On his swift advance towards Xukhezur, the ex-SOLDIER notices something. It was a slew of objects, possibly no bigger than an orange, taking flight. He's uncertain as to what they are, let alone their nature or properties. But it's to be assumed that whatever Xukhezur's tossing before him is destructive. In light of the unknown, Kuraudo changes his direction by veering left posthaste. Afterwards, he brings the First Tsurugi over to his left side, contrasting its position.
As his path bows, Kuraudo twists the rotation clip with his right thumb and forefinger. It's located beneath the base of the handguard; responsible for unlocking the fusion swords and bestowing offhand swordplay. In addition, it serves as an auto-locking mechanism when an auxiliary brand is inserted. Now that the swords have been unlatched, the ex-SOLDIER veils them with spiritual energy. They leap from the facets and surrounds Kuraudo to fortify his defenses.
By the time he set out a bastion of swords, a number of explosions occurs. It--the shockwaves--breaks the flow of his run but only temporarily. Kuraudo takes one staggering step after another, pressing onward to resume his approach. If it weren't for the swords, shielding him from the blast, the outcome would've been grave.
