Age: 12 (both)

Both children are highly skilled at using their chosen weapon.
Background info: Mireille and Mischka were Natalia's two abandoned children. After living at the orphanage that their mother left them at when they were very young - before they even had proper names - they ran away, seeking adventure. It is unknown what - exactly - happened to them after that, but - since then - they have grown into a pair of highly skilled, highly sadistic killers. Seeing them now would surely put their mother in tears.

If your idea is boring though, and that's why you're easy to distract...well, that's a really fantastic reason for not being able to focus on the task at hand! In that case, head back to the drawing board. And again, don't give up!"- Marjorie Liu, NYX: No Way Home interview
"Really? That's INANE. Most people in life don't HAVE great power, and the few that do are almost NEVER responsible with it. The people who have the greatest responsibility are the kids with NO POWER because we're the ones who have to keep everybody else in check."- Gertrude Yorkes, Runaways (vol. 2) #11
