Even Mr. Miyagi from Karate Kid would be impressed by a seven-year-old girl named Mahiru from Japan. She puts every single ounce of energy she has into her karate, and as you can see in her eyes, she's pretty serious about it.

Everything you do in life is all about focus. And when you're seven-years-old, and the focus is uninterrupted by anything adults have to deal with, the results are pretty spectacular. Mahiru, a first grader, demonstrates the most intense and perfect karate moves you've probably ever seen. She demonstrates the Kanku Dai kata (form), a set of karate moves that will be sure to protect someone when necessary. Watching her will make you feel that a seven-year-old-girl can do some damage if she just puts her mind and body into it.

Just take a look at Mahiru.
