Okay we have:
Kirali Kira (Ultimate Swordswoman)
Ashlin McGuffin (Ultimate Midwife)
Christian Uril (Ultimate Artist)
Jessy Harime (Ultimate Café Hostess)

I could see K breaking a rule and get killed by Monokuma. Maybe trying to get one of the hostages. And the rest could be killed in a double murder. Or I could just permanently take one character. I think Ashlin could be fun because she is more fragile, and expandable. That is if you're all fine with it.
