Conflagrant Arms

Bianco & Nero are the custom-made Energy Cannons wielded by Akira Izanagi in Endless Utopia Online.

Design
Both weapons have a transforming frame and share the overall appearance. The frames of the weapons take a pistol-like design, with a box-shaped barrel and an angular design. The grip of the cannons resemble the hilt of a longsword, albeit with a short-pull, pistol-style trigger and the pommel being replaced with a slam-pad for the "magazine" of the gun. Ring hammers have been installed into the guns, which are pushed in to activate the transformation to sword form.

While in sword form, the weapons deploy a dual-edged longsword blade from the barrel as the rest of the frame shifts to resemble a standard longsword. The triggers can allow Akira to release charged-up Chromatic Flames from the blade in a similar manner to the Getsuga Tensho technique employed by Ichigo Kurosaki or the Drive and Overdrive techniques the Rebellion can release after Dante charges the blade with energy.

Bianco has chrome plating, with white and red details, while Nero has dark chrome plating with black and blue details. As stated in Akira's profile, Bianco is wielded in the right hand, and Nero is wielded in the left hand. Both are dual-wielded together for maximum efficiency.

Trivia

 * Bianco means white in Italian, and Nero is black in Italian. Their names are the inspiration for their respective color scheme.
 * The transforming mechanism is inspired by the transforming weapons in the RWBY series.
