Talk:Korosensei VS Sebastian Michaelis/@comment-28388151-20160728134426

This is going to be a bit a spoilers. Ultimate defense form does have a weakness that was mentioned in the show. It takes a moment to charge. That's why the snipers felt guilty for failing to make the killing shots. Sebastian is likely fast enough to win in that moment if Kuro-sensei ever attempts it, he is faster than bullets. Though, if they're both moving it's honestly hard to say which of them is faster, its practically the Flash vs Quicksilver. Technically the moon explosion wasn't Kuro-sensei's feat, he just stole credit. But it is what will happen to the earth if he's not killed by the "due date".

It is pretty costumary for Sebastian to procure any weapon he needs to get the job done. He has killed children and threatened mobsters. So weaknesses could be collected from interrogation. Even in a fair field where all of these advantages are taken away from Sebastian, its not that Kuro-sensei is invincible to physical damage. He's been stabbed through the heart by tentacles. So a blow with equal strength is enough to break through his skin. The only question is whether or not he can hit as hard.

As for Kuro-sensei's advantages, he doesn't actually need to be as faster than Sebastian. Kuro-sensei has already proved he can deal with opponents that have that advantage. Kuro-sensei is also an assassin, so he's not limited to frontal assaults. Essencially, any technique we saw in assassination classroom, Kuro-sensei could likely replicate. Lastly there is that beam attack he used, it was too fast for someone faster than him to dodge, so Sebastian couldn't get away.
