Psycho-Blade was a very simple Psionic Skill. It could be categorized as the simplest Psionic Skill out there.
The user could use their imagination to summon their preferred weapon.
Mater had analyzed Selina's Blade Core from top to bottom and learned how it operated. He taught her a different way to use this core.
Instead of imagination, Mater taught Selina to use her heart to manipulate it. Chaos was close to one's emotions and using the heart instead of the mind was the superior tactic.
This method, however, prevented Selina from creating her preferred weapon. Instead, she had to use whatever it materialized for her.
Mater called this technique Chaos-Blade.
Selina clenched the practice core. Chaos wrapped around the metal rod and penetrated inside its components.
Energy shot out from within the rod and formed a dark sinister blade. That blade split and created four other blades, each with its own uniqueness.
