Flying Thunder God Technique (Keam2637)

The Flying Thunder God Technique is a Space–Time Ninjutsu created by the Second Hokage, Tobirama Senju, which allows the user to instantaneously transport themselves to a previously marked location. It was later perfected and became one of Yuuichi Uzumaki's signature techniques after being taught the jutsu by the Fourth Hokage, and is still his to this day.

Overview
In order to activate this technique, the user must first place a special seal or to mark an intended destination. After this is done, they can at will enter a dimensional void that instantaneously transports them to the location of the seal. The mark can be applied to almost any area through brief physical contact, including an opponent or other surrounding feature. Because this technique is able to affect anything that is in contact with the user or somehow connected to their chakra, they can also use this technique to teleport other objects or people, though the size of the object and the distance of the location dictates the amount of chakra required. As Minato also noted, the marking formula never disappears from a marked target.

Yuuichi Uzumaki
As similarly to Minato Namikaze, the most expert of all the ones utilizing this, before him, Yuuichi's extensive use of this technique for quick kills and surprise attacks has granted him the nickname Swift Bladed Assasin, due to him normally carring a blade with himself almost all the time, and also his expertise in using the jutsu to maximum benefit. Moreover, for increasing the chances of an attack landing, Yuuichi'll normally use this technique to be the main way of teleporting himself to the enemy, making it act as a cornerstone in his fights in the process.

In the past, Yuuichi also tried to make the jutsu itself go a step further by cutting out the fact that a marker was needed in order for the user (or in this case himself), to be able to teleport anywhere they wanted, but the attempt, despite even having received Minato's help, failed due to the unreal difficulties present.
