Demon Slayer: Upper 0 seems to be a waste

Butterflies are very beautiful.

And the same goes for the two sisters whose last name is Butterfly.

The older sister is beautiful, and so is the younger sister. To use Rinko's words, this is the dinner that Dakimaki would be willing to spend a month setting a trap to catch.

"Rinko—"

The childish voice drifted far away on the wind. The outsider was sure that the boy whose name was called must have heard her voice, but unfortunately the person who was called did not show up.

"Shinobu, it's too loud. People will notice."

"Sister, if we don't speak louder, how will he know we're looking for him? This mountain is so big, who knows where he's gone? It's rare that mommy made food for him, and it won't taste good if it gets cold.

For human children, the night is full of dangers, but even during the day, such a dense forest is full of dangers that are not easy to detect, wild boars, wild dogs, and maybe even bears. It is not surprising to see anything in such a big mountain.

"Be careful. If you fall anywhere, Rinko will have to rescue you first."

Kanae caught Shinobu who was almost tripping and smiled helplessly.

"No way! But why would he stay in a place like this where there are dangers everywhere? Daddy clearly said that it's okay to come home."

Shinobu took a deep breath to calm his frightened heart, his words revealing nervousness and irritability.

"So you know this place is full of danger, but you still want to come here?"

The voice came from behind, and the sudden noise nearly made Shinobu stumble again.

"Rinko! Don't suddenly appear behind people and speak suddenly!"

After realizing who the voice belonged to, Shinobu turned around and expressed his dissatisfaction to the boy who was tilting his head with a curious look on his face.

"I stood behind you and listened to you finish speaking before I spoke."

"Then you just came over suddenly! Next time, make a sound while you're walking towards me."

Rinkou's reactions are always slow, while Shinobu has always been straightforward. It's always lively when these two people get together. Kanae couldn't help but chuckle a few times, and started to persuade before things got even more lively.

"Okay, okay, Shinobu, Rinkou didn't mean it, and that's not what we're here to talk about, right?"

Kanae's advice always works well on Shinobu. She breathed a sigh of relief and handed over the food box she had been holding in her hand. Rinkou reached out to take the box and opened the lid after a glance from both of them. As the lid opened, the aroma of the food spread out completely. It had a similar taste to the small pastries that the male owner of the house had given him before, but this time it smelled sweeter.

"Is this for me?"

Lin Guang turned his eyes away from the bunny-shaped dessert and looked at the two sisters from the Butterfly family.

"Otherwise, did my sister and I run so deep into the mountains just to feed the wolves?"

Shinobu crossed his arms and pouted.

"Shinobu-chan."

"I'm not wrong."

Shinobu's tone was completely justified.

Although Kanae and Rinkou are older than her in terms of age, the only one she truly recognizes is her sister Kanae.

As for Rinkou, who looked slightly taller than her, he only looked slightly taller. In reality, his arms and legs weren't much bigger than hers. It was unclear where he got the strength to carry a grown-up like his father. His reaction was also quite slow.

"Thank Madame Butterfly for me. I loved it."

Lin Guang didn't care about Shinobu's words, his attention was almost entirely on the pastry.

Kanae caught Rinko's little thoughts, held Shinobu's hand with one hand, and held Rinko's hand with the other.

"Then let's find a place to rest. It's a good opportunity for Lin Guang to taste his mother's cooking. It would be a shame if it gets cold later."

The one who was more familiar with this place was naturally Lin Guang. The boy walked in front and brought them to an open area after many twists and turns. Further ahead was a clear lake. The sun shone on the water, and the water shimmered in the breeze. The surrounding grass also swayed in the wind. It was truly a beautiful scene.

While the two girls were enjoying the scenery, Lingguang stopped and stayed in the shadow in front of the open space, sitting under a tree to taste the meal. Although it was a little cold, he couldn't taste anything on his tongue when he put the food into his mouth. In fact, Lingguang was not sure whether it was delicious or not.

He used to feel sorry for not being able to taste, but Muzan also said that if he could taste, he might not be able to eat human-made food that tasted like garbage.

Good and bad are interdependent. Perhaps not being able to taste something is also a kind of preference. Lin Guang always thinks things through.

-

The boy was sitting under the tree. Kanae noticed that the box had already been repacked and placed aside, but the boy just sat there, looking almost like a different person from the energetic boy he usually was.

"Rinkou—won't you come play with us?"

Shinobu opened his mouth to call out, but Rinkou just shook his head and didn't even show any sign of getting up.

"It's really strange. He usually seems to have endless energy, but now he's so well behaved."

Shinobu put his hands on his hips and walked towards that side from the lakeside with an indignant look. Kanae looked at Rinkou who was sitting quietly, and followed him, but spoke first.

"Doesn't Rinkou like water?"

Kanae squatted down and brought her eyes level with Rinkou's. When she asked, she got a negative answer and the boy shook his head.

"Then why don't you come over?"

Shinobu asked condescendingly, his hands on his hips.

“Because we can’t get any sun.”

He pointed to the sky above the open field, invisible in the shadows. Unlike before, he could now coexist peacefully with the daylight, but that was all. If he stepped out of the darkness, the sun would instantly kill him. Lin Guang understood this better than anyone else.

"You don't look that weak."

"I think so too. But you'll die if you stay in the sun, that's what my father said."

Rinkou took Shinobu's comments and confused looks in stride.

"Are you not feeling well?"

Unlike Shinobu, Kanae asked more tactfully.

"Ah."

Lin Guang nodded this time.

----

Lin Guang is a very strange boy. He seems to have no home and has always lived alone in this dangerous mountain. He also seems to have no relatives, no one is by his side, and he only talks about a "father" that no one has ever seen.

"Is his name Rinkou... He's a poor kid."

The father said that he had seen Lingguang. The boy always played in the water alone by the river and sometimes went to catch fish in the river, but the boy only had two hands, so he could never catch any big fish.

The slender arms and legs, the body that could barely support the loose coat, the pale skin, the cold palms that touched when he put the pastries into his hands, every detail told the pharmacist that the boy was not in good health.

But this boy carried the unconscious boy down the mountain and sent him home late at night. When he woke up and heard about this, his face was filled with unconcealable surprise.

Obviously, this is irrational, but it is true. Perhaps someone else helped her that night, or perhaps Rinkou used some other method, but this cannot hide the fact that Rinkou has a greater power than that body shows.

That morning, before the sun rose, Rinkou left without saying goodbye. But he didn't just disappear like that. When Kanae and Shinobu went up the mountain to pick herbs for their father, they met the boy. At that time, he was sitting on a tree, looking at the unripe fruits, as if hesitating whether to pick them and taste them.

Seeing this, Shinobu loudly advised him not to do that. Lingguang hesitated for a while, and finally accepted her advice and took the initiative to come down to accompany them to look for herbs in the mountains.

That's how they met. After spending time together and chatting along the way, they became friends. The friendship between children is always pure and straightforward.

They would come to play with Lin Guang, and Lin Guang would come over when he heard the call. The adults always said that the mountains were dangerous, but they had never encountered any danger. The most dangerous situation they encountered was that the branch they climbed up broke, and they suffered a disaster.

His father said that Rinkou looked very weak, and Kanae shared the same opinion with her father. However, surprisingly, this boy had abundant energy that was completely different from his weak appearance.

However, Kanae has almost never seen what Rinkou eats. He seems to not need to eat anything, nor does he seem to need to sleep to maintain plenty of energy, which is something that adults find difficult to do.

There are many inexplicable things about Lin Guang, and these doubts eventually converge into a lively, cheerful, friendly and gentle boy.

Everyone has their own secrets, maybe Rinko also has her own secrets. Kanae has never thought of revealing the secret that Rinko has never mentioned. They are friends, Rinko has never thought of doing anything bad to them, and they also like this somewhat strange new friend living in the mountains, which is good.

That's what Kanae thought.

If the price of secrecy were not so starkly laid out before us, perhaps things would remain the same.

Lin Guang had never been so weak in front of any of them. The boy knelt heavily on the ground. He was listening to them talking about the things in the town the previous second, but the next second he suddenly knelt on the ground with his hands covering his abdomen, cold sweat coming out of his forehead and dripping along the contours of his cheeks.

No matter how Shinobu called out, the boy seemed to be deaf to his calls and simply curled up, a posture he used to try to relieve the pain. The reason was unclear, but the conclusion was that Rinkou was in pain.

"Rinko! Come back with us! Father will definitely find a way!"

Shinobu made a decision. She immediately wanted to pull up the boy who was kneeling on the ground, but Rinkou was taller than her after all, and under the special circumstances, he could not cooperate with her movements. No matter how she dragged him, Rinkou just curled up on the ground.

Kanae knew very well that the two of them would not be able to bring Rinkou home in his current state, not to mention that Rinkou said that he couldn't bask in the sun. Although she didn't know why, Rinkou never lied and would never make such a joke.

"Shinobu, I'll stay here and watch him. You go find your father. Can you do that?"

"it is good!"

There are many questions and confusions, but what Kanae can do and must do at this moment is to help her friends.

The forest is very dangerous. Even if they are lucky enough to never encounter wild animals, she doesn't dare to take the risk and leave the immobile Rinko and Shinobu here. She can't.

"Rinkou, hold on a little longer. Shinobu will be back soon. Everything will be fine once father comes. He will definitely be able to heal you."
