Byakuran laughs at the next technique he is to learn, but he performs it anyways once the clone is made. He simply channels earth based chakra on his skull so it takes on the hard and sturdy properties of earth itself. Once the clone runs towards him, he takes off like a bull, head frontwards, and collides with the clones chest, causing it to disperse.
"That one was very basic, in my opinion. It's cool because you can actually use this with elemental ninjutsu, but a disadvantage to that is its only capable of defending against D-ranks. I also don't like how you expose yourself so much - using your head as a means of attack makes you extremely vulnerable, and you are basically dead if they hit you at such close range. Also, you kind of have limited vision if you have your head ready for a headbutt. Sorry, i had more disadvantages than advantages, haha... Anyways, I would use this when my opponent is mid air, after a tai technique that launches them mid-air. They will have trouble defending against a headbutt with added strength if they are in mid air."
The clone approached and Byakuran assumed a stance by crouching downwards, ready to race towards the enemy. As the clone neared, Byakuran pushed off with his legs and dashed to the enemy, all the while channeling wind based chakra on his left arm. Once the clone and Byakuran met, Byakuran pushed his wind-coated fist in an upward motion to the clones stomach. This strike is augmented by wind chakra and causes the clone to fly off.
"I like this technique because it is a nice way to make a gap between two enemies if you were to opt out of a close combat spar. It also does not make you vulnerable in any way because its just a simple punch, so you are just free to defend and to dodge if the need arises. Forcing the opponent to fly several feet is also a good use for this technique because it makes them very vulnerable. I'm sorry, but I cannot think of any disadvantages for this technique.. In regards to combinations, I would use this with the earlier headbutt technique once the enemy is mid-air. I think the two complement each other well."
As the clone approaches close-range, Byakuran lowers his body and begins to spin as he moves forward towards the clone. Once he is within one meter, he rockets upwards, performing the uppercutt to knock the clone to the ground.
"Well, this movement seems hard to execute. I don't like how you're spinning around because there is a short time span where you do not face the enemy, which is basically your vulnerability. I also think that its lack of chakra infusion makes it a disadvantage since it is not as powerful as other techniques and won't have extra effects. But, the advantages are pretty great. Since its an uppercut, it can be performed rather quickly. Additionally, the spinning motion would make it difficult for the enemy to make contact with you and you can use it to divert physical attacks away from you. I would use this with the crane kick. I can deliver a quick kick to the enemy's face through the crane technique, and the kick should push the enemy back/force his head back. I would use the small time frame to spin quickly and deliver an uppercut just as the enemy is recovering from the first hit."
