Everyone was shocked that Tatsuya defeated Hanzou so quickly. It is revealed that he used physical abilities from his Ninjutsu training to get behind Hanzou and used a basic oscillation type spell "Compound Waves" that causes hallucinogenic effect, which is using Silver Horn CAD's Loop Casting feature and a complex multivariable processing in its execution, to knock Hanzou down. He concluded that the school's entrance practical exam can't evaluate Tatsuya's true ability properly because multivariable isn't one of its grading criteria.
