"Infinity Train?" Itsuki hastily looked around, "The Infinity Train that Tanjiro and Nezuko were riding on?"
The train is dim.
The whistle blows.
There were also passengers wearing ancient clothes, all of them asleep.
The more Itsuki looked at it, the more familiar it became, and it was quickly confirmed that it really was the Infinity train in Kimetsu no Yaiba: Mugen Ressha-hen.
"Asakawa-san, why are we on the Infinity train?"
Itsuki asked nervously.
Naoki didn't answer, just looked at Itsuki with strange eyes.
Aware of Naoki's strange gaze, Itsuki whispered:
"Asakawa-san?"
Naoki said, "I have a few questions for you."
Itsuki nodded, put his hands on his knees, and sat up straight: "What's wrong?"
"What is your favorite food?"
"I like everything as long as it's delicious."
"Wrong answer."
"Fried chicken."
"That's my favorite food."
Itsuki turned his head away, his face slightly reddened, and she stuttered, "It's meat buns, why are you asking such a question."
Naoki continued:
"What do we eat for lunch?"
Itsuki: "Barbecue Buffet."
Naoki: "Who's the killer in the movie version of Conan?"
Itsuki: "The guy in the trench coat with glasses."
"One plus one equals how much?"
"All elementary school students know about this matter!" Itsuki could only complain "I feel offended!"
"It's almost confirmed."
Naoki had an interesting expression on his face, "You don't know yet?"
"Eh?" Itsuki was surprised, "What did you find?"
"It's an Infinity Train." Naoki stretched out his finger and lightly patted his forehead, "This is also a dream."
Itsuki suddenly reacted.
"I remember… We verified Asakawa-san's ability to fall asleep, and I couldn't fall asleep, and then…"
Itsuki was confused: "Strange, how can I fall asleep?"
"Don't think about it, so far, no one knows when someone fell asleep." Naoki crossed his arms, "If you have to say it, you will fall asleep about 5 minutes after the kiss."
"What?" Itsuki raised his hand to cover his lips and turned his face away in embarrassment, "You promise not to bully me?"
Naoki said confidently: "I just said that Nino and others sent a message and asked me not to bully you, but I didn't say that I agreed."
"This topic ends here!" Itsuki changed the subject, "We appeared on the Infinity Train. So, Asakawa-san succeeded in her dream?"
"Looks like it's a success for now, and there's an added benefit." Naoki nodded lightly and looked at Itsuki "You didn't lose your memory in the dream this time."
"Eh?"
Itsuki was taken aback.
Naoki was speechless. "You haven't realized yet?"
"Of course I know." Itsuki turned around feeling guilty.
Okay.
Actually no.
When Itsuki opened his eyes, she suddenly found herself in an unknown Train. If it wasn't for Naoki by his side, she wouldn't know what to do now, so she didn't have time to think too much.
"This is the first time knowing that you are dreaming in a dream, and it is worth learning." Naoki mused, "The first might be the effect of being able to fall asleep, and the second might be because I kissed you…"
"Definitely not the second!"
Itsuki hastily shook his head in denial.
That kind of thing has nothing to do with dreams!
"Maybe yes, maybe no, jot down all the possibilities for now, and then slowly verify later." Naoki said slowly, "Scientific research always advances through trial and error."
Itsuki complained: "So, this is clearly a superpower, why do you want to involve scientific research!"
"The end of science is theology." Naoki was very interested, "For example the double slit interference experiment, humans haven't been able to come up with a plausible explanation so far..."
"Sorry, I do not understand." Itsuki stood up and looked at the sleeping passengers around her, slightly frightened, "By the way Ichika, Nino, and the others?"
"I do not see it." Naoki shook his head, "I only saw once, and I didn't see anyone."
"Will it be in another Train?" Itsuki analyzed, "While watching the movie, the Infinity train has a total of eight Trains."
"Everyone must be really scared." Itsuki said quickly, "Let's go find it?"
Naoki stood up: "Let's go."
The two of them walked through the narrow alley towards another Train.
The story of Kimetsu no Yaiba takes place during the Taisho period, not long before the train was introduced to Japan, it was an ancient steam train. On the way, you can hear the continuous whistling of water vapor and the sound of the train shaking violently. It was really a nostalgic feeling.
Itsuki was a little scared, reached out to grab Naoki's sleeve and walked carefully behind.
Instead, Naoki didn't care, he pushed the door open, and the movement was very loud in the deserted Train.
Itsuki was surprised, and hastily said: "Asakawa-san, move lightly, don't forget that there is a Demon in the Train."
"You're the one who forgot the point?" Naoki complained, "This is your dreamland. In theory, this is your homeland."
"Even if you say that, I'm still afraid…"
While talking, the two quickly checked the passengers on the train.
"Not." Itsuki's tone was disappointed, "I didn't see anyone... Let's go to the next Train."
After checking two Trains in succession, they still didn't see any of Ichika, Nino, Miku, and Yotsuba.
It wasn't until entering the third Train that the two finally met an acquaintance.
"That's a human…" Tanjirou looked confused, "Why didn't you fall asleep?"
"Eh, Tanjirou?"
Looking at the man with a red scar on his forehead in front of her, Itsuki opened his eyes in surprise.
Tanjirou was surprised: "You know me?"
"It really is Tanjiro." Itsuki turned around, and she saw the little girl following behind Tanjiro, the girl bit the bamboo tube in her mouth "Ah, it's Nezuko!"
When the little girl biting the bamboo tube heard her name, she tilted her head in doubt, and there was great doubt in her burgundy eyes.
"Nezuko is really cute."
Itsuki was surprised.
The dream in front of her was unbelievably real, as if she had actually traveled on an Infinity train. Although she didn't dream of the mother she most wanted to see, but met Tanjiro and Nezuko, Itsuki suddenly felt that this was truly precious.
"Strange." Tanjirou sniffed "Why can't I smell your body?"
"It doesn't really matter." Tanjirou's expression quickly became serious, and he quickly urged, "There are Man-eating Demons on the train, don't run Nezuko, take care of them, I will fight!"
Itsuki hastily said: "The demon is at the head of the Train, and its body has been integrated with the Train. Be careful not to be deceived."
