What is Ninjitis?
1.
An STI that slowly overtakes all brain function and at the same tame amplifies many specific brain waves. These brain waves increase hand eye coordination, motor function, reaction time, and overall lethality. Through lab testing this dreaded infection has proven to leave the afflicted with an overwhelming desire to hide in shadows while wearing all black. The disease was named "ninjitis" because in extreme cases the afflicted have been left with an additional need of seeking training and becoming a full ninja.
I think Kyle has ninjitis. I never see him anymore and he's always wearing black.
