Kazuki was having some strange heart issues so he had decided to take a stroll into the glaciers a bit for some fresh air. However he could not have known that his heart issues were that of his seal that was placed on him by his teacher was breaking. Some strange illness has been going by recently that turned perfectly fine shinobi into mindless killing machines. Kazuki however tried his hardest to avoid this.
"Cough, cough, cough.... Whats... happening to me?" He shouted falling to his knees. He was coughing up blood as he grabbed his head painfully and yelled. His body let out a massive explosion of chakra that could be seen from the village. At first it was his normal chakra shining a blue radiance however it started to get darker and darker untill finally it became black.
"I have awoken. Eman sempai I will finish your dream and destroy this world to create one of my own" He laughed as he became that of a changed man. However getting this out he returned to his origional demeaner in order to fool people to believe nothing was wrong. The aurora village would be first to go.
