Using the same process that used to merge the excailbur fragments in volume 3, kiba's demon swords are merged into a single black and red blade that loks similar to his sword of betrayer. Name either

Dark fang: after the character he plays on oppai dragon

or

Chaos Edge: after his dead rival, Siegfried aka "chaos edge" sieg.

what do you guys think?
