While Yuri writes and draws, the boy continues to walk upwards alone.

As he walked more and more, the boy learned more about the general shape of the building. This museum exhibits works of art created by mankind from ancient times to the present day, not a cylindrical building as the teenager first saw, but a building that resembles an ashtray. He found that the building was designed as a ring from the top of the third floor, and in the center of the circle was a tall stone monument made of obsidian.

"What a strange design............," said the boy who had climbed to the top floor, looking at the obsidian tablet that was just level with the top.

He looked at the stele quietly, and his originally unimpressed mood began to become a little solemn and heavy. From this tall stone monument, he seems to feel the weight of human history, and the stone monument itself seems to represent a kind of tribute to human culture.

The production of art is accidental and inevitable. But whether by chance or necessity, its generation is inseparable from human beings. Art can only be called art if human beings feel the beauty in it. And in this era when all mankind is going extinct, can these artworks displayed in this museum really be called art? The boy suddenly felt that the huge stone monument in the center of the circle must have been built to commemorate the dying human art! That's why he feels so solemn............

While the boy was looking at the obsidian stele, the two girls sitting at the bottom of the stele were still discussing what they had seen and heard in the museum.

"Now, you ...... I'm wondering if what we see and feel in the paintings is really what people used to feel? Senhe sat on a bench for tourists to rest, looking at the stone tablet in front of him and said.

"How so? …… I guess that's what those paintings are trying to convey...... Even if we don't, don't we understand a lot of things? Yuri said as she carefully sketched the figure on the paper.

"Yes...... But a long time ago...... If the mood of people who are different in clothes and food can be shared with us now...... This must be a very remarkable thing! Qianhu sighed.

After a few more minutes, Yuri, who was sitting next to Chito and painting, raised her head as if she had finished the last stroke.

"That's it! ............'re done," she said, looking at the painting with a satisfied expression.

"What were you drawing?" Qianhu asked curiously.

"What the hell is Sa~~~? …… It's the mood! Mood! Yuri didn't answer directly, but bought a pass.

"Anyway, you're hungry or something, right?" Senhe said, looking at his companion's paintings.

"Why do you know?!" Yuri exclaimed in surprise.

"Because isn't that all you have in mind?"

"Hmm.................." Yuri nodded embarrassedly.

The blonde girl looked at the painting in her hand and then at the petroglyphs on the wall, and suddenly had an idea.

"Na! If we have a chance, we might as well put this picture on the wall! ”

"Huh? Do you want to doodle this? Qianhu said with a surprised face.

"But you see, maybe this is the last painting of a human being, isn't it? I guess if it is pasted on the edge of the first painting of human beings, it can be regarded as having a beginning and an end! Yuri said, pointing to the petroglyphs.

"Well.................. That's what you say............" Chido nodded in agreement with Yuri's explanation after listening to her explanation.

The two of them pasted the painting next to the explanation of the petroglyph and went to meet the boy..................

"Huh~~ It turns out that the content of Yuli's painting is like this!" The boy said, looking at the painting on the wall.

What appeared in front of him was a painting sketched with a black pen, which depicted Chino, Yuri, and the boy himself. Because Yuri drew the characteristics of the three of them very carefully, so the boy could easily distinguish them, only to see Chito and the boy standing on both sides and Yuri in the middle holding a fish in her hand, and the faces of the three were filled with happy smiles, and if you looked closely, you could see Nuko coiled around Yuri's neck!

"How? Floating wave sauce. Yuri asked the boy what he thought.

"It feels pretty good! This picture ............," the boy said with a smile.

"Really?"

"Hmmm! I can feel a warm feeling of home from this painting! The boy complimented.

"Hey, hey~~" Yuri scratched her cheek after hearing this.

"More importantly............"

"More importantly......?"

"I can feel Yuri's dedication to food, I think you must be hungry when you draw this!" The boy laughed.

"Sure enough, I'm hungry or something!" Qianhu said emphatically on the side.

"Because I'm already hungry!" Yuri honestly admits as always.

"It's time to eat!" The boy looked at the 7:19 p.m. on his watch.

"Really?" Yuri called out in surprise.

"Hmm!" The boy nodded.

"Great!" The blonde girl raised her hands in the air and cheered.

“nu？ …… Where is this? At this time, Nuko, who was sleeping in the boy's backpack, asked as if she had been woken up by Yuri.

"Ahh Nuko............ "Yuri happily ran over and held Nuko in her arms and stroked it continuously.

“…… nuyi~~~”

"This is a place called a museum~~nuko." Yuri said as she stroked Nuko.

“nu？ …… What is a museum? ”

"Museum............ It's ............," Yuri introduced to Nuko, using what she had heard from the boy.

"Well! So be it! I'm going to convert the energy from the sculptures on the first floor, and it's okay if you want to keep strolling......" the boy said to the two girls.

“………… Never mind! I'll just go with the floating waves! Yuri, what about you? ”

"Of course, I'm going to dinner with Fukiba-chan!" Yuri said without hesitation.

“………… What you can't eat is worthless............" Nuko called.

"Looks like Nuko has been completely ruined by Yuri!" Chiho listened to Nuko's words and said speechlessly.

"Well! That's not bad, is it? In this world, instead of caring about art that cannot sustain one's own life, it is better to pursue the food necessary for life, and life is the greatest art! The boy said with a smile.

"I feel like what Fuba-chan said makes sense!" Yuri sighed.

“………… Makes perfect sense............ "Nuko continued.

"mo~~~ even the floating waves say so! ………… But too! For us nowadays, these arts are more valuable than a glass of steaming water! Qianhu thought carefully for a while and said.

"Chi-chan has finally figured it out!" Yuri said happily hugging Chito.

“…… Got it! Nuko also shouted by jumping from Yuri's arms onto Senno's helmet.

"My head is so heavy............ And you ~ you hugged it too tightly! Although Chito said this, his face was filled with a happy smile.

"Na! In that case...... Let's burn the books too! It just so happens that we can save a little bit on fuel.................. Pain, pain, pain! Before Yuri could finish speaking, the frantic Chito tugged her cheeks.

“………… Can you say that again? Chito said with a dark face.

“………… I...... Say...... Put the book ~~......... I'm sorry! As soon as Yuri wanted to repeat it honestly, she was forced to apologize honestly by the familiar squinted expression of Chito!

"That............ I think we can go down? ”

“……………… Never mind! After listening to the boy's words, Chiho finally let go of the hand that was tugging at Yuri's cheek.

"Hmm............ I'm sorry! ………… Chi-chan, don't be angry! Yuri rubbed her cheek and apologized again.

“………… Books are very important to me, so don't make such jokes next time............" Chido said solemnly.

"Hmm!" Yuri nodded earnestly.

“………… Let's go downstairs with Fubo! ”

"Hmm!"

The three of them returned to the original sculpture art gallery, and under the watchful eyes of the two young girls, the teenagers transformed all the sculptures containing energy into food............
