Slayer Hero: Tanjiro

Getting Started

When Tanjiro was introduced to Class 1-A, he discovered all the unique quirks and personalities of the other students. Additionally, he found out that Kacchan was just a name Izuku used to address his friend from childhood. His real name was Katsuki Bakugo.

Tanjiro enjoyed meeting everyone and got along with them great. After a while, though, Tanjiro had a few concerns for the boy named Minoru Mineta and his perverted obsession. But for the most part, the introductions went great. Everyone was glad to have Tanjiro as their new classmate (except maybe Katsuki).

"We have training tomorrow! Better get some sleep!" Tenya put his glasses back into place before walking off to the dorm rooms in a robot style.

"Right, it was nice meeting you Kamado," Momo said with a kind smile on her face, "I left some blankets out for you, if you need anything just come knock on my door."

"Thank you very much," Tanjiro bowed in appreciation.

Everyone said goodnight, then left for their dorms. Tanjiro layed down on one of the sofas in the common area. There were blankets folded in a pile next to it. Tanjiro picked up the one on top of the pile and spread it over himself. Then he leaned back and rested his head on the armrest. He was glad that everyone in his new class welcomed him. They were all good people. But Tanjiro couldn't help becoming upset after he thought of Nezuko again.

What must've happened to her? Tanjiro thought to himself.

It was still a mystery how he ended up in this strange new reality, so Tanjiro was focused on finding out how he got there and how to go back. Hopefully, there would be a way, somehow.

Tanjiro closed his eyes and drifted off to slumber. He would become a hero alongside the students in Class 1-A. Maybe that would help.

~{Timeskip}~

Once Tanjiro awoke, he immediately folded the blanket he was using and placed it carefully on the top of the pile.

"Good morning, Kamado!"

Tanjiro was startled by this sudden greeting. Tenya was sitting at a table near the kitchen wearing his school uniform.

"Oh! Good morning, Tenya." Tanjiro stood up and smiled.

"You'd better get your uniform on. We should get to class soon."

Looking around the room, Tanjiro responded, "But... we're the only ones awake."

"It's always good to be at least 3 minutes early!" Tenya stood up from the table where he was seated at, "Most of my classmates don't see it that way, which is why either me or Yaoyorozu are the first ones to wake up in the morning."

"Oh ok," Tanjiro smiled again, "I suppose I'll take your word for it."

Tanjiro grabbed ahold of the case that Izuku had given him and went to the restrooms to change. Inside the case were his UA uniforms.

When he exited the restrooms after getting dressed, Tenya had already left, and others were beginning to crowd the common area.

"Ayy, good morning Kamado!" Denki said once he saw Tanjiro.

"Good morning!" Tanjiro smiled.

Some people were already leaving to go to class. Tanjiro remembered what Tenya said, so he decided to follow. Izuku caught up to him, "Hi Tanjiro, I see you're all ready!"

"Yep!" Tanjiro responded, as the two of them walked to UA high.

Izuku led Tanjiro to their class. The door was large with the words "CLASS 1-A" printed across it. Izuku opened the door to reveal some of the class gathered there. Tenya was attempting to calm the chaos between Katsuki and the other students when Izuku and Tanjiro sat down. Izuku offered Tanjiro a seat next to him, in which Tanjiro agreed with a smile. As more students arrived, the classroom became more chaotic... until Mr. Aizawa walked in.

Mr. Aizawa entered with a tired and serious expression. "Everyone to your seats."

Immediately, the whole went silent and was seated. Tanjiro was amazed by this sudden act of obedience.

"As you all know, we have a new student. Remember, that won't slow anything down, though. We'll be heading to one of the training facilities, so put on your hero costumes and meet me there." Mr. Aizawa said before leaving.

Everyone got up from their seats to head to the locker rooms, where their hero costumes were stored. Once Tanjiro arrived there, Izuku showed him his locker. Tanjiro opened it to reveal a case with his new hero costume.

Once everyone had changed into their hero costumes, they met at the training facility Mr. Aizawa had mentioned.

"Today, we'll be doing more work with your ultimate moves. Go ahead." That's all Mr. Aizawa said before he began walking away to an old, shrivaled, blonde guy.

As students began training with their quirks, Izuku offered to help Tanjiro start coming up with ultimate moves. He explained that ultimate moves were specific attacks you would use to bring down an enemy.

"Oh, I already have some of those then." Tanjiro reassured Izuku.

"You do?"

"Yeah, I'll show you."

Tanjiro approached a large boulder that reminded him of the one at Mr. Urokodaki's residence. He grabbed ahold of his katana and closed his eyes as he concentrated on his breathing. Jumping into the air, he said, "Hinokami Kagura... Clear Blue Sky!" Tanjiro spun his katana in a circular motion as it cleanly sliced the boulder in two.

Izuku's jaw dropped as he watched in awe. As soon as Tanjiro landed on the ground, Izuku pulled a notebook and pen from his pocket and started asking questions. Tanjiro was a bit confused about how the notebook fit into Izuku's pocket, but he answered his questions anyway.

Other students stopped what they were doing after they saw Tanjiro's stunt.

"Woah, man! How long have you known how to do that?!" Eijiro asked.

"Yeah! That was super cool!" Ochako added.

Everyone was fascinated by Tanjro's ability. Eventually, so many people began to crowd around Tanjiro, that Mr. Aizawa had to tell everyone to get back to work.

For the rest of the day, class 1-A had more training and other school subjects. Once the sun began to set, the class was back in their dorms, saying goodnight to each other. Tanjiro was glad that his first day went so well. He wasn't able to gather information on how to go back to his time period, so that's what he would focus on the next day.

Tanjiro was sitting on one of the sofas in the common area, listening to Izuku talk about different heroes. That was until he picked up a revolting stench coming from somewhere outside. It was a smell that Tanjiro thought he wouldn't have to smell here, in this time period. Tanjiro stood up, forgetting that Izuku was talking to him. Tanjiro sniffed the air again to confirm his assumption. There was no mistaking it this time. He knew that he had to retrieve his hero costume again, at least his katana. Because the horrifying scent that Tanjiro could smell was.....

A Demon.
