Of course, this isn't an illusion art technique, but an illusion art technique boosted by Qi!
Using the Qi of an elite fighter as a basis, serving as the source of power for the illusion art technique. Naturally, this brings about a power that is beyond imagination, capable of directly interfering with the physical reality.
Because Qi exists as an entity, contrary to being merely spiritual. Boxing willpower can solidify Qi into a technique with immense power, the same applies to illusion art. The illusion that Casio crafts shouldn't be deemed a mental illusion technique, but rather a physical illusion technique - a direct attack from reality against the caught enemy.
This kind of illusion art technique, others can't and won't be able to learn.
Essentially, the illusion technique is simply a vent, similar to employing a stick to leverage Casio's colossal Qi.
Thus allowing the Qi to manifest its power without going through the body.
