Shukuchi - "Reduced Earth"
This is the fastest technique ever created. It is named reduced earth because it looks like magic was used to close the distance. It moves so fast that the naked eye cannot register it. The work of the legs is so powerful that the ground gets destroyed everywhere you move.
The shukuchi is so fast that it can even be performed up walls. The constant movement of your legs allows you to climb up a wall and even move across a ceiling for a short time.
Shun Ten Satsu - "Instant Heaven Murder"
This move does exactly what it says, instant murder. It combines a charge with the shukuchi and a battou-jutsu of the tenken. It is so quick that you die instantly and feel no pain. The only thing on the same level as this is the Hiten Mitsorugi ultimate attack.
