Blade Runner

Blade Runner  is an artifact used by Rip and Latla.

Overview
Blade Runner is a pair of knee-length metal boots. The boots are styled similarly to medieval full plate armor, with interlocking plates and a filigree design around the edges.

Blade Runner's ability is to create large semi-circular metal blades when the user kicks with the artifact, which then shoot forward toward a target. The size and speed of the blade depends on the arc and strength of the kick. There appears to be no limit to the number of blades that can be created at once.

During Rip's clash with Seal, he has gained enough mastery with the Artifact to make the blades come back like boomerangs.

In the 101st Loop against the UMA Sick, Latla and Ripare able to merge the two together for an even stronger slash.
