Interactive Phasion

Based off the Phasion Technique taught to him by his sister, Saisha Korimachi, Ace took it a step further, after 2 years of in-depth study of Quantum Physics, Quantum Teleportation, his Phasion Technique, as well as Space-Time Ninjutsu.

By instantly sending half of his molecules between a random separate dimension and the real world, Ace can pass through and interact with objects, while the objects can't interact with him.

 * Due to this technique, he earned the moniker "Phasion Ace", and has since developed a plethora of assassination techniques designed to kill targets at a moments notice.
