Anyone that uses ninja shit to steal or hurt anyone in present day times. They are masters of destruction and normally operate at night but are known to ocassionally come out in the day if a "Mission" is deemed to be worthwhile. They are often considered to be normal in school except they have no after school activities so they turn to vandalism to fill the gap. They are masters of video games and computer systems and range in physical abilities normally fairly fit because of the things they do. DO NOT FUCK WITH A NINJA
1.) A bunch of ninjas tagged the school last night
2.) A fucking ninja slashed my tires now i have to walk cuz im a fag
3.) I lost my wallet when I left it in my locker, god damn ninjas G'ed up my shit
4.) Konrad bosselman and Robert Long are the most famous known ninjas disappearing after a store heist
