Stormhowl

Stormhowl ( Gouran?) is the name of a legendary sword from Tales of Berseria. It is currently in the hands of Rokurou Rangetsu, a powerful warrior of the Rangetsu family. He is one of the few characters who know how to use the sword to its full potential and claims it as a treasure or relic of sorts. The sword has even been referred to as Sword of Life (命の太刀 Inochi no Tachi?, can be referred as "Katana of Life"). It is claimed to have the power to take down the top exorcists of The Abbey.

Rokurou claims it as his "partner". However, later in the story, it was discovered the Stormhowl carried by Rokurou was an "imitation" while Shigure Rangetsu, his older brother, carried the real one. Rokurou eventually kills Shigure and takes Stormhowl for himself.
