Hellsong

Introduction
Hellsong is one of the legendary Shi no Uta Swords, a grade of sword that is only second to Saijo O Wazamono blades. Hellsong is the master sword of the Shi no Uta Flame Series and like all other swords in the Shi no Uta grade, it is indestructible and utterly legendary.

Powers
Like all of the Shi no Uta swords, this blade is a two sided claymore and is indestructible. However, this blade is unique from the other Shi no Uta swords, just like all Shi no Uta swords are unique. This sword, just like the other swords in the flame series can generate heat, but it is still special from the others. One of the things it will do is when it's cold outside, the sword will warm up so the user won't freeze. Another thing it will do is that when the user gets angry, the blade will set itself on fire, and the only limit to its fire is the limit of the user's anger. Along with that, because this sword holds the aura of hell, the sword seems to bring itself to devil fruit users, but it won't always happen, as seen in exactly one case.

Appearance
Hellsong is a one and a half handled claymore with a somewhat heavy blade that takes some getting used to. It has a long meteor steel blade with a golden strip with poneglyphs on it running down the middle. The blade itself has sort of a reddish glow that brightens and dims periodically. The hilt is curved at the ends and the whole thing is covered with red dragon scales. The handle is a heavy titanium comet steel alloy covered by black leather that makes the blade swing better. Finally, the cap of the sword is a small hollow holding pyramid that holds a spherical amethyst.

History
In the past this sword has only been owned by devil fruit users, as the power of hell attracts itself to the power of the devil. Each of these devil fruit users were all ittoryu swordsmen who only used one sword and used it right. There have been a total of 27 owners of this sword, and only the most recent user is not a devil fruit user.
