Naruto Uzumaki becomes the owner of a martial arts school named Ma Ming and starts teaching ninjutsu, leading humanity in its fight against the alien invasion.
A popular martial arts streamer: “I'm here to challenge your school. There are way too many people pretending to be masters these days.”
Ma Ming: “So you want to use martial arts to challenge my ninjutsu?”
Delivery guy: “You're saying I've learned the Flying Thunder God Technique?”
Ma Ming: “That's right. You'll be the top dog in the delivery business from now on.”
A big-shot businessman: “I've learned the Multi-Size Technique. This jutsu is really useful!”
Ma Ming: “Useful for what, exactly?”
Ma Ming: “Sasuke, I want you to be an instructor for my livestream course!”
Sasuke: “I'm busy fighting the Otsutsuki!”
Ma Ming: “That won't get in the way. I can use the System to ship some modern weapons to help you out.”
He establishes a ninja qualification exam and issues professional ninja certificates, organizes a world ninjutsu tournament, and teaches everyone ninjutsu. His fame spreads worldwide, and he becomes a master of martial arts and ninjutsu, leading his many disciples to repel the alien invaders.
