Okay, so you have decided to commit a good old fashioned ritualistic Sepukku.
Step One: Find, and provide yourself with a sanatized knife of some sort. (We do not want infections to catch on to those who will be dragging your body out)
Step Two: Proceed to place the knife at the bottom right section of your stomach. Slightly four inches below the ribs.
Step Three: Take a deep breath, and plunge. Then proceed to quickly drag the knife in a horizontal motion across the stomach.
Step Four: After reaching the second point with your knife, proceed to move the knife in a diagonal fashion to the top right of the stomach.
Step Five: The final part of the basic Sepukku is moving the knife in another horizantal fashion to the left abdomen.
Congratulations! You have completed your first Sepukku.
