Photon Edge

The Photon Edge is Mari Isurugi's only melee weapon in Hazard ReBurst.

Design
The Rave Calibur Type W-S is a futuristic longsword akin to the Rave Edge Type C, though with differing dimensions. Unlike the latter, the Type W-S has a blade that splits in half to project a larger blade made of Rave Energy. For Mari, the Rave Energy is a green-ish yellow. The sword itself is a white and gold longsword with an angled crossguard, an emerald embedded in the center of the crossguard, a folded-pattern handle, and a spiked pommel.

Capabilities
Being a sword, Mari uses the weapon for close-range combat when applicable. The energy blade can increase or decrease size at the user's behest, allowing for a variable blade size. It can even shut off and close up so Mari can use the sword's physical blade if ever needed. In addition, the energy blade can be discharged as a spear-like projectile to extend the range of thrust attacks, a crescent-shaped wave of Rave Energy infused with light damage, or it can shift into a scythe-like form if spun rapidly in a circular formation.

Trivia

 * Its design is based on Mythra's sword in Xenoblade Chronicles 2.
