CROSSOVER REINCARNATION AU

I, René Enjolras, born in Arles in 1815, died in the faubourgs of Paris in 1832, childless.
Once leader of a revolutionary group of university students.
Now resurrected by decree of the Lady of the Underworld, to aid freedom fighters during occupation.
The French dream that once came true, after our sacrifice, is now once more endangered.
My call: to gather the reincarnations of the other Amis and the descendant of Marius. To encourage them to fight back. To expel those who call themselves Nazis from our lands.
But... what if someone disbelieves?
And... what if someone was reborn across the borders, among the enemy?
