How to tame the dragon

--- DXD World, Asgard, Roots of Yggdrasil ---

-- Third Person POV ---

- Yggdrasil -

A mythical tree that connecting to the nine worlds, a tree with an unimaginable size that can pierce through the heaven. There were three mythical creatures that live in the Yggdrasil, first was Vedfolnir was a hawk that sat in-between the eyes of an unnamed Eagle at the top of the highest branch on Yggdrasil. This branch, like many things in Norse mythology, had a name. This limb of Yggdrasil is known as Lead. Vedfolnir is an Old Norse word. Second was Ratatosk is the squirrel that runs up and down Yggdrasil each day carrying the insults between Vedfolnir and Nidhogg. Ratatosk does whatever he can manage to do to keep the hatred between the eagle Vedfolnir and Nidhogg fueled. Last was Nidhogg, as mentioned before, is the monstrous dragon that relentlessly gnaws on the third and deepest root of the Yggdrasill. The dragon does this in hopes he can chew through the root. His goal is to cause the World Tree to become unstable and fall.

" Phew, finally I reach this place, Odin was troublesome fellow even he was a pervert," Touru said as he sat down in cross leg to gather a large amount of natural energy, he was trying to communicate to the world three to let him passed through the roots to take out Nidhogg.

-- A few minutes later --

The roots of Yggdrasil was moving very slowly to create a gap that fitted in adult size person, which means Touru was allowed by Yggdrasil to enter to bottom of the World Tree.

" Thanks," he said as he entered through the gap. He used the Trickster Style to advance inside, the inside of the roots was too dark for the human but for the people like him was like a walking in the morning. He can see every detail and structure of roots he ignores it and continued to reach where Nidhogg was placed on. By the time where could feel the life force of Nidhogg, he could tell the distance when he entered the gap it almost 10km from the gap till the place that he was currently in.

" *Sigh* I didn't think that this place was too large, especially this is only a root part not including the entire body of the tree," he said as just only walk towards the thick root with a hole that could manage to fit the Van. He guesses that it might be a hole were Ratatosk was coming in and out to pass the insult against Vedfolnir and Nidhogg. Upon the time when Touru entered the hole, he found the vast place with a gigantic Dragon who was chewing the roots of Yggdrasil, which the latter noticed his presence he stops eating the roots move his neck towards Touru.

" Rrrrooaaarrr!!!!!" Nidhogg roared towards him that made step back against the pressure of the Dragon Roar.

" Ow it hurts." he lightly said as he poking his ears to ease the pain almost took his sense of hearing, after that he looks at Nidhogg, he noticed that the eyes were a bit familiar to him. This is the same case to Lisa when he first encounters her, a vast amount of negative emotions than Lisa was emitting out from its body. Because Nidhogg was not bounded like Lisa he cannot make sure that he can purify Nidhogg.

" Then I have no options than to fight you huh, time to test this against you," he said as he took a familiar stance, it was Royal Guard stance as he summoned the Rebellion on his back.

" Come on lizard!" he taunts Nidhogg was who get madder when Touru said the Lizard, one of the most biggest insult for the Dragon.

" Rrrrooaaarrr!!!!" once again Nidhogg roared again this time, he charged towards Touru as he uses the right hand with claws that filled with corrosive venom towards him.

" Royal Guard: Royal Block!" Touru said as his body was emitting a large amount of demonic energy to create a circular like shield in front of him.

* Baaaaaannnnnnggggggg!!!!!*

The impact made him step back a little as he managed to block the entire claw attacks from Nidhogg. The latter when he noticed that his attack was blocked, was enraged as he releases more attacks relentlessly to Touru, as former was able to gather the strength to finally countered the attacks.

' Royal Guard: Release!' he finally notices that he can use the Royal Guard without saying aloud its name. As the pent up anger was released towards the neck of Nidhogg.

" RrrwaaaAaarrrww!!!" Nidhogg cried out in pain as he still attack him.

' Royal Guard!' Touru take a stance again as he was ready to use Nidhogg as a training dummy.

--- A half-hour later ---

Finally, Nidhogg was out of the cold as he collapse in the ground. While Touru was still unscathed in the "fight", he can use the Royal Guard a bit instinctively as he can perfectly block the entire attack from them being around Ultimate Class Strength and alter the attack from the being with a strength of Super Class. Touru walks towards Nidhogg to prepare to purified him to get back him to normal without an anger issue.

' Purification ' he muttered in his mind as he gathered a large amount of natural energy/chakra as he borrowed through Yggdrasil. As he gathered enough to purified Nidhogg, a whitish-green light was covered the Dragon around its body. After a few minutes later the light was cleared and another darkish green was covered the dragon, after few seconds the light was also cleared instead of a large Dragon it was a little girl around 14 was lying in the ground and naked, Touru was shocked in revelation from what he saw.

" I thought that this dragon was he, it turns out that the dragon was she, I will take note that does not believe in the history books ever," he said as he took out a blanket from his space pocket and covered the little girl with it, a half-hour later the little girl has to wake up as she saw Touru, a fear-stricken on her face as she was retreating backward.

" No! don't hurt Nidhogg!" the little girl said as she was retreating again.

" I'm not here to hurt you, I'm here to release you from this tree," he said to the little girl.

" That's a lie, Ratatosk said that Nidhogg cannot get go out in this place, if it does the people in Asgard will hunt Nidhogg and cook Nidhogg body for them." the little girl or Nidhogg said as she was shaking in fear.

" About them, don't worry about it I am strong enough to fend them while I will release you from here," he said as he managed to get near to Nidhogg as he took out a Lollipop from his space pocket, the reason why he got sweets from his space pocket it because Shirone was requesting him as she was not able to create a space pocket on her own which is sadden her.

" Here, take a taste of it I'm sure that it was better than eating the roots," he said as Nidhogg was looking at the lollipop on his hand with curiously as she looks between the Lollipop and Touru.

" Really?" she asked hopefully as Touru nodded his head as took the cover from the lollipop as the waft of sweet smell coming from the lollipop was entered to her nose as she took the lollipop from his hand as she put it in her mouth, after a bit licking she was surprised from the taste of the lollipop.

" Delicious?" he asked as Nidhogg was nodding frantically at him.

" There was many of that in the outside of Asgard, I can buy it as many as you want." he was tempting her as he continued.

" If you join me, you can taste the food that better than the roots in your life."

" Umm..." Nidhogg was silent but still licking the lollipop, after a few minutes Nidhogg looks up to Touru with determination in her eyes.

" Nidhogg will join you, umm what is your name?" she said.

" I'm Touru Kamagiri I am White Dragon Emperor in this generation as well as the Cat Deity," he said as he showed his Nekoshou form to her which is surprised her.

" White Dragon! it means you are also like me?" she said as Touru nodding towards her.

" Nidhogg was finally found a fellow Dragon, Nidhogg can finally eat more than the roots," she said as she stood up and trotting cutely towards him as the latter patted her head which she feels good as she wants to be patted.

" Then here we go we will go out in this tree," he said as he summoned the Yamato as he slashes the space in front of him which Nidhogg was surprised as she hides behind him.

" Don't worry it's not harmful to us we can go through this," he said as he gently pulls her hand and walk towards the spatial tear and they vanished from the roots of Yggdrasil.
