Sensei

Sensei is a Karateka that has earned a black belt. There are many degrees of black belts, from first to tenth. It's not easy to become a Sensei; if you train every day, it takes about six years, and if you don't train every day, it takes alot longer. A good Sensei will help you get do your moves correctly.

Note that you must go through being a Sempai before becoming a Sensei.

Also, to become a Sensei, you must be at least 16 years old. If you aren't but still know your kata, you can become a Junior Black Belt, and must be tested at 16 for your full black.
