I don't think Samurai would go free. He seems to care about the vampire girl and I don't think he'd just leave her there. I can even see him reviving her if she died.
So those two are just the same like Kaze/Takeshi. 100 points are only good if they both get them at the same time. If not, they can't choose freedom to not leave the other behind.
But I don't think we have to spend that much time thinking about 100 points for a Tokyo member. It's not going to happen this mission. Oka will kill Nuri, and not one of team Tokyo.
Reika, Kaze and Kato would probably revive Kurono with the points. And he isn't gone long enough in the gantzverse (although he's gone since over 1 1/2 years for us) to come back yet.
Cherry'd probably revive Sakata right away, so he'll get some time to let go before he get's 100 again.
That leaves only HS really. But I don't think he can get close to Nuri without getting blown up.
But maybe it's possible, who knows. Nuri could change shape yet again and that could allow team tokyo to get close without getting blown up. Kurono might not be revivable. Or he'll be revived and just live outside of Gantz without being part of the story (forever or just some more time).
There are many possibilities, but at the moment I can only see Oka scoring the kill.
