Indestructible Soaring Short Swords is a pair of swords created by the village of Takumi. They are designed to parry attacks and allow the user to freely transform the wind. They also maximize the user's attack power. The greatest advantage of these swords is the minimal use of the user’s chakra to perform powerful techniques, [1] allowing the Fuuton Shinobi specializing to fight for a long period of time without getting tired. The user can also create vortices for flight.
When Hoki took this weapon to himself, he used only one blade. At the same time, it was not visible at all that Seimey wore these blades, which did not prevent him from using their strength.
