Learning Magic at Hogwarts? My Ninjutsu Takes Them Out Instantly

Carl transmigrates into the world of Harry Potter and becomes a noble.

But then he awakens some kind of Strongest Naruto System.

Others cast spells with wands, but he... forms hand signs!

Others silently chant incantations, but he... forms hand signs with his mind!

Seven years fly by.

Voldemort returns.

Wait, what is that Almighty Push?!

Wait, what is that Planetary Devastation?!

Carl turns around.

"That's right, I'm the greatest master of ninja techniques in the Harry Potter world!"
