The decision to leave the Kamado family had been made a long time ago. The conditions to complete this "instance" could not be fulfilled within the Kamado household, so Li Mo could only do his best to guess the exit conditions.

But guessing was just a possibility. In the end, it was up to the system to decide. It was like being given a task by a superior without clear instructions—you had to figure it out yourself.

Figure it out? Screw that!

One day, I'll smash this system to pieces!

On the first night after leaving the Kamado family, Li Mo checked his belongings. First, there were the things he brought with him: Tanjuro's axe and his phone, which he couldn't part with. The phone was the only piece of modern technology he had, a symbol of the modern world. It held sentimental value.

Next, there were the items in his bag, including something given to him by Tanjuro.

"Earrings? Sun-themed earrings?"

The sun-themed earrings had been passed down through generations of the Kamado family. They were an accessory from hundreds of years ago. There should only be one pair, so why did he have another?

Li Mo picked up the earrings. They looked old, as if they had endured the passage of time.

"Are these replacements? That must be it." He recalled that when he left, Tanjuro was still wearing his earrings.

The pair he held must be a spare. That made sense. After all, could earrings gifted by Yoriichi Tsugikuni really last hundreds of years without damage? The Kamado family must have replaced them over time.

Having figured this out, Li Mo continued to check his belongings. Clothes, food, money—everything was there. Surprisingly, he had a considerable amount of money. Thinking of Kie's smile and Tanjuro's instructions, he shook his head.

After finishing his inventory, he sat by the campfire and slowly closed his eyes.

The boy named Li Mo had almost fled the Kamado household. It was too warm there, filled with everything a family should have. He was afraid that if he didn't leave soon, he would never want to leave.

...

...

Demons were relatively rare in this era. Otherwise, the Demon Slayer Corps wouldn't be an unofficial organization unrecognized by the government. Because they were rare, most ordinary people believed demons were just legends.

Many people would never encounter such creatures in their lifetime. Those who did usually ended up as dinner for the demons. Only a few were saved by "demon slayers" and survived.

Of course, there were also a very small number of people who were exceptionally gifted and could kill demons without a Nichirin Blade.

A month after leaving the Kamado family, Li Mo encountered a demon.

His first encounter was in a small temple in the wilderness. He had planned to rest there, but upon entering, he saw the demon eating someone. He had no choice but to fight for his life.

—By using an axe to chop off the demon's head.

"Not having a Nichirin Blade is such a hassle."

Looking at the demon he had dismembered into several pieces with his axe, Li Mo sighed. The faint light of dawn was beginning to appear in the east. The rising sun would deliver the final blow to the demon.

A demon's regenerative abilities were limited, at least for those who hadn't eaten many humans. Even if its head was severed, it could still control its body, and even grow new hands from its head. But it didn't matter—Li Mo smashed its head and chopped its body into pieces. After a few struggles, the demon's strength waned, and Li Mo eventually knocked it unconscious.

Then, he waited for sunrise.

When the sun illuminated the earth, the creatures of the night turned into a wisp of smoke and vanished into ash.

This demon probably hadn't eaten many humans. Against Li Mo, who had mastered "Softening" and breathing techniques, it stood no chance. If only he had a Nichirin Blade, he could have decapitated it and ended the fight immediately. Instead, he had to wait until dawn.

"Speaking of which, where have I ended up?"

The battle with the demon had dragged on for most of the night. Now that everything was over, Li Mo looked around and realized he was in an unfamiliar place. He was at the edge of a forest, and the morning sun felt particularly comforting on his skin.

"I want to sleep."

He had originally planned to sleep in a rundown temple on the mountain but ended up encountering a demon eating someone. The struggle had lasted until now, mainly because the demon was good at running away. After Li Mo decapitated it the first time, it grabbed its head and fled.

He had chased it all the way here and was now exhausted.

Basking in the sunlight, Li Mo first checked his belongings. Everything was still there, but his rations were almost gone.

Then he headed toward the direction where he had heard a rooster crowing. If there was a rooster, there were likely people nearby. He also spotted a path—a human-made path, judging by the lack of weeds. It was probably frequently used.

"First, I'll see if I can buy some rations. Then, I'll ask if I can stay the night. Finally, I'll find out where I am."

"I think I took a wrong turn."

It had been a month since he left the Kamado family. This was the first time he had encountered a demon. The rest of the time, he had been interacting with people. He had gained some experience traveling and knew that staying in larger towns was better because they had proper lodging and food. If he came across a village, he had to be cautious—what if the villagers tried to rob him? Sleeping in the wilderness was risky because of wild animals.

—Oh, and now he had to be careful not to let demons have a free meal while he slept.

The world had its bad side, but it also had its good side. On his way to the village, Li Mo met a man who seemed to be a local villager.

"Do you need help?"

Before Li Mo could say anything, the man asked if he needed assistance. Though puzzled, Li Mo exchanged a few words with him and decided to rest at his house.

From the man, Li Mo sensed a personality similar to the Kamado family.

"So you're heading to Mount Sagiri? You've taken a detour. But it's understandable, given that you were chased by a wild animal."

During their conversation, Li Mo told the man that he had gotten lost after being chased by a wild animal.

Calling a demon a "man-eating beast" was an insult to actual beasts. Even tigers wouldn't eat their own kind!

"By the way, there have been many disappearances in the mountains recently. We suspect it's due to wild animals. Have you seen what the beast looks like?"

"I fought with it all night and chased it for a long distance. I don't think it's from around here," Li Mo said.

Last night had been a game of chase. But this time, Li Mo wasn't the one being chased—he was the one doing the chasing. After being hacked a few times by Li Mo, the demon got scared. Maybe it was already full, or maybe it was because Li Mo threatened to scatter its ashes when the sun rose.

In the end, the demon fled, and Li Mo chased it all the way until it turned to ash.

It had been almost half a year since Li Mo arrived in the Demon Slayer world, and this was the first time he had encountered a demon. And the demon was so weak that he got carried away.

"Have you found the bodies of the missing people?" Li Mo asked.

"No, we haven't found any bodies. That's why I asked you that question earlier."

"I see."

When wild animals attack humans, they usually leave behind remains. But with demons, it's different. Intelligent demons, if they choose to, can devour humans without leaving a trace.

As their conversation continued, Li Mo learned that the man was a doctor who had gone into the mountains to gather herbs. He had run into Li Mo on the way. The man was kind-hearted, much like the Kamado family.

That was Li Mo's assessment.

Following the man, who appeared to be in his twenties or thirties, back to his house, Li Mo met his daughter.

"Are you my father's guest? Do you need any help? Oh, has my father not introduced himself yet? Well, that's just like him. Let me introduce myself—I'm Kanae Kocho, my father's daughter. What's your name?"

Looking at the familiar-looking girl and hearing her name, Li Mo replied, "Li Mo."
