Tanjiro was standing at the entrance to the building he and the rest of the Corps members were staying at. He was wearing the uniform of the school, which consisted of a gray button-up jacket with dark blue-green cuffs over a white shirt with a red tie. He, Zenitsu, Inosuke, Genya, and Muichiro wore dark green pants, while Nezuko, Kanao, and Aoi wore dark blue-green pleated skirts. He was waiting for everyone else. He could smell that most of them were up, the exception being of course Zenitsu. He had been up for a couple of hours. He already ate some breakfast and cleaned himself. Judging by scent, Kanao, Aoi, Nezuko, and Muichiro were eating breakfast. Genya was exiting the bathroom. Inosuke was getting forcefully dressed by Mr. Uzui. And Zenitsu was still asleep.
He remembered the long conversations the Hashira, Aizawa, and Nezu had about what they could do while he and the other seven were in school. They were going to be teaching assistants. As for the courses Tanjro and the others were going to be in, they were joining Aizawa's class. Something called the Hero Course. Aizawa and Nezu reasoned that the physical demands of the Hero Course were not as demanding as the requirements for being a Demon Slayer. Also, they were told that Heroes didn't kill anyone unless there was no alternative and that they'd treat demons, if there were somehow any around in this time, like run of the mill villains. Despite protests, Aizawa said that they wouldn't use lethal force unless there was no alternative.
According to the device he and everyone else got, called a smartphone, there was apparently around twenty minutes before they needed to be in the place where Aizawa was. According to his sense of smell, Kanao, Aoi, Muichiro, and Nezuko were washing their dishes. Genya and Inosuke were eating fast. And Zenitsu was still asleep. He began walking toward the stairs to go get Zenitsu up when Nezuko called out for him.
"Where are you going, big brother?" Nezuko asked.
"Zenitsu still isn't up yet. He shouldn't be late for our first day in this 'school' place," he replied.
"I'll get him up. Don't worry about it," she said.
She walked past him and disappeared after the first turn. Tanjiro trusted that she knew what she was doing. He returned to the front entrance.
"Good morning, Tanjiro," Kanao said.
Tanjiro arrived to see Kanao standing at the door, holding her hands together in front of her. To Tanjiro, she seemed to sparkle.
"Oh, good morning, Kanao. You look nice," he said.
"Th-thank you. You look nice, too."
Before they could say more, they heard a very loud scream.
"AAAAAHHHHH!!! NEZUKO!!! YOU LOOK ADORABLE!!! SERIOUSLY, YOU LOOK SO GOOD!!! DID YOU GET DRESSED UP LIKE THIS JUST FOR ME?!? ... AAAAAAHHHHHH, I COMPLETELY FORGOT THAT WE WERE STARTING THAT SCHOOL THING TODAY!!!" Everyone heard Zenitsu scream.
"Could he be any louder?" Aoi asked.
She and Muichiro walked toward the entrance. Behind them, Genya and Inosuke were putting their dishes in the sink. A sound like thunder erupted, and Zenitsu was suddenly in the dining area eating like his life depended on it. Remarkably, he finished up right as Insosuke and Genya made it to the front. Nezuko joined the group just as Zenitsu put his dishes in the sink and bolted over to the group.
"So, are we ready for our first day at this 'school'?" Tanjiro asked.
Everyone voiced an affirmative. They walked out of the building and back towards the large structure they had all woken up in days ago. Along the way, they saw multiple strange people. If they already knew demons shouldn't exist in this time period, they all would have instictually thought the strange people were demons. Bizarre face shapes, strange growths from their bodies, additional limbs. Some even had animal features to them.
