Luke Florence is a renowned and skilled knight within the empire. However, disillusioned by the exploitation of his abilities in the power struggles of nobles and aristocrats, contrary to his belief in wielding a sword for the weak, he relinquishes all his wealth and honor.

He longed to start a new life in a place where no one knew him. Thus, he ended up here, at the western edge of the Hesperion Kingdom, in Ezbon.

It was truly a noble gesture when he volunteered for the professor position upon hearing that the children would graduate from the academy without ever holding a sword due to the lack of swordsmanship instructors.

In the novel, Luke immediately recognized Kamian as a demon, yet he imparted generous teachings without prejudice. Even after Kamian turned dark and massacred the people of Ezbon's village, Luke, who cherished him as a beloved disciple, could not raise his sword against him. On the other hand, Kamian effortlessly turned thousands of humans into piles of flesh within half a day.

I silently gazed at Kamian sitting beside me. When Kamian sensed my gaze, he turned and said, "What?" However, I had nothing particular to say and merely stroked his cheek.

"Live kindly, my friend."

Kamian frowned and brushed my hand away abruptly.

At that moment, a white-haired, tidy-haired theology professor entered the classroom. The professor distributed transparent glass bottles adorned with crosses and rough-edged stones on the desks of the undergraduate students.

"These holy water and relics have been most useful when facing demons throughout our long history. When we touch these holy water and relics, we feel nothing, just like touching ordinary water and stones by the roadside. But demons are different."

This story has been taken without authorization. Report any sightings.

I glanced briefly at Kamian. He played with the relic, tossing it back and forth, with an unimpressed expression on his face. "Um, Professor, don't demons feel the same?"

"When demons touch the relics, white smoke spews out, their skin melts away, and they experience excruciating pain."

I took hold of Kamian's hand and pulled it towards me. After removing the relic he was holding, I gently stroked his palm. "Um, Professor, he seems perfectly fine. I even ran my hand over Kamian's palm, feeling the familiar texture of his smooth and solid skin, as always.

Kamian, with his other hand free, rested his chin on it and stared at me intently. In a soft whisper, I spoke to the quiet Kamian.

"It seems to be a counterfeit."

"Really?"

At that moment, the professor showed us something resembling bat wings.

"This is the skin of a lesser demon. Now, when you bring the relic close to it, you'll see. Watch as the skin melts like a liquid."

Kamian raised an eyebrow at me. I added another remark to Kamian.

"Professor, your arrogance seems quite genuine."

As if he had heard my whisper, the professor approached our desks.

"Kamian, would you like to try touching the relic?"

Kamian casually picked up the relic with a nonchalant expression and pressed it against the skin. Instantly, the skin emitted white smoke and melted away.

"Any other undergraduate students who would like to try?"

Hands shot up all around the room, each student eager to participate. I stared at Kamian with wide eyes.

"What are you? What's happening to you?"

"It seems I'm immune."

"Why, even though you're a demon?"
