Old acquaintance
Still, Sigma decided to put those thoughts aside because, in one way or the other, he probably had to deal with those four guys before, and while he had to deal with those weird problems as well, he also managed to return to the world of the living without any problems. That means that he managed to deal with all the problems they caused before.
"Come to think of it… if I don't have to eat or drink here, do I still get old?" Sigma thought while considering the difference between the time that he was revived and the time that Saria was captured. "The difference between those two periods is fifty years, but I grew around eight years… more questions, huh."
Sigma decided to forget about those questions and then grabbed the enemy's weapons. Making them levitate while he advances would work well as a training in between battles.
