Surya had a comfortable look in the hot spring, while Amane was gasping for oxygen by his side, her entire body covered in his sperm. Surya had just fucked her for nearly two hours, completely fulfilling her fantasies. Surya wanted to continue, but he held back. It had been two hours, and Mitsuri could be waiting for him.
"Amane, I am going down."
"Hmmm...."
Amane responded with a shaky voice. Surya walked down the mountainside. He felt his body becoming stronger and checked the data in the System panel. All of his stats have surpassed 10,000. Each point of strength equals one ton of strength. Surya can strike a mountain with his current strength and has perfect control over his body.
When he reached his home Kie Kamado stood in front of his residence. Her eyes were a little hesitant.
"Miss Kie, what happened?"
"Ahh...Surya-san..."
"Are you waiting for me, Please come in?"
When they walked into the house, he noticed Mitsuri was relaxing.
"Surya, you're here..."
"She...is..." Mitsuri noticed Kie and questioned him.
"Mitsuri, prepare some tea."
"Ok."
After that, she entered the kitchen. Then Surya led her to the hall, where they sat.
"What's happened, Miss?" Surya offered Kie a cup of water. Kie took a sip of water and talked about it. She simply expressed gratitude for his help. Mitsuri also arrived with tea. Surya told the incident with Kie to Mitsuri. Mitsuri was likewise saddened after learning what had happened to Kie. She simply expressed her condolences.
Kie explained her presence. She was new to the area, and Kagaya advised her to stay calm. But Kie cannot accept this, and she must do something to overcome her sadness. When she heard that Surya was constructing a new house, she arrived to work as a maid in his home.
Surya agreed to her proposal after hearing it, and Mitsuri did not object. Kie thanked him when she heard his response. After that, Kie left the house, and Surya began to oversee Mitsuri's training.
*********************
The next morning, Surya awoke to warm sunlight and glanced at Mitsuri, who had entwined him like an octopus. Surya didn't fuck her last night and instead cuddled with her. He entered the room after hearing some noises in the kitchen. He noticed Kie was preparing some breakfast. Kie moved into their house yesterday evening.
Surya left the house after washing up and eating a quick breakfast. He went to the Butterfly Mansion. Last night, he sensed Kanae and Shinobu had returned to the mansion. When he left them, he wrote a simple letter explaining why he was leaving, but he needed to know whether they were angry or not.
He entered the butterfly mansion and observed the sleeping sisters. Then he snuck into their bedroom and jumped between them.
"Ahhh...."
"You...."
When they realized there was someone between them, they both yelled. After realizing it was Surya, both of them relaxed. Their eyes shone with excitement. They just hugged him.
"Aren't you mad at me?"
"Somewhat...but we also found out the situation."
Both of them got angry when they saw the letter. When they returned to the Butterfly Mansion, they discovered more about the Kamado family. Nezuko was in the Butterfly Mansion alongside Aoi Kanzaki and Kanao Tsuyuri.
They learned about the Kamado family and how Surya went to save them. Both sisters understood what it meant to lose a family member and treated Nezuko with great care. Nezuko is approximately the same age as Aoi and Kanao. They all got along well with each other.
"So, when will you allow us to Mitsuri?" Both sisters gazed at him. Surya was also astonished and spoke.
"You can meet her for as long as you want; I will not stop you. Just get along, don't fight."
"Hmm...," they both snorted. Surya stopped talking. They each have their personality and behavior. Although Surya could make them obey and modify their opinions, Surya did not want to. Surya will be content as long as they get along, even if they have internal conflicts. After some cuddling, Surya soon left the butterfly mansion.
Surya handed books to Kagaya yesterday that contained information regarding Demon markings and the red sword. After reviewing the information, Kagaya decided to organize a Hashira meeting. Importantly, the surviving Hashira are unaware that Kagaya's body has been healed. Everyone is outside in their allotted location to fight demons.
Demons' activities had slowed slightly, but some were still looking for Surya. Hashira also saw that the demons' activities had lessened and that the majority of demons had gone into hiding in the forest. This time, Kagaya convened a demon slayer meeting to inform them about the Demon Slayer mark and the red sword.
Surya entered the training grounds and watched the twins practicing their swords. They are Yuichiro and Muichiro.
Both brothers opted to stay at Demon Slayer Headquarters for their safety. After meeting the demon slayers, they learned more about them. They observed how powerful the demon slayers were, but even they were hurt in the battle against the demons. They both recognized how deadly the world was when it was full of demons. They agreed to join the demon slayers, despite Yuichiro's opposition but Muichiro convinced him.
"Both of you agreed to join the demon slayers."
Both brothers turned to Surya when they heard the voice.
"Who are you...?
"What, don't you remember me?"
Both were struck by his words and recognized that, at the end of the illusion, they had heard the same voice.
"It's you..." both of them said once more.
"This is your first day of swordsmanship training.
Both of them stopped and nodded.
"Okay, I'll train you from now on."
"Why..."
"You're also aware that the demon slayers have a particular rank known as Hashira, and both of you have the potential to become Hashira."
After hearing what he said, they remembered the descendants of the first breath user, and Muichiro saw himself as Hashira in the illusion.
