The Defense Against the Dark Arts Professor Took Leave Again

After knocking "Kreigs" unconscious, McGonagall cast an Untransfiguration Spell on his face, but nothing changed.

"What—?!"

McGonagall's heart tightened. Had she struck the wrong person?

It seemed this Human Transfiguration incorporating Metamorphmagus traits was rather special and could not be reversed through ordinary Untransfiguration...

Manus understood. So that was why...

Could this version of Human Transfiguration really withstand the Thief's Downfall?

Gringotts' security was even more lax than he had imagined.

Manus extended his wand and tapped the man.

"Secret Revealing!"

A Transfiguration that Manus fully understood naturally held no secrets from him. The artificially altered face and body twisted, reverting to their original form.

McGonagall shot Manus a surprised look.

"Ordinarily, Untransfiguration is the most effective counterspell against the effects of Transfiguration... It seems this Transfiguration was specially designed to counter Untransfiguration, but appears to have overlooked other counterspells."

That was not actually how it worked...

From McGonagall's words, Manus could tell that she only had a vague understanding of how counterspells functioned.

Because counterspells in this world were not designed specifically for the magic itself, a single spell could have multiple effective counterspells. The more universal a counterspell was, the less targeted and effective it became.

However, it was important to note that this weaker effect was the counterspell's true effect. A powerful effect did not mean the counterspell itself was strong; it merely meant it had received a corresponding bonus.

The core of Untransfiguration was the intent to restore something to the form it had possessed before being artificially transformed, which was why it was especially effective against Transfiguration Spells.

When faced with this New Human Transfiguration, however, part of the Metamorphmagus principle had been incorporated into it. The target's transformation could therefore be considered, to some extent, innate, interfering with the core effect of Untransfiguration and
