Foul play
Santino's departure was just as sudden as his arrival, and it was almost unbelievable. It was not that Shera was sad about it; she was overjoyed, on the contrary. It just seemed too good to be true. After all, she was preparing for a war that would probably last at least a month when the man decided to leave on his own volition.
For a while, she did not lower her guard and prepared La Rose Noire just in case that idiot decided to attack when they were not ready.
However, weeks passed and there was no move from his side. He seemed to have vanished off the earth's surface, which was the best outcome for Shera and Leo.
Once they were certain that Santino would not attack any time soon or not attack at all, they spend their energy on their companies.
