Shockwave
They watched Anthony walk away with suprises on their faces.
They weren't new to death, neither were they new to blood.
They were just surprised that Anthony killed another student so casually.
That was all.
They were just surprised, nothing more.
None of them thought of reporting this to the Academy.
Even if they reported it to the Academy, Anthony would only get expelled that's all.
What if Anthony decides to kill them after he gets expelled from the Academy.
They were aware of the fearsome Null family, they didn't have such a background that could match Anthony's or have a connection to such.
Thus, reporting it yielded not a single reward, but troubles only if done.
Besides they didn't even know the dead guy to go to such lengths for him.
Even if they knew him, they won't still report it.
So none of them spoke about it.
