‘Ripple’ may be a powerful technique to fight demons but it is not omnipotent. This technique made energy similar to sunlight but of course, it was weaker than the sunlight itself but it was enough to turn the demons into ashes.
It might be easy to fight normal demons with ‘Ripple’ but it was different when used to fight the Lower Moon, Higher Moon, and ancestors from the demons themselves.
Haru wasn't sure if they could defeat the demon ancestors with the ‘Riak’ technique but it was enough to make them become stronger. He felt a little regretful as he did not find the instructions of ‘Breath of Sun’ as it had been lost in the past. He recalls in the story that Muzan was almost killed by a user of ‘Breath of Sun’ but in the end, it was almost.
The ‘Breath of Sun’ user did not kill him and they were instead killed.
Haru wanted to meet this demon boss as soon as possible then his Quest would end sooner. He remembers that Muzan had turned into a demon because his doctor had used the Blue Spider Lily on him. He wonders if the flower will grow after they kill Muzan.
“…”
‘That's possible,’ thought Haru in heart.
They were on their way to Mount Natagumo to kill the demons living in that place. They complained a little because the system made no difference when they killed members of the Lower Moon, High Moon Demons, or normal Devils.
That was why they decided to come to this mountain because there were many demons living in this location. They needed to kill 100 demons and they only killed three demons after they came to this word.
“…”
“That's the mountain,” said Shinobu as she pointed her finger.
They saw a huge mountain with frightening air around the location.
Haru who ate ‘Horo Horo no Mi’ was quite surprised because there were no evil spirits in that place. He probably thought that it might be due to the existence of demons that made there no evil spirits in this world.
The world will become unbalanced with the existence of evil spirits and demons.
The humans in this world are too weak, even with their ‘Nafas’ Style because it is not too special compared to most of the techniques in the other world.
Haru wonders if he might be going to fight Thanos or Saitama in the future. He began to think that his strength might not be enough to fight something that could make a human disappear by flicking his finger or defeating anything in a single blow. He did not really want to fight the monster and just wanted to live comfortably with his sister.
Mitsuri sighed as she thought that she could not follow them.
“What's up, Mitsuri?” Rengoku asked.
“I want to know if they are single,” asked Mitsuri.
“Who? Korosensei?” Rengoku asked.
“Of course not, I mean Kasugano-san and Sakata-san,” Mitsuri said.
“Well, you have to try it and ask them if they are single or not, they will come back later after they kill that demon,” said Rengoku.
They had known their strength ever since they spent most of their time training together with them. They know that they are very strong, especially bipedal octopuses. They had been bullied by the octopus for the past week and wanted revenge but it was impossible to do that.
Haru is the most mysterious of them all because it is impossible to hit or punch him. They were not sure but it seemed like this person could read the future. The technique is also very strange and difficult to read.
They were sure to be slaughtered once the three of them became serious, but they had never seen them become serious because most of them would often prank them, eat sweets, or sleep.
“….”
“Mitsuri, I think they both already have someone,” Obanai said.
“Eh? Did ya? How do you know?” Mitsuri asked.
Obanai Iguro is a Demon Killer and Snake Pillar of the Demon Killer Corps. He was a young man with black hair who had bandages curled around his mouth and had snakes encircling his neck. She has a secret that she loves Mitsuri and she does not want Mitsuri to be close to the three of them.
“First Sakata is old enough, he may have a wife in his country,” said Obanai.
“That's right,” Mitsuri nodded.
“And lastly, Kasugano might do it with Shinobu,” Obanai said.
“…”
“What?!” Everyone was shocked when they heard it.
“Do you also think so?” Mitsuri asked. He also realized that the relationship between Shinobu and Haru was very close and their fight was something akin to a flirt.
Obanai nodded, “Ya, that's why you should give up and support Shinobu.”
Mitsuri sighed and nodded, “Alright, I will support her.” She gets excited and will support her friend to get her love.
Obanai nodded in satisfaction.
“Acho!” Shinobu sneezed suddenly before entering the mountain.
“What's up? Are you cold?” ask Haru.
“No, nothing,” Shinobu shook her head. He wondered if someone was talking about it because he became very upset.
“Then let's go,” said Haru.
They entered the mountain together and wanted to kill the entire demon on this mountain.
“There is a group of people who have entered our house.”
They nodded and did not say anything because someone had entered their house then their fate had been determined and it became their family's food.
