Yeah, Rachel has nothing worthwhile to offer in and of herself. Even her Irregular (as in 'not a resident of the Tower') status is worthless, as being unaffected by Zahard's immortality doesn't mean anything when you're an ordinary human with absolutely no method of harming him. He's still a 2 and a half meter tall superhuman who makes monsters like Yuri look like particularly weak babies after all.
I suppose you could say her worth is that she's a necessity for the plan of killing Zahard as without her there is no Baam, but even that kind of lost weight when Baam started putting similar value on so many other people.
