The fight between Sera and Alex ended with Sera's victory.
Alex sat on the ground dejected; it was his mistake; when he used Time Stop on the Sera behind him, he had let his guard down thinking that he had won. He had forgotten that he only Time Stop on Sera, not the whole arena; if he had done that, then the match's outcome would have been different. It never came to him that Sera could create a clone using her Shadow world; in fact, as an assassin, she only showed her real body when she was sure that she could kill her target; therefore, the Sera who had attacked Alex was not the original Sera, but a clone made using the shadow world's energy, it was a gamble which paid off.
Sera also sat on the ground and leaned her back against Alex's back; she was exhausted.
''Hah! Hahahaha! You have progressed; I knew you were strong, but not to this extent. I was sure that I would lose; it was my thought at the beginning; I was not sure of my chance of winning.''
