"The tests have been quite well so far," Nior nodded, satisfied with the power of Breathing Styles.
"Our current spells and arts are too destructive, my lord. We need to develop more techniques like the Breathing Style that Vampires can use in normal situations," Sebas standing by his side, expressed his views.
It is true. Nior himself built most of the Vampire arsenal. He is already infamous for his aggressiveness. Something made by him is naturally fierce, including the vampires themselves.
"Don't worry about that, we will come across many unique power systems during our travels. Although they cannot compare to our spells and arts, we can modify them slightly," Nior was in a good mood. Like the good lord he is, he left future problems for his subordinates to handle.
As they walked toward the place where Kie was, Nior and Sebas kept discussing the finer details of Blood Breathing.
"Nior-sama, I didn't know you were so powerful," Kie exclaimed with both her hands on her chest.
"Haha... It's nothing. Just some casual practise," he smartly shrugged it off.
Kie then turned toward the new person by Nior. Like him, he was wearing unusual clothes, with white gloves. But a single glance at the fabric showed it was expensive.
"And who is he?" Kie asked curiously.
"He is Sebas. He is my butler and also a companion on this journey."
"It's my honour, my lord," he replied with a deep bow.
Being called 'companion' made Sebas really happy.
"Nice to meet you, Sebas-san. I am Kamado Kie," Kie greeted him with a warm smile. Nior had helped them a lot. Anyone related to him deserves utmost respect.
Sebas gave a gentlemanly bow and said, "I am Sebas Valentine. Nice to meet you, too."
Now, the thing was that neither Nior nor Sebas knew Japanese. Nior could communicate due to his Divine powers, allowing him to sense the intent of anything, as well as forcing others to understand what he is saying.
Sebas was having a hard time in this world since he didn't know any spells to translate speech. Most of the time, he communicated through his Charmed servants or inferred what the other person was saying.
"You both have the same surname. Are you two family?" Kie asked curiously. She was confused. From the looks, Sebas clearly acted as a servant, so why do they have the same last name?
"Actually, all members of House Valentine are granted the last name of the lord. This custom excludes lower-ranking servants," Sebas explained calmly.

(Nior POV)
While talking with each other, we reached the foot of the mountains of our destination.
Sebas stopped by my side. He made a slashing motion with his hands, tearing the space open in front of him. From inside, he took out an expensive glass jar filled with shining red liquid and another package.
Handing me over, he said, "I will take my leave now, my lord." He bowed deeply and teleported.
"He disappeared!"
Kie's eyes were wide open.
"Why do you look so shocked? Obviously, my servants can do magic." I replied nonchalantly.
By now, she was used to my answers and did not try to pry further.
"Won't he stay for dinner?" Kie asked, eyes still fixed on the place where he disappeared.
On the way back, she already learned that Sebas takes care of my mansion in Tokyo.
"He has other businesses to take care of. Next time, he will surely join."
I said as we walked toward the house, where Nezuko was resting. The sun will set soon, and Tanjiro's training will be over.
In my hand is the best blood vampires can get on Asgard - the blood of Asgardians.
In my other hand, I am carrying meat from one of the most difficult to hunt animals on Asgard. It is very costly, too. The name of this animal is Hraelvyr. It was found near valleys, and its size helped it to run fast and hide from predators.
To celebrate the successful development of Blood Breathing, we feast today!
When we finally reached home, the sky had already darkened. Tanjiro and Sakonji were already back, making the preparations for dinner.
"No need to cook. Tonight, I will make dinner." I say and raise my hands to show the things in my hands.
Smelling the fragrant blood, Nezuko crawled towards the door and looked around curiously. Finally, staring at the jar in my hands, saliva coming out of her mouth.
"How can I leave you, Nezuko, when we are having something good?" I chuckle and pat her head.
Feeling my touch, she closed her eyes and enjoyed the headpats.
Then I handed over the jar to her. She opened her mouth, revealing her two little fangs. Usually, it would terrify anyone, but to me, they looked rather cute.
Gulping down, in a few seconds, she finished the entire jar. Wiping her mouth, she smiled and rubbed her cheeks against my hands to show her gratitude.
'Hmm... it feels nice'
Nearby, the other three people in the house looked at the scene, having no idea what was happening.
"Is that human blood?" Sakonji asked seriously.
"Kind of, but way more expensive. Well, now that her meal is over, we should start making the preparations for our own."
I took out the meat and went outside to roast it over the fire. I could hear the voices of the three talking, but didn't care too much about it.
The meat was directly roasted over the fire, which I conjured with magic. There was no need for any spices. The natural taste, slight hotness, and just the perfect amount of natural sweetness, including the fat, was itself the best seasoning. Anything else would only ruin the taste. This is how it was eaten in Asgard.
When I returned inside with several plates of roasted meat, the other were already sitting on the ground.
"It smells good," Tanjiro was the most excited for tasty food after the harsh training of the day. He would find even a simple cooked fish delicious. Life as charcoal sellers did not allow them to eat plenty of meat. Even growing vegetables was difficult at such heights.
"I have never tasted a meat like this," Sakonji was also impressed.
"It's not from around here," I answered plainly.
Taking a bite, I couldn't help but close my eyes and enjoy the taste.
'No matter how many times I eat, it amazes me every time.'
After dinner was over, Kie took the plates to wash them. I walked outside and looked at the sky.
'Thirteen per cent of the world is already integrated. With Sebas working overtime, the work will be done soon.'
'But it's still boring staying here. Tomorrow, I will give the Demon Slayer Corps Headquarters a visit.'
As I imagined their reactions, a wide grin appeared on my face. Sharp and ferocious fangs extending down the jaws, they looked nothing like any other demon's fangs.
