girl. She could be an inexperienced Paladin whom Raidy rescues in a dungeon -though I'm personally not so sure about playing such a weak character. Alternately perhaps she's a more competent warrior who is after the same goal as Raidy, but mistakes her for one of the baddies and ends up fighting her. She could potentially defeat and "punish" Raidy then end up apologizing and teaming up with her later after she finds out the truth (possibly after also getting captured herself).
