I think you're talking about La Pucelle: Tactics, a PS2 game where Jennifer Hale plays Priere who's the main character. I only know about this as Priere is a common reoccurring post game/dlc character in Disgaea. I've never played her actual game though, but it is almost as old as Disgaea 1. This game supposedly had an EN release, but like most NIS games (especially back then) it was probably a very low supply and no one knew about it. I saw Soul Nomad maybe twice in my whole life when I got it used the second time I saw it, and Unlosing Ranger was so niche and unknown that I vividly recall when I asked a person at Gamestop if they had the game they looked at me like I was an insane person.
Turns out when you ask "Hey do you have 'Unlosing Ranger Vs Darkdeath Evilman' in stock?" the person at the counter will think you're insane or pulling a prank.
