I...don't think that was entirely true. She never completely admitted she was a virgin nor did she ever imply she was previously engaged or romantically involved before she was a bounty hunter. At least that's what I can devise from what I've seen/read.>>10610623
The OVA is fun stuff, but the manga is SO much better. For the love of all things awesome (and Rally's Cobra GT500) read the manga. Thankfully, they've re-issued all the old TPBs in omnibus form and Sonoda is doing a new manga (GSC: Burst).
