You spoiled nothing, I only had her say she 'knows' how someone dies, that implies others may be dead that she doesn't know about. Also the fact shes from 25 years in the future means it could be a while before said person dies =P
Bleh, I like to apply science when possible, the crazy was mostly brought in by you people, and I never agree'd to the angel, i'm letting Silver get away with it because he is relatively new, and I let you get away with immortals because I did it first, and technically Raike, Miharu, and Josh were already time travelers from the Focus Shift RP so I figured it would be alright if there were a few more.
Energy itself.... I really don't get you on this, I mean, according to E=MC^2 everything is technically energy[Energy=Mass*speedoflight^2]
That last one is flexible logic, its also the reason the A-Bomb works, and why I suspect that through the manipulation of energy and mass alchemy is completely possible although extremely difficult and most possibly not worth it.
But viruses are infinitely complex[literally, you get into quantum science which the bases of means you CANNOT know everything] so even if you use it i'll just go and say it didn't work completely or something along those lines =D
Yue/Yui/immortal!Miharu, right before the missile hit Balice City, changed the plague into...well, it still retains all of the qualities of the actual plague, aside from the fact that the people who are infected and turn into zombies will be able to turn back to normal if Yue/Yui/immortal!Miharu sends out a chakra pulse throughout the Earth. Otherwise, it is pretty much the "plague". Yue/Yui/immortal!Miharu just likes to have a false-safe. Don't worry, I won't actually use it (probably), I just RPed it since it would be something Yue/Yui/immortal!Miharu would do.
I don't get you there...
Anyways, Odessa dn Sarah are off doing something mysterious that I won't actually roleplay until after the fact, so you actually can't have Yue interfere since that would involve bunnying, which i'm not gonna allow with those two characters =P
And the plague still exist, I don't see how Yue/Yui is going to stop it... I already roleplayed it spreading halfway round the world, so its kinda late to stop it.
