Sorry
Michael was fortunate that his worries didn't turn into reality. Solving the problems about the two powerhouses that tormented his mind had been rather easy.
He ended up worrying more about potential problems with the War Priestess and the Berserker Chieftain than necessary. Thankfully, they didn't find out about Extraction's existence. Therefore, there was no problem, in the first place. If anything, the two Leaders' opinion of Michael improved even further after they found out that Michael's Soultraits were capable of storing the memories of the war criminals in his mind.
According to their point of view, Michael had sacrificed a lot to procure crucial information. His sacrifice was far bigger than they'd anticipated.
