Behold the might of the Arseid School! Radiant Blade Waltz!
- —Laura's S-Craft announcement
Radiant Waltz (真・洸刃乱舞 Shin Kōha Ranbu) is Laura S. Arseid's secondary S-Craft in the Trails of Cold Steel trilogy.
Laura utilizes her kenki charging her great sword with light that extends beyond the blade's tip. With her sword powered by radiant light, Laura charges towards the targets in range delivering 2 slashes followed by a full-round swing.
- In the dubbed version of Cold Steel, the S-Craft was still named by its previous name as it was still the same technique. But it was changed to actual name in Cold Steel 2 for unknown reasons.
