Burittsuai Zōdai (ブリッツアイ増大, lit. Blitz Eye: Augmentation) is a personal supplementary jutsu that bolsters the users physical abilities through the use of a sustained electric charge using lightning-release that stimulates the muscles in order to make them stronger via contraction. Those who use this as a method of training have naturally higher levels of strength when compared to other non-Burittsuai users. Those who utilize this jutsu benefit from muscle contractions that are up to 30 times more powerful than normal voluntary contractions, leading to enhanced muscle strength and improved muscle recovery compared to normal muscle contractions. This results in enhanced physical performance in fields such as Taijutsu, Kenjutsu and speed-related techniques because of the naturally stronger muscle strength of the individual, whose muscles are used predominately in the utilization of the above skills.
