Umm...
Although that was interesting, you still need to learn the "facts"
1. Seppuku is a Japanese word for ritual suicide, and was NOT created by ninjas, but by the samurai warriors of feudal Japan.
2. Another word for Seppuku is <b>Harikiri</b>, which literally means "belly slicing"
3. Seppuku was not meant to make you look like a "Baddass" it was meant to die with honor after losing a battle, wheater you are a Samurai or a <b>Ronin</b> (A swordsman without a master).
4. Seppuku is done by kneeling on the ground and slicing your stomach open with a Katana, or more often, a <b>Tanto</b> (Japanese dagger) while an assistant, usually a close relative of friend cuts off your head with a <b>Wakasashi</b> (long sword). It was ritual to have the head removed that way the person would not cry out in their final moments.
5.However, the honor was short lived because after your <b>zoki ishioku<b> (death), you are easily forgotten by many people besides your family, and your <b>meinichi</b> (death anniversary) is easily forgotten
THAT is Seppuku (se-poo-koo)
