Future Trunks uses this attack during his brief sparring match with Goku in his Super Saiyan form. After both warriors transformed into Super Saiyans, Goku comments that he and Future Trunks look exactly the same. Future Trunks says "Let's find out" as he prepares to attack Goku with the first slash. Searching Future Trunks' feelings, Goku decides to stand still, knowing that Future Trunks will stop the attack. Promising that he will not stop, Future Trunks then attacks Goku with the rest of the slashes in the rush and Goku effortlessly blocks them with just one finger.
