Is this +96 speed adding to your speed for the attack in the first tech?
For quickness remove the bit about an opponents ability to perceive. As per norm, you can perceive things within your own speed range. Also, there are many more ways of perception that doujutsu alone. Be sure to include upkeep costs for maintaining this jutsy
Counteract would only affect things of equal rank so I suggest making multiple ranks of strength. Also, this attack would be unable to affect anything intangible such as fire or water. Another thing, you wouldn't be able to deflect anything that is faster than you can perceive. This also isn't a raiton tech. It's just vanilla bukijutsu as is.
