Allegro (Allegro) Allegro is a child-like robot, who is a genious in constructing Dimensional Areas. Surprisingly, it is revealed that Allegro was made by a navi who had been presumed dead: Forte! Or actually, Forte in Shuryou's old robotic body. Forte comments that Allegro is like his little brother....which is not exactly what he planned. Allegro's low level of actual intelligence convinces Forte that he is of no use to him, and simply an annoyance. And so, Forte kills him by his own hand.

Allegro is annoying, and ugly to look at, but the poor thing still didn't deserve to die. n.n;
