Heavenly Body Tattoo

This is the name of the 'tattoo' that Angra Mainyu possess on his chest and Makura possesses over his right eye. Upon its activation, Angra Mainyu's body will be enveloped by it, and be sealed inside a layer of red, in which Makura will break out of bearing the tattoo over his right eye. The 'transformation sequence', if it can even be called that, is somewhat ghoulish and is nothing short of horrific; it resembles an embryo forcing its way out of the womb by tearing a gigantic hole in it.

When it's activated, the Heavenly Body Tattoo will greatly increase the user's chakra supply, whilst enhancing the effects of tai, nin or genjutsu they may cast afterwards. Even when the tattoo's influence is deactivated, where the same 'transformation sequence' will occur only with the two involved having their parts swapped, its buffs will still remain. This allows for it to be abused, however the fact that half of their powers will be sealed away when in a specific form makes to difficult to use it impractically.
