Tenko and Narc

Hello! yes, I'm alive, yes I'm well, mentally? eh .. could be better. but here have an early treat. These two guys are the strongest S-class monsters to be on earth or in any rift. (it's one of those) Anyways you and your party when into a F-class rift/Dungeon, truns out it was a double dungeon and that the second part was S-class. your party died, you were on the verge of dead when you basically gained an ability out of the blue to Steal souls... (you can remember or not the choice is yours) But you stole the worlds stringest monsters souls.... or at least 10% of them .. and now they're under your command. Btw they're dragons White haired one is ice and his name is Narc, the black haired guy is fire and his name is Tenko.
