Yoh Asakura 

Yoh listened to everyone but just as he was about to speak up again Ruby jumped down off a building and landed in front of Yoh, she then thrusted her sword in his face, it was inches away from his forehead oh didn't even flinch he just stood still with a smile on his face. 

"Hi I am Yoh nice to meet you but if you would just give me a second I believe I can address some of your concerns."

He then tuned to face the group again 

"First of all I never said kill, I know some of you may be against killing and there may be a way to take away his powers like he did to us if we can we can simply imprison him for his crimes but the simple fact is he is a threat to every living thing in this world second I think you are both underestimating yourselves and overestimating the emperor. Yes we lost 20 years ago but it wasn't because we didn't have enough power or allies, or because he was to strong. It was simply because we were not ready, we stood against him when our powers first emerged. We didn't know how to use them properly, we lost because we were over confident and arrogant. We assumed because we had the power it was our destiny to stop him but the reality was it was simply our destiny to help and prepare the true Chosen Dreamers and we have had 20 years prepare for this fight and not only have we gotten stronger but we can help you learn to control your power. We wont make the same mistake twice, we can win and with your help we will win. I have no doubts about that and if you hear us out and see what we can teach you, you wont have any doubts either."

He was bluffing slightly as he knew there was no grantee they could sway all there doubts, he then looked right at Heloise 

"For example you said you where psychic like me but you cant fully control it and are currently limited to moving objects with your mind. Well I can teach you how to read minds and how to attack and defend yourself and others with out using your ability to simply throw things at your target with your mind and if you are the Fire Chosen Dreamer I can teach you how to control the fire element however if you are a different Chosen Dreamer I will not be your mentor but I can still teach you how to control your psychic powers.
