|Concealed Sword: Swallow Reversal|
|Name||Concealed Sword: Swallow Reversal|
Hiken: Tsubame Gaeshi (秘剣・燕返し, Concealed Sword: Swallow Reversal or Swallow Return) is a kenjutsu technique that was developed by a legendary swordsman, and is currently employed by Reika Masamune, a member of the Seven Ninja Swordsmen of the Mist, who obtained the technique during her training in the Land of Iron. The technique consists of a vertical, horizontal, and circular slash, all done in rapid succession, upon which the three consecutive slashes close in on the enemy from all sides to create a prison, that allows no chance for defence or evasion.
The first strike comes at the opponent with overwhelming speed, creating a circular arc to surround them. After which the slower second strike comes from the above meant to block off escape, and the third and final horizontal strike is to keep the opponent from escaping from the side, thus completely overwhelming them. The Tsubame Gaeshi is a lethal attack that cannot be avoided through typical means, and according to legend it is a technique that challenges god with mere human skill.
If by any chance an opponent manages to block one of the slashes, the other two will most definitely hit, making it an impossible technique to fully block. Due to its close range, if an opponent attempts to retreat, Reika will quickly cut them down. In order to perfectly execute the Tsubame Gaeshi, a suitable level foundation is required, and if Reika does not have a proper foothold, she will only be able to produce the first two slashes.
