In the world of Type-Moon, it all begins with becoming Morgan's husband!

"From this moment on, you and I are master and disciple."

Upon hearing this, a look of surprise appeared in Minamoto no Yorimitsu's purple eyes.

"Thank you for your permission, Master."

"I will remember this kindness forever."

"That's not necessary."

Ian stopped Minamoto no Yorimitsu from expressing his gratitude.

Whether what I teach you will be helpful to you is still up for discussion.

"But Master—"

Minamoto no Yorimitsu looked at the man before him with deep gratitude.

"It is a great honor for me to have your approval."

"This at least means that my efforts were not in vain!"

"……maybe."

Ian glanced out the window, his expression growing more somber.

"Yes, as agreed—"

"Starting tonight, I will teach you the art of slaying demons."

"Lai Guang, this is a matter of life and death, you cannot be careless in the slightest, understand?"

"Yes, I understand!"

Minamoto no Yorimitsu responded to Ian with utmost seriousness.

"I will remember every step!"

"Okay, I feel much more at ease now."

"Come with me."

You took the marked Minamoto no Yorimitsu out of the house.

You and she arrived at the village road.

[Your innate anxieties have been replaced by the guidance of an Onmyoji: You've decided to reveal the true nature of exorcism to Minamoto no Yorimitsu tonight.]

Of course, you no longer intend for her to give up this idea, but rather to make her aware of the potential dangers as early as possible.

You swore you would keep her safe.

"Yakou."

"Yes, Master."

"Since you've decided to embark on the path of exorcising demons—"

Ian looked at his voluptuous apprentice beside him.

"Shouldn't you have known about this beforehand?"

“Yes.” Minamoto no Yorimitsu nodded. “I’m not the kind of person who makes decisions on a whim.”

"Alright, tell me your understanding of killing demons."

Ian looked at the other person.

I'd like to know your opinion on it.

"it is good."

Minamoto no Yorimitsu was not afraid to reveal his thoughts to Ian.

"There are many evil and alluring things in the world. When thoughts run deep, they will take real form and appear in the mortal world."

"This is often accompanied by many dangers, so it must be dealt with as soon as it appears to prevent the growth of sins and the causing of irreparable damage."

"This action aligns with my desire to gain fame and revive the Genji clan, so killing demons is beneficial to me."

The underlying logic is consistent and correct.

Minamoto no Yorimitsu was convinced that this kind of thinking would make him incredibly determined.

but--

After listening to her words, Ian did not give her an approving look.

Instead, he fell silent.

After a long while, the great Onmyoji finally spoke again:

"So, Raikou, you're just someone who can see and exorcise ghosts, right?"

"Eh?"

Although he found Ian's question somewhat strange, Minamoto no Yorimitsu nodded very seriously.

"Yes, Master."

"Only by seeing the ghost can you kill it."

Isn't this perfectly normal?

"Yes, you are right."

Ian's gaze fell on Minamoto no Yorimitsu.

“But Lai Guang, you missed the last and most important step.”

"The final and most important step?"

Minamoto no Yorimitsu blinked, clearly not understanding what this meant.

However, Ian didn't mince words and explained directly.

"Yes."

"That is the 'Demon Slayer'."

"It's good that you know ghosts are born from the deep-seated evil thoughts."

"But you also overlooked the meaning of the concept of 'birth'—the ghost is the product, while thought is the source."

"Ghosts are a product, while thoughts are the source?"

Mitsuru Minamoto began to think seriously about what Ian had said.

Soon, she had an idea.

"Master, do you mean that simply killing ghosts is not enough, we need to figure out why ghosts appear in the first place?"

Hearing the answer he wanted, Ian smiled with satisfaction.

"Lai Guang, you are indeed very clever."

"Yes, killing the demon is just the beginning. The real issue to consider is how to prevent the demon from continuing to haunt this world."

"With a hundred ghosts and a thousand forms, finding the matching resentment among them is often the most troublesome thing for Onmyoji."

"A slight mistake could cost you your life."

Your words caused Minamoto no Yorimitsu to fall into deep thought.

She now has a deeper understanding of your previous warnings.

The task of slaying demons is like a tangled knot; if the scissors are wielded incorrectly, the consequence will be suffocation and death.

You realize that this might shake her resolve.

But the result was not so.

"understood."

Minamoto no Yorimitsu gripped the blade of the sword at his waist.

"So, Master, are you now going to show me how to do it?"

Ian was somewhat surprised that Minamoto no Yorimitsu adjusted his speed.

But at the same time, I feel gratified about this—a rare and precious mindset.

"Well, that's about it."

"I think I said that before you leave together, you should do something more for this village."

"Yes, you said that."

"So--"

Ian stared directly at the waxing and waning of the moon.

"It's about time."

No sooner had the Great Onmyoji finished speaking than a voice came from afar.

It was a clear and pitiful cry from a child.

In the stillness of the night, it was so clearly audible that it sent chills down one's spine.

"Whose child is crying?" Minamoto no Yorimitsu couldn't help but ask.

But as soon as she finished speaking, she noticed Ian's expression.

His expression was solemn and serious, completely unlike what one would expect when hearing a child cry.

In less than a second, Minamoto no Yorimitsu realized—this was the voice Ian wanted him to hear.

She leaned close to his ear and whispered:

"Master, have we encountered a ghost?"

“Hmm.” Ian nodded.

"That's why I've been staying here a lot lately."

"Because the Kawakita is nearby, if we don't deal with him, he will bring disaster to this village."

"Kawachiko?"
