The instructor also would not know whether Seiya was already a multi ability user or what and just guessed that he was currently a solo ability user because the blades he controlled were not conjured out of thin air.
But how could that instructor know that the blade was indeed not made using a special energy but was created with another ability?
The products that were created by the Realism Art ability all felt and functioned almost the same as the real object, which was why, this ability was not only an all-rounded ability but also good to pretend to be another ability.
After the war and after six months of going around the world, Ainsley could already use the Realism Art without summoning her magic brush.
She just drew the desired object or creature in her mind and then the object would immediately appear, as if it was not created with special energy but a real object.
