Guitar Ninja

(From wikipedia the awesome place to put any information no matter how bullshit it is)
A guitar ninja (ギター忍者; gitaa ninja) is a ninja who has learned the art of playing the electric guitar under the guidance of the legendary ninja, Ongakumaru (音楽丸). It focuses on the art of being able to play the guitar without being seen. Guitar ninja are known for their propensity to save the world and supply background music to those with Real Ultimate Power.

The ranking structure of the guitar ninja goes as follows, in ascending order: white belt (白段位), green belt (緑段位), pink belt (ピンク段位), shred belt (寸断段位), awesome belt (大寒段位), epic belt (叙事詩段位), and finally, rock god belt (ロックの神段位). Rock god belts are believed to know everything there is to know about the arts of the guitar ninja — Ongakumaru himself is a rock god belt, and is said to be so proficient at the art that nobody in the world has ever seen him play.

Rammstein's Richard Z. Kruspe, the only confirmed guitar ninja.Currently, the only confirmed guitar ninja is Richard Z. Kruspe-Bernstein of Rammstein. However, he is only a whitebelt because he is, in fact, confirmed as a guitar ninja. However, his status as a guitar ninja has come under fire recently, as he has not actually performed any guitar ninja techniques other than playing really, really loudly.
