Rise of the Immortal Black Dragon King

Kouske's POV
I was currently sitting with the Azusawas in their house. We were having dinner. There was a small chitchat going on between me and Asagi's parents. But Asagi wasn't talking at all. I could see her still being angry because of what happened earlier today.

After dinner, Aunt Arene brought some ice creams for me and Asagi. I could see Uncle Leon staring at them but because of Aunt's glare, he would just look away.

"It's a treat only for the children," Aunt said cutely while she was eating a cup full of ice cream. I would later find out Uncle Leon has a mighty sweet tooth. So he eats an unhealthy amount of sweets behind Aunty's back.

Asagi must have inherited that from him. I just look at her eating in pure bliss. She looks cute. When she noticed my gaze, she would just pout and look away while letting out a cute 'hmph!' '-like noise.

After finishing the sweets the atmosphere changed. Uncle and Aunt both looked serious.

"Miyamura-kun. Do you believe in the supernatural? " Aunt asked.

I raise my head to her question.
"Are talking about magic?"

"Yes, Miyamura-kun. Demons, angels, Gods, youkai whatever you've ever heard of is real. They live among us. I know it's hard to believe but...." Uncle was saying all that with a serious expression

But interrupted him mid-sentence.
"I do believe in them. I know about their existence"

"What?! Where did you learn from?" Uncle Leon said.

"Well, Vritra told me," I say innocently.

"What?!" Uncle asked in shock.

I let out my jet-black wings. It blinks as Vritra speaks out.

"Hello, Azusawa family. It's a pleasure meeting you"

"V-vritra?!"Uncle exclaimed in fear. Vritra wasn't known as an evil dragon for nothing.

"Fufufu!There's no need to be so scared little one. I can't bite inside this thing" Vritra says sarcastically.

"U-umm..yes.Sorry, but how are you...what should I say..."

"Whole?"

"Yes. I heard your soul was torn into different parts and sealed inside numerous sacred gears"

"That's true. But somehow this child managed to awaken a part of my consciousness via one of my sacred gears and then the others automatically came to me" she replied. We had already made up an excuse beforehand if we ever had to explain ourselves.

"Oh! So do you have all of your soul and sacred gears together?"

"Hmm. They are all perfectly pieced together"
Vritra replies with glee in her voice.

"Another Longinus?" Uncle frowned a bit while muttering softly.

"How much of her abilities can you use Miyamura-kun? " Aunty asked from the back.

"I can only use her cursed flames for now," I said while manifesting Vritra's flames in my hand.

I heard Asagi murmuring something about 'how cool' while looking dazed.

"Blaze Black Flames, huh?" Uncle said.

"Does anyone else know about this?" He asked looking serious.

"No"

"Don't let anyone know for now Miyamura-kun. It would be extremely dangerous for you." Aunty Arene said.

"Yes. A few months ago there was a huge uproar in the supernatural community because all of Vritra's sacred gear was suddenly lost. It was a trending topic on the DeviNet for a while." Uncle added in.

"Don't worry. I won't let my host die so easily" Vritra said in a sharp voice with pure determination.

"Hm...Miyamura-kun, you should continue trying to improve your power. Being the host of the Black Dragon King will make you the center of attention in the supernatural. "

"Hm"

"If you want we could help you get stronger. We help you train alongside Asagi as she trains her Senjutsu" Aunt suggested while Asagi looked excitedly at me.

"Senjutsu?" I feigned ignorance

"Yes. You see, we are not human. We are tiger youkai.All youkais can naturally use Senjutsu.While it's not impossible, it's still extremely difficult for races other than youkai to learn it. It is our main fighting style" Uncle said while letting out his youkai form. Aunty did the same. Asagi looked worried for a bit as she looked into my eyes hopefully but did the same.

"Oh. Asagi-chan looks cuter in this form " I said to dispel her worry.

Uncle and Aunt just smiled while Vritra started laughing boisterously.

"Fufufu!"

Asagi seemed relieved that I treated her the same and smiled bashfully. We talked for a bit longer. Then I went home deciding that we would be training together every day early in the morning. That day I went straight to sleep.

It's been a few weeks since then. I have continued practicing with Asagi in the mountains early in the morning. It was my first time fighting a humanoid and experiencing how a tiger youkai fights.

Uncle was very agile and fast. He would cover his body and nails with tiki while using senjutsu. He would lunge at me with his sharp nails and teeth acting like a berserker while I would try to dodge. I couldn't win even once.

After that, I would start sword practicing alongside Asagi. It seems Aunt Arene is a swordswoman. So learning from a real swordswoman has been very effective.

They were surprised to see how powerful my healing was. They thought it must have been Vritra's.

After practice, we would take a small break together to get ready for going to school. Asagi and I have become even closer after learning about each other's secrets.

After school, I would spend my afternoon playing with Irina-chan. Though one big chance is Asagi started tagging along. Irina-chan and Asagi would have small arguments now and then but I can see them becoming a better friend and accepting each other.

I think Asagi still doesn't know Issei's name. She would only refer to him as a pervert, mimicking me. She would look at the pervert with disgust whenever he's at his antics and stay further away from him. Issei tried befriending my cute Asagi-chan with a grin on his face but after seeing the glare in both of our eyes he backed out immediately.

Other than that I have also been meeting with Momo. She would come to my house occasionally to learn magic. I would spend hours teasing and teaching her magic. I plan on teaching her mostly wind magic, hypnosis, and teleportation. The last two are a must in the supernatural.

Until this point, I've tamed nearly 1500 times. I only found two rare slimes in these weeks. One was a wind elemental and the other was a water elemental slime. So I have all four basic elemental manipulation skills in my status. I've finally started searching for the dungeon boss of this dungeon. I want to unlock the next dungeon.

So life has been pretty hectic recently. I'm always busy with something.

But the most important of all is that the gangsters have finally located Lavinia's location. It's time to scoop her up before Glenda.
