Haru knew that the old man in front of her was the former leader of the demon slaying organization. This old man also mastered the breath of water used to kill demons.
“Parent, who are you?” ask Gintoki.
“Before that, Tanjiro shouldn't you have hidden Nezuko?” said Haru.
“Ha?” Tanjiro.
“The sun will be rising soon, it will be bad for your little sister,” Haru said.
Tanjiro looks around but he can't find his younger sister, “Nezuko?!” He walked inside the temple and saw it inside. He breathed a sigh of relief when he saw her in the box.
“I don't know who you are, but can you help me bury a corpse inside the temple?” The old man asked.
They nodded in response when they heard it.
They buried a corpse in the earth.
“Can you tell me who you are?” The old man asked. He was curious how the people in front of them had very different looks and also magical skills that could turn zombies into ashes without swords or poison, ‘Is that an octopus?’ He thought while looking at Korosensei.
“Before you ask our name, why don't you introduce yourself first, old man?” gintoki said rudely.
“Oh, right, I am Sakonji Urokodaki,” said Sakonji.
“Y – You are the one..” Tanjiro suddenly exclaimed.
“You Tanjiro Kudamo?” Sakonji looked at him.
“Yes, it's me,” Tanjiro nodded.
Sakonji nodded, “Giyu Tomikata has introduced you to me, you should follow me after this.”
“Ya,” Tanjiro nodded and looked at the three of them with curiosity.
“Can we follow you old man?” Haru asked and added, “We want to ask you some questions about demons because their existence is a little similar to vampires and zombies in our country.”
Sakonji was a little surprised, “Is there the same existence in your country?”
“Yes, they are also very strong and their weakness is the sunlight which is similar to the previous demon,” Haru said, adding, “We might be able to exchange information.”
Sakonji nodded and also felt a little curious, “Ya, it's okay.”
“Where is your home? I will send you there,” suddenly Korosensei said. She knew from him that the old man in front of her was also a teacher. He was quite curious about the training course or the way this old man trained his students.
“Hah? Send me?” Sakonji was confused.
“UWEEEEGHHH!!!!”
Gintoki and Tanjiro vomit on the side.
Sakonji is better but she is also a little dizzy, ‘A – Who are they?’ He knew that speed was impossible to be recreated by humans. He was no longer sure about them and became even more curious.
Haru looked at the mischievous smiling Korosensei. He sighed and introduced himself, “My name is Kasugano Haruka, the one vomiting is Sakata Gintoki, and his yellow octopus is Korosensei.”
“Nice to meet you,” Korosensei smiled.
“...” Sakonji fell silent and asked, “Your name...”.
“Yes, our ancestors came from this country, so our names are similar,” Haru said. He lay with a flat face.
“Oh, then what are you guys?” Sakonji asked.
“Ripple user?” Sakonji blinked his eyes inside his mask.
Haru might really think that the author of ‘Kimetsu no Yaiba’ was inspired by ‘Jojo’ because their enemies are similar and their techniques are also similar just to different methods to apply them.
Gintoki and Korosensei said nothing because the explanation was very eloquent.
“We are able to produce energy similar to sunlight inside our body, which is why we can defeat demons easily,” Haru said.
“Produce energy similar to sunlight?!” Sakonji thinks that if the demon slayers have that technique then they can defeat the demons easily.
“How about you? Are you using something similar to us?” ask Haru.
Sakonji shook his head, “No, we use something known as breath force, it is a sword technique developed to defeat demons.”
“Interesting, can you let us see this technique of yours?” ask Haru.
Sakonji nodded, “Ya, but can you show me yours too?”
“That's great,” Haru nodded.
Everyone looked at the two of them with curious expressions.
“I'll show you my technique first,” said Sakonji and took the sword at his house. He walked towards the large rock in front of him. He held his sword and took a deep breath.
“J – Don't tell me he's trying to cut that big rock?!” Tanjiro.
“First Style: Water Surface Slice!” Sakonji sent a single powerful slash towards the huge rock in front of him.
It might be their imagination but they saw the illusion of water being sent from that slash.
*Cutting!
The huge rock was split in two by his powerful sword attack.
Sakonji sighed and put his sword in the sheath again.
“Alright, now is my time,” Haru said and walked towards the frog who was resting on the rock.
“A-What are you doing?!” Tenjiro surprised.
Haru has told everyone that they should buy the Ripple technique because it is quite cheap and has many functions in this world. He raised his fist and punched towards the frog, “HAAA!!!”
“STOP!!!!” tanjiro shout.
His fists hit the frog but passed through and cut the stone in half without damaging the frog.
“Attract!” The frog jumped away after the stone split in two.
“…..”
“T – The frog is fine..” Tanjiro surprised.
Haru thought that the Ripple technique would be useful in this world fighting against demons that had a weakness against sunlight. He needed to gather 10 breath force instructions and to do that he thought of exchanging them for this Ripple technique.
The ripple technique could be an addition of the demon assassins who had learned the breathing style to make their attacks stronger to fight the demons.
Sakonji was stunned and unsure what to say because he could feel the goodness in the technique. He desperately wished the demon assassins in his country had that technique.
