Here is a special move of Iaijutsu. It's from anime and one of the ones that I like called "Samurai X" (Rurouni Kenshin in Japanese)...
A little background is in order. Kenshin is the last surviving member of his family (and village) who all get killed during a massacre... A lonely stranger (Hiko Seijuro) picks him up and takes him under his care. Hiko is actually an exponent of the hiten Mitsurugi ryu (a kenjutsu art that specializes in speed attacks by training the person to achieve god like speed). Under the careful tutelage, Kenshin grows to be a master swordsman. The entire anime goes about Kenshin's life, but there are two special moves in the Hiten Mitsurugi Ryu. One is called the Khuzu-ryu-sen (9 headed dragon attack). It involves using god like speed to attack the 9 critical points all at once. It is almost impossible to defeat.
The only way to defeat it is by using the strongest attack of Hiten Mitsurugi called Ama Kakeru Ryu No Hirameki. The reason I post it here is because this is an Iaijutsu. It uses godlike speed to attack the Khuzu-ryu-sen even before it has reached the individual
Here is a vid where Kenshin learns it.
According to the anime you must have the will to live if you're to succeed in using Ama Kakeru Ryu no Hirameki. Anyone faint of heart will only end up slicing themselves first. The move involved putting your sword foot forward so as to get closer to the opponent and then unsheath your sword at a dazzling speed! It is usually the other foot that is used to step forward because using the sword foot puts it dangerously close to the sword and you run the risk of cutting yourself up!
