Touya mainly uses the slender stiletto that mysteriously emerges from the palm of his hand. In the beginning he has no idea how he can call forth such a weapon, as it is not natural. Nevertheless, he uses it to carry out Kagami's orders, and to protect himself. At first he tries to fight Ceres with it, but when he finally betrays Mikage International he uses it to kill off their petty suits. The dagger can also cause small explosions and create a shield. The small explosion ability helps him break through doors, especially when he escapes from the Mikage Int'l building. When he gives his dagger to Aya, it creates a barrier to protect her when Shiso gets too close.

Touya also uses a regular old pistol when he breaks into Mikage Int'l to save Shouta and Chidori. It's nothing too fancy, but it gets the job done and that's all that matters.
