Hogwarts: You Cleared Out the Forbidden Forest?

[Muscle-Bound Hero + Invincible Protagonist + System + Hufflepuff + Laugh-Out-Loud Comedy]

Dumbledore: “Mr. Walker, I've told you many times: ‘Expelliarmus’ is supposed to make your opponent drop their wand, not break their arm!”

Voldemort: “That day, I cast Avada Kedavra at him, but he countered with a judo throw. It was the darkest moment of my life.”

Hermione: “It may not be scientific, but Lynn's muscles really can deflect spells...”

Reborn in 1991, Lynn Walker transmigrates to Hogwarts with the [Titan Body System].

In this world of people waving little sticks around, he believes the truth is only within arm's reach, and magical power is measured by muscle size!

A wand? Isn't that just a limiter?

A broomstick? Too slow. I can jump higher with a running start!

Fluffy? That's my petting target!

While other wizards are still working hard to perfect their spell pronunciation, Lynn is already carrying the golden dumbbells he had forged at Gringotts and starting his daily ten-kilometer weighted run.

Lynn: “Wizards are terribly out of shape. I just want to get everyone exercising together, and, while we're at it... ascend through physical strength.”
