My first home in a long time feels very nostalgic and Yuto feels horrible.

Because he had told him that he would return on this day, or that the front door was not locked, and Yuto went inside intact. I don't know if it's inadvertent, but if there's anyone in there, the Dondo family has always felt like this.

Sometimes there is nothing to steal from this poor dojo, but the only inhabitant is a man, and above all the master of the Don Du family does not procrastinate when robbing.

"Grandpa, I'm home! Grandpa!"

(Is that it? You haven't heard back)

There's no way he's just not here this time.

When I contacted her, I was worried that she might reluctant to consult herself, as Hakazo was a pain in the ass. But unexpectedly, he said, "Just in time, I need to talk to you about something important."

At this time, Yuto hung up intuitively wondering if Kazuo was going to discuss the same contents as himself.

(The Julians who have assaulted the Four Heavens Temple family. Those people are likely to have connections to the demonic world. If that's the case, Don Du shouldn't have to shut up either)

Yumen turned on the lights in the hallway and opened the livingroom, where he spread several kinds of magazines over the tatami, with a difficult look and a entanglement sitting with his arms together.

"Oh, my God, you're here. Answer me, Grandpa... what are you doing?

Yuto shifts his gaze to a group of magazines whose entanglements are roaring and staring... his head is like "??" to be filled with

"What? What is this? Ten honeymoon destinations?? Popular Ceremony Program??????

"... yeah? Hey, Yuto! You're back! If you're back, why don't you call me!

The ugly and extremely hasty entanglement puts the magazine together and hides it behind.

"I was talking to you. Rather than...... what were you looking at?

"Nothing! It's nothing! I haven't seen anything!

……

I wanted to penetrate into whether that was a human expression and attitude that was nothing, but it's always the case that when I seriously try to tangle with what I'm entangled in, I don't get the translation.

When I was about to tell an important story as a Don Du family, Yuto decided to go through because I wanted to avoid getting off topic.

"Ah, Grandpa, it's quick, but I need to talk to you."

"Oh, oh, um! Then bring me some tea."

"Okay. Tea leaves are the usual place?

"Bye!

When Yuto leaves his luggage and goes to the kitchen, he hears a desperate attempt to hide the magazine from behind him. Yuto boiled the tea with his face.

As soon as I arranged the tea on the table, Yuto cut it out.

"Grandpa, we're not talking about anyone else who attacked the Four Heavens Temple family."

The entanglement sips tea.

"Oh, those powerful people? What happened to those guys?

"Huh!? Grandpa, didn't you notice?

"What is it? What happened to those guys? No way...... actually a woman or something!?

"There's no reason! They have a verse about the demon kingdom! Not only that, but there's a chance that he's still connected to the demon world, or the demon gods."

"Mm, is that true? Blessings."

When I hear the word "demon world," my eyes also sharpen when I hear that old hachachacha man's entanglement.

That's natural. It's about the significance of Don Du's existence.

Yuto has a headache that you were overwhelming those people with nothing to think about.

"Hmm... I don't have any proof. But I'm pretty much sure. Those guys were using the half-descendant technique that the humans attached to the demon side of the demon kingdom were good at. Besides, I even had demonization in my hand. I mean, those guys are in contact with someone in the demon world on a different route than Demon Cave. If so, it is an abominable problem for Don Du, who has protected the Devil's Cave. We have to identify those guys' tissues immediately and crush every route!

"Well, calm down, Yuto. Sure, that's very problematic. But I don't have much information. Perhaps they are not free to travel to and from the demonic world like the Devil's Cave. If so, by now, it's not weird what monsters are coming from the demonic world. If that were the case, Liaochi would have noticed right away."

"But...!

"I know. I don't know what method it is, but if it means I'm in regular contact with someone in the demonic world, I can't keep it that way. But when you do it, do it all. There must be no retrieval. Then repeat the same thing"

The expression disappears in the entanglement, and I feel a quiet, but cold, unspeakable qi. It's like making people think that those who get in the way will eliminate even the innocent.

But Yuto knows.

This is Don Du.

For a thousand years, we have been slaughtering or sealing demons, demons, and humans who have defended the demonic cave and sought to engage in the demonic world. That is the super sealed property that Don Du handles.

What is more, the reverse is true.

Don Du has traveled between this world and the demonic world. Don Du has suppressed all those who seek to come from the demonic side to this world.

All this is the role of Don Du decided by the first generation of the Don Du family.

Yuto never wondered why Don Du had to carry this serious and difficult role. Instead, I was proud.

Yu Man respected the first generation and, in a tangible way, "loved it".

Because he's a great ancestor, because there is.

But the real reason is because the first generation was taught by Takezo why he was determined to be the barrier of the present world.

That's what Yuto was told by the entanglement when he was a young man, practicing harsh training deep in the woods in the mountain hem of Fuji.
