Hienken (Flying Swallow Sword)

The secret of this technique was build off the backs of 107 people, all slain in the pursuit of perfection. By unsheathing the sword at an almost godlike speed, this fanciful skill in no time allows user to strike the opponent three times unexpectedly. The moment opponent enters user’s range it is all over. They’ll be killed in no time. User’s range is invincible.
