I hope the children can grow quickly under the guidance of the Thunder Hashira.
Kagaya Ubuyashiki waved his hand, signaling that Roa could leave.
He let out a light sigh and looked at the blue sky and white clouds outside. Although the weather was sunny, everyone knew that a storm was brewing.
Roa walked out of the house, passed through a long corridor, and headed back the way he came.
Guiding the Hashiras was now Roa's task.
Without activating the Demon Slayer Mark, there were not many ways to significantly and quickly increase one's strength. Roa could only try his best to help the Hashiras attempt to open the Transparent World.
Fight, guide, and then fight again.
Not just the Hashiras, Roa also found Mitsuri Kanroji and forcibly pulled her over, demanding that she join in the training.
After the initial panic, Mitsuri Kanroji recalled the feeling and, like in the original story, created her own Breathing Style.
The Love Breathing, a somewhat unique Breathing Style.
Although Roa still found it a bit rough, she had carved out her own path, which was commendable.
Later, he could try to teach her the Sword God Style. Compared to the sword techniques of Love Breathing, the Sword God Style's techniques were undoubtedly more powerful. Roa actually hoped that she could adjust her breathing based on the Sword God Style, which would allow her to unleash even more strength.
Finally, there was the Demon Seed.
This thing was an energy pump. Later, he would see if he could take it out of this world. If he could bring it back to the "Mushoku Tensei" world, he could give the Demon Seed to someone.
The "Mushoku Tensei" world had not yet fully unfolded, and being alone in such a vast map was not enough. He needed to have strong and reliable people by his side.
Mitsuri Kanroji's talent was undeniable. Even though her mind was full of love, she had created her own Breathing Style. She was also someone with a special physique. Once such a person came into contact with magic, her combat power would undoubtedly grow explosively.
Therefore, Roa was quite optimistic about Mitsuri Kanroji.
He could also expand the map further. Later, he could throw Mitsuri Kanroji to Paul's side and have her accompany him as a bodyguard, which should be no problem.
However, thinking of Paul's terrible personality, he felt it necessary to give a heads-up.
Although Paul's family status was quite poor, a poor status and lust were two different things.
After the transfer incident occurred, Roa wanted to see where he could teleport to and how the Human God would deal with him.
These were all matters for the future. Roa's thoughts returned to the present. He looked around at the Hashiras who were sparring with each other, nodded, and shouted, "Good, everyone is full of spirit! That young man over there, be more decisive in your strikes. Your Breathing Style is still too immature!"
Roa transformed into a drill instructor, constantly patrolling the Hashiras, pointing out their shortcomings. Of course, he paid special attention to Mitsuri Kanroji, basically keeping his eyes on her the whole time.
Surprisingly, Mitsuri Kanroji, who would usually become extremely shy when Roa looked at her, became exceptionally serious in combat.
Roa nodded, expressing his approval of Mitsuri Kanroji.
Thus, the day passed quickly. Roa lazily sat in a chair, watching everyone train, holding a cup of oolong tea in his hand. Seeing everyone pouring their youth and sweat into their training, he couldn't help but sigh in an old-fashioned tone, "This is youth!"
Tengen Uzui, who was drinking water nearby, couldn't help but roll his eyes and said to Roa, "Kid, you're still young, aren't you?"
Roa nodded, then shook his head.
Tengen Uzui was confused and said, "What do you mean?"
Roa didn't answer but instead said in a proud tone, "I now have three wives."
Tengen Uzui was speechless. He really wanted to retort that he hadn't asked about that, but after looking at Roa's expression, he said somewhat strangely, "Who are the three? I haven't seen you interacting with any girls recently."
Roa pointed at Mitsuri Kanroji, who was training, then nodded slightly and said, "Indeed, she's quite cute. What about the other two?"
Roa chuckled and said, "Back in my hometown."
Tengen Uzui raised an eyebrow and said, "Hometown?"
Roa nodded, then patted Tengen Uzui's shoulder and said, "So, how about my wives? Not bad, right?"
Tengen Uzui pushed Roa's hand away in annoyance, turned his head, and said, "I need to train. Don't let women distract you from your duties, kid."
Then he struck a pose and walked forward.
Time passed quickly, and in the blink of an eye, the day was over. Roa smiled as he sent each Hashira off. When it was Mitsuri Kanroji's turn to leave, he suddenly said to her, "How about staying at my place tonight?"
Mitsuri Kanroji was stunned, and her face turned red again, unsure of what to do.
Roa directly put his arm around Mitsuri Kanroji's waist and said with a smile, "It's fine, let's have dinner first."
Mitsuri Kanroji nodded in confusion and was thus easily persuaded by Roa.
Tanjiro Kamado wiped the sweat from his forehead, his face showing a strange expression.
He thought for a moment—wasn't it different before?
Tanjiro Kamado didn't even need to ask; the way Mitsuri Kanroji was acting was too obvious, and it was so different from her previous demeanor that he felt a bit speechless.
But speechless or not, Tanjiro Kamado still smiled and greeted Mitsuri Kanroji, "Hello, Mitsuri Kanroji sister! What would you like to eat tonight?"
Mitsuri Kanroji twisted her hands together, looking quite flustered.
Roa coughed twice and said to Tanjiro Kamado, "Tanjiro, go ask the kitchen at headquarters for some sakura mochi. Mitsuri Kanroji likes that. If they don't have any, have them make some—let's start with 150 pieces."
Tanjiro Kamado nodded and walked out of the house. Roa then turned to Mitsuri Kanroji and said with a smile, "You can't just eat sweets; you need to have some proper food too. And eating so much at night will make you fat."
Mitsuri Kanroji protested softly, "I won't get fat."
Hearing her rebuttal, Roa chuckled helplessly.
Someone like Mitsuri Kanroji, who ate a lot but also burned a lot of energy, could naturally eat whatever she wanted without worry.
If it were Roxy or the others, eating like this would eventually turn them into little chubby girls.
Roa led Mitsuri Kanroji into the house. Nezuko Kamado was sitting at the table, taking care of her younger brother.
Nezuko Kamado saw Roa and Mitsuri Kanroji and was slightly surprised. She reached out to touch her brother's forehead and said with a smile, "Good evening, Roa big brother, Mitsuri Kanroji sister."
Mitsuri Kanroji and Nezuko Kamado's eyes met, and Mitsuri Kanroji instinctively looked away.
Mitsuri Kanroji was like this—the more flustered she felt, the less she dared to make eye contact with others.
Nezuko Kamado seemed to understand something and chuckled softly, saying to Roa, "You mustn't bully Mitsuri Kanroji sister in the future~"
Kie Kamado walked over from the side and asked, "What would you like to eat?"
Roa said to Kie Kamado, "Carved roast fish, please. The way you cook it is truly delicious. Please add more pork this time, and cook more rice."
Kie Kamado glanced at Mitsuri Kanroji and nodded. Then she grabbed Nezuko Kamado, who was watching from the side, and pushed her towards the two, saying, "Then I'll go get busy. Nezuko, come help me."
Nezuko Kamado's expression became very serious, and she nodded solemnly, saying to Kie Kamado, "Yes, I will do my best to help. Then, please take care of my younger siblings, Roa big brother."
Roa watched their departing figures and fell into deep thought.
Mitsuri Kanroji breathed a sigh of relief. She always felt a strange sensation when she was with Kie Kamado and Nezuko Kamado.
There were still three children in the house. Hanako Kamado looked at the two, ran up to Mitsuri Kanroji, and reached out her hand for Mitsuri Kanroji to hold.
Although Mitsuri Kanroji had seemed quite flustered earlier, in reality, she was usually a very warm and outgoing person, giving children a natural sense of affinity.
Even though Mitsuri Kanroji had only been here a few times, she got along surprisingly well with the children.
After chatting with them for a while, Mitsuri Kanroji quickly became friends with the children. She had younger siblings at home and knew how to interact with children. In no time, she was playing with them.
Roa sat there dryly, watching the children play, and smiled.
It was surprisingly good.
After finishing the meal, Kie Kamado cleaned up the dishes, and Roa pulled Mitsuri Kanroji aside, saying, "How about staying at my place tonight?"
Roa had just tasted a bit of sweetness and didn't want to let her go so easily.
However, while Roa thought this way, Mitsuri Kanroji did not. She shook her head seriously and refused, "Um, tonight might not work. I just remembered that it's my turn to patrol tonight."
Due to her strength and Kyojuro Rengoku's recommendation, Mitsuri Kanroji had already reached the level of a Kinoe-ranked swordsman upon joining, essentially the highest rank below the Hashiras.
Naturally, the status of a Kinoe-ranked swordsman was high, but the responsibilities were also significant. Whenever a demon of the Lower Moon level appeared, the Demon Slayer Corps would send at least one Kinoe-ranked swordsman to lead the investigation.
Therefore, Mitsuri Kanroji's duties were not light.
Roa nodded and didn't say much more. Since they couldn't sleep together, he would at least savor her presence.
His hand skillfully reached for her waist, and with a slight pull, he brought her into his embrace. It had to be said, mature women were incredibly alluring.
Mitsuri Kanroji looked up and met Roa's gaze. Roa caught the scent of Mitsuri Kanroji, which was noticeably different from the morning—the smell of sweat was more pronounced.
But this scent wasn't unpleasant; on the contrary, it even gave Roa some strange thoughts.
Mitsuri Kanroji seemed to sense something and tried to push Roa away in a panic, but Roa's left hand held her firmly.
The movements were smooth and practiced, so much so that Mitsuri Kanroji didn't even react in time.
Fortunately, Mitsuri Kanroji's mind was simple and didn't ask the classic line, "Why are you so skilled?" Otherwise, Roa would have been utterly embarrassed.
Holding her waist, he leaned down naturally.
Then, he lowered his head and gave her a deep kiss.
Five minutes later, Roa finally released his grip on Mitsuri Kanroji's waist.
He reached out and patted Mitsuri Kanroji's head, smiling as he said, "Go on. If you encounter someone you can't handle, run away quickly. I'll be here. The area you're in charge of isn't far from here. If anything happens, just send someone over. Oh, and here's something for you."
With that, Roa reached into his pocket and pulled out a hairpin. The color of the hairpin was similar to Mitsuri Kanroji's hair. Roa wasn't very skilled at styling girls' hair, so he said with a hint of regret, "Although I'd like to put it in your hair myself, I'm not very good at it. Here, take this. Make sure to keep it close to you~"
Mitsuri Kanroji reached out with trembling hands and took the hairpin. The color of the hairpin was very similar to her hair, and she had hardly seen any hairpins of this color in the town. It was clear that Roa had put a lot of effort into it.
In an instant, feelings of gratitude and excitement welled up in her heart. Mitsuri Kanroji boldly kissed Roa, leaving him momentarily stunned. The soft sensation lingered, but it quickly ended. Roa smacked his lips, savoring the moment, but seeing the joy on Mitsuri Kanroji's face, he fell into deep thought.
Do girls really like this kind of thing? I should pay more attention in the future.
However, there was a reason for giving her the hairpin. It was imbued with Roa's magic power. If it sensed a powerful being and wasn't too far away, it could send a message to Roa.
It served a similar purpose to the warning line Roa had set up at Tanjiro Kamado's house.
However, magic is something that needs to be replenished after a week; otherwise, it will quickly disappear and become an ordinary hairpin.
Watching Mitsuri Kanroji bounce away until she disappeared from view, Roa shook his head inwardly.
The sky had darkened, and everyone had their own tasks.
Of course, Roa wouldn't admit to being a slacker; he raised his gaze to the bright moon in the sky.
The hazy moonlight made the moon in "Demon Slayer" appear rounder and more beautiful than elsewhere, but it was also more dangerous.
Roa simply moved his limbs a bit, brought a chair out from inside, and quietly sat in the courtyard.
He released his perception and waited for Muzan Kibutsuji to arrive.
Of course, Muzan Kibutsuji wouldn't appear immediately tonight, but the approximate time would be in the next few days.
With his mental power expanded, everything around him was perceived by Roa. The transparent world opened up, and magic flowed into it. In that moment, every rustle in the courtyard was firmly under Roa's control.
He sensed the movements of the Demon Slayer Corps members; Tanjiro Kamadou was holding the Nichirin Sword, preparing to walk outside, while Nezuko Kamado was talking to the children. Even the movements of the leader were perceived by Roa.
The night was hazy, and wisteria flowers were in full bloom.
Roa sat there for the entire night.
Feeling the gentle breeze of summer and the warmth it brought, Roa began to feel a bit drowsy.
The wisteria flowers emitted a faint fragrance, swaying in the summer breeze, brushing against Roa's golden hair.
As expected, Muzan Kibutsuji ultimately did not appear.
It was understandable; the location of the Demon Slayer Corps headquarters was relatively remote, and finding it immediately would indeed be a bit troublesome, but it was only a matter of inconvenience, far from being difficult.
However, this also showed that Muzan Kibutsuji usually did not take the Demon Slayer Corps seriously, as he didn't even grasp such information in a timely manner.
The training continued as usual. The next morning, Roa, as per routine, provided training to the Hashira willing to come.
After a brief rest at noon, he engaged in some flirtation with Mitsuri Kanroji, and time passed like this.
At night, he stood guard, waiting for Muzan Kibutsuji's arrival. During the day, he practiced, and thus, Roa lived a leisurely life.
Although it was leisurely, it couldn't go on like this forever.
Fortunately, this kind of life did not last long. Finally, on the night of the fourth day, Roa suddenly opened his eyes. He sensed a very evil aura appearing in the room of Kagaya Ubuyashiki. Who else could it be but Muzan Kibutsuji?
However, apart from sensing Muzan Kibutsuji's aura, Roa did not feel the presence of any Upper Moon demons, and he relaxed his heart.
With a movement, his figure transformed into a flash of lightning and disappeared in the courtyard.
In Kagaya Ubuyashiki's home, the room was not large. At this moment, Kagaya Ubuyashiki was sitting on the floor with a pained expression, glaring at the man in front of him.
Kagaya Ubuyashiki said, "Muzan Kibutsuji, how dare you show your face here?"
The man before him had short black hair, a tall figure, and skin as pale as paper. His plum-colored eyes stared intently at Kagaya Ubuyashiki and said, "I really didn't expect to fall to the Demon Slayer Corps twice in one go. I originally thought there was only one Yoriichi Tsugikuni in this world, but now there's also a Roa. I wanted to give you a chance to live like a filthy rat in a gutter, but unfortunately, you didn't cherish it."
Kagaya Ubuyashiki's already pale face became even paler. He pointed at Muzan Kibutsuji and said, "Muzan Kibutsuji, you should not exist in this world. I feel ashamed to have your bloodline flowing in me. The karma of the Ubuyashiki family should end with our generation. Muzan Kibutsuji, I will eliminate you. As an evil existence like a demon, you should not exist in this world."
