Thanks guys. Now let's get ready for Uverhumans.

Magic is the foundation of Uverhumans, we call the reserve prana.

Uverhumans are basically semi-kryptonians, killing them by normal methods won't work but they aren't invincible. Stab them with a knife, they can survive longer compare to regular humans. 

[quote=What is Prana Shield-Grey]A phenomenon linked to prana that prevents abilities from acting within the boundary of the human body.

The current explanation behind this is that the concentration of prana within the human body prevents external prana from exerting its influence. This is supported by evidence of residual prana building up through what is commonly known as "the prana shield".

Past approximately Level 5, excess prana is capable of creating physical interference through the creation of a transparent barrier. This shield does not begin to regenerate until an individual's prana has reached its max capacity, and can be expended to fuel abilities should an ability user run out of internal prana.

Due to this phenomenon, it is believed that an individual's prana behaves uniquely or otherwise has unique identifying factors.[/quote]
