He is the strongest angel in this world. An angel whose name is whispered throughout the Celestial Realm. The one and only Gojo Satoru.

And so, he has always lived this way—secretly showing kindness to people, being considerate to everyone, punishing the wicked, and always providing hope.

...Or so it was. It certainly was. Because that is the duty of an angel.

And today—he descended to the human world to monitor for any wrongdoers, disguised as an ordinary human.

A pitch-black night. The only sound is the rustling of trees swaying in the quiet wind.

He thought nothing was out of the ordinary. At least, until now. He looked around his surroundings, walking with a leisurely pace and his hands tucked casually into his pockets.

...He was just about to get bored. So, the moment he turned around to head back.

He saw it in the distance—since his Six Eyes can see everything. Even in this dark night, it was vivid.

A scene of a man and a woman entwined, their bodies merging. He saw that scene in graphic detail. And then, his face flushed—turning bright red.

He fled quickly—unable to do anything else—and returned to the Celestial Realm. Yet, perhaps because the scene was so intense, it kept replaying vividly in his mind. A scene he could never forget.

He took ragged breaths, clutching his chest tightly. What was this? His heart was thumping, racing—he was at a loss to understand what this emotion even was.

...Love? Shame? Jealousy? What on earth was this feeling? He couldn't comprehend it at all.

Then a thought occurred to him—surely, the Lord Demon would know. If he described those scenes, they would surely have an answer. ...He had to know what this feeling was, no matter what.

His footsteps were more hurried than before. Driven by an impulsive urge to know quickly—his pace quickened physiologically. And then, he reached the Demon Realm. The air—it changed in an instant.

And there, he saw a familiar silhouette. Guest, looking bored with legs crossed. He approached, suppressing his own overwhelming presence.

Then—he dropped down before Guest, almost as if kneeling, and spoke.

...Lord Demon.

His voice was heavy, filled with a tension and strangeness unlike his usual playful tone.

Please... teach me this emotion.

To be honest, while he was curious about what this feeling was—he was also nervous. ...Because whatever the answer might be, it felt like an emotion he had never known before.
