Omen

Raven's Sword is Raven Branwen's signature weapon.

Description
Raven's weapon is a long, single-edged, one-handed sword of Japanese design, with a trigger built into the hilt and cross-guard rather than the traditional tsuba. The scabbard contains a rotary chamber filled with six types of Dust blades: green, cyan, red, dark blue, purple, and yellow.

When drawn, the blade telescopes to approximately double its stored length.

When Raven drew her sword on the train, a small burst of black-and-red energy flashed around the mouth of the scabbard as the seal was broken.

Trivia

 * Due to the blade's red coloration, Raven's Sword bears some resemblance to the swords wielded by some of Junior Xiong's Henchmen, as well as Adam Taurus' weapon, Wilt. The rotating chamber in the scabbard also demonstrates similarities to Weiss Schnee's Myrtenaster.
 * Due to the blade's full length when drawn, it would not be considered a katana, which has a shorter blade length. Japanese classification makes it an ōdachi.
