Betrayed Thunder God of anailation and destruction

You are my rival

(Dreamscape, Inside the Boosted gear)
Issei arrived in a white world where belzard along with the previous Hosts were standing in front of him.
"So you are ready to go through the training we have planned for you and I never expected you two to show up here, "He said pointing to his back where
Thor and Shiva were standing.
"We also want to train issei in his Dreamscape as it is safer here. I will be training him in weaponry along with Norse Magic after he gains control of his black Thunder" Thor said grinning.
"I am here to train Issei in controlling his Destructive Thunder. Both of our powers have similar properties so I can help him with controlling the amount of destructive power he is infusing into his thunder. After that Thor can take over his Training with thunder along with Norse Magic" Shiva said
"Anyways Meet your new trainers," he said pointing to the 6 previous hosts who were standing behind him."Since you are in Naraka you have enough sparring dummies. when you are awake you will go fight against the monsters in Naraka while when you are here you will be taught the different arts we have for teaching you"
"My name is Elsha im Draig's second strongest and only female host . Im also Asgardian Valkyrie and i was a General in north side of Asgardians realm . I would love to train the son of Thor . I will teach you norse magic which and also some barrier or illusions destroying magic requires calculations and can destroy any kind of barrier or illusions"Elsha said much to issei's surprise.
"Well i never thought i will see you here of all places " Thor said with a smile.
The other hosts were ninga hatori , shoko tadoroki, Jackie Chan.
"So that's it for the introductions and tell me Issei are you READY!" Belzard said in a serious tone with an emotionless expression.
Issei currently was feeling happy, so many people were ready to help him to grow will master everything they will teach and become the strongest. Now he can't wait to see the ORC again with his new skills.
"I will be in your care so please teach me well," He said bowing to all with his tone serious. His eyes were of the one who wants to rise, who will rise to become the strongest to exist, the person to show who is boss."Very well then let's start then. I hereby welcome you to Hell"Everyone had a bloodthirsty grin plastered on their face even the smiling Jackie chan's face was like a Demon's grin.
'I hope I survive but I have to'
{I will be the judge for that} Ddraig said.
(36 months later, Naraka)
Thor, Issei and Shiva were packing their bags putting them inside pocket storages.
Today was the day they were going back. Issei had unlocked the flames of purgatory which were the original flames of Draig. His mastery with Ice and fire magic went far and beyond than the other arts of magic he learned due to his God-like affinity for Ice and fire  magic making him a literal master at Ice and fire magic much to Draig's Surprise due to him being a fire dragon.
While he wouldn't be called an expert in Norse Magic, He is definitely not that bad but in thor's opinion Issei is more of a strength and support type fighter compared to Magni who is a genius in about 20 forms of magic making him far superior to issei in terms of magic and versatility of attacks like a ultimate wizard class While Issei doesn't have much expertise in Magic his physical fighting skills due to Jackie chan's training and destructive capabilities of both the Boosted Gear and his thunder cannot be equalled by Magni anytime soon.
After 6 months of intense physical training he also awakened natural touki,When combined with busoshoku no Haki he becomes a walking tank along with his body immune to most magical attacks which can vaporise a normal ultimate-class being. He can also fly by using his Ki, letting it out of his body like an also uses his Ki to condense his Thunder into small pellets covered in Ki. His body also went through a huge change, all the excess fat on his body was gone replaced with perfectly chiselled muscles and a well built 6 pack. His height also rose to 6 feet 2 inches, the same as Magni's height along with his build. Now if someone were to look at both they won't be able to find many differences between the two.
"Okay Issei you passed this hurdle but you have a worse thing coming, "thor said with a big grin making Issei grin. By living with 2 bloodthirsty people who hide their battle lust very well he also gained a liking for battle but not to their extent so he does like to get into a few battles.
"You have to go through the boring lessons on royalty your mother and grandma will be taking. I still remember the time when I had to fight quarter of the royal guards to run away from your grandma's lessons"thor said stroking his beard thinking back when he was a little brat.
"It won't be as difficult as fighting against a horde of monsters with just your bare fists" he retorted making thor snort annoyed.
"Thank you shiva for helping me with my training, because of you I have full control over my thunder and also was able to unlock and master my God mode," Issei said with a smile grateful for the help he received
Shiva simply waved it off and said "Don't think much about it I also had fun training you. You are truly a worthy opponent and unique Host of the Red Dragon Emperor,issei Thorson from this day forward you are my rival so i want you to get stronger don't let me down ise.I will be keeping an eye on your future progress ."
"Yes before you end up reading my mind and predict my future completely "issei said with a chuckle.
shiva laughed hearing his protege's accusation.
"I neither deny nor agree to that fact but you are too easy to read Issei"
"Okay it is time we go back I miss my Barrel of Ale and I want to drown in a pool of it, "Thor said as he opened a magic circle below each of them teleporting them all back to Mount Kailash.
(Mount Kailash)
The three Gods arrived back at Mount moment they arrived they felt a dark aura emitting from a woman standing in front of had pale white skin and jet black hair and eyes. She had a perfect buxom figure and was wearing a bluesaree.Currently, she was glaring daggers at shiva who started to sweat profoundly"
Husband how dare you leave old little me all alone to watch Netflix for three days." she cooed in a sweet sultry voice which made shiva shiver in fear.
She slowly walked towards him and teleported away before whispering something in his hear which made his face go pale in fear.
"Hoho you two are back"
From the bushes, a short white-haired child came had fur all over his body and he was smoking a cigar. His face was wrinkled and was wearing monk's cassock. He was also carrying a staff along with prayer beads hung around his neck, He was also wearing a sunglass with a cypher like design.
"Hey Sun Wukong where were you gone and where's Indra," Thor asked with a mock hurt voice.
"Indra ran away somewhere and no one knows what he is up to these days. Sorry for yesterday this brat Yu Long ran away to some country yesterday to try out some food and I had to search for him before he caused ruckus down there," He said with a sigh before his eyes landed on Issei who started to hide his power and aura.
"Kid you have good control over your aura and you are somehow able to hide from me My name is Sun Wukong, The first monkey king and also Indra's Vanguard pleased to make your acquaintance Son of Thor and the Red Dragon Emperor. Indra told me about you having the boosted gear and you managed to hide your draconic aura, It is a great achievement by itself to hide from me a master of Senjutsu and Youjutsu" he said shocking Issei. He was being praised by someone legendary and he managed to hide his aura from a master of senjutsu.
"Thank you Sir Sun Wukong and I am Issei Modi Thorson, one of the sons of Thor and also the Red Dragon Emperor," He said bringing out a gauntlet to show for a second before he brought it back.
Suddenly from The first monkey king's pocket, his phone started to beep. He took it out to check and sighed looking at it." Sorry, I would love to talk further but work calls" he activated a transport circle and said, " see you soon".
"I think we must be on our way dad I miss everyone and I am tired," issei said
trying to hide his yawn.
"Then let's activate the Bifrost"He summoned Mjoylir and started to channel
some of his divine aura into it. suddenly a rainbow beam of light shot from
the sky on them teleporting them back to Asgard.
(Asgard, Bifrost building)
Odin, Frigg along with Sif and her 2 children were waiting for the rest of their family to return. Sif, on the other hand, was having a metal Harrison on her hand ready, She was anxious as while it has been only three days for them, issei has been away for three years as time runs differently in Naraka. She was also waiting to beat her husband to a pulp if issei arrived all tired and near dead like how magni came back. while Thor is one of the strongest Gods to live he is a little puppy in front of his wife so she can happily reprimand her husband if he is too reckless.
Suddenly th gates of Bifrost opened revealing issei and Thor who was back.
"Issei how are you, my baby, Did this madman push you too hard," She said throwing her Harrison away hugging her first son tightly
As she hugged, she felt Issei's body started to bend down . She slowly released issei from the hug. His face was completely red and in the background.Thor was laughing hard.
"You Did it not me," Thor said snickering at his wife who simply huffed in response.
"So issei how strong are you now i wanna fight you "magni said much to Sif's annoyance.
"I wouldn't say that if i were you magni and if you really wanna know then wait for tomorrow everything will be cleared tomorrow ."Thor said with a smirk.
" Wait are you telling me that issei "Sif said and thor nodded All the elders were happy except for magni and issei  who didn't know what's going to happen tomorrow.
" So ise tell me did he push to too hard "Sif said because she knew if what thor told him happened then it would have been hell for issei .
{Lady Sif Thor did push issei too hard to the point where he nearly died every single day. Thankfully he has phoenix healing or else he would have died at day one}Draig said bringing out the boosted gear signing thor's Death certificate.
Suddenly the surroundings started to shake as Sif started to release her aura and Killing intent at her husband who was sweating bullets.
"So my dear husband what do have to say for this," She said passing issei to Magni and Thrud, cracking her knuckles walking towards her Husband.Thor started to shiver in fear and he silently cursed the red dragon who materialised popcorn inside the boosted gear getting ready to watch theshow.That night the whole of the 136th floor was soundproofed and put in lockdown for the Greater Good.That night was complete hell for Thor.
(Mid night issei's mindscape)
" So What's gonna happen tonight "asked confused issei .
"First of All congratulations partner  you reached the heights of top 10 strongest beings in the world so it will be going to be official at anytime right now .Thats what your father was saying . So which name are you going to use . issei hyuodou or Issei modi Thorson . Great red will give you a title according to the best of  your abilities." Said Draig
"I'll go with my current name draig I don't wanna use my previous one "issei said while sighing suddenly everything went black .
When issei woke up he was not in his mindscape but he was in a forest . The forest was so much beautiful. He was currently standing on a path so he decided to go and see where it leads.
After some time he arrived at a place which he can definitely call the most place he has ever seen. There was a beautiful waterfall Infront of him and the landscape was so much beautiful . There was a villa just beneath the waterfall . He saw three beautiful womens there so he decided to go and ask them where he was .
"Excuse me can you tell me where i am and how i got here " issei said with a confused expression on his face .
Women 1 : first of all you are in the tree yggdrasil and we called you here allow me to introduce myself im present.  the women on my left is past and on right is future. "the women said to issei .
" Why you have called me here "said issei calmly "we called you here because of your ritual that you are going to take and before you ask let me explain. This ritual is same which the other strongest being like Great Red and ophis along with all the others which are in top 10 take . You have reached the ranks of top 10 strongest beings and thats why we called you here . So issei modi Thorson are you ready to take the ritual and represent your name in top 10 strongest beings in existence. " Future said and issei just nodded .
"We want you to answer one question for us " past said "what are you going to do with your powers "
"I just wanted to protect the ones i love and kill those who try to take them away from me " he said and they smiled at  this .
"Now then thats clear i want you to summon your divine axe . We will channel a bit of our aura in it and you will get  your divine weapon's potential unlocked " future said and issei nodded then they told him to go to the waterfall and take a bath in that water after that they said " you have a major role in coming war so you must be prepared because you might lose your loved ones in the coming war .We will tell you about war next time because this is not the only time we will see each other .Now for the title because you have the same power as shiva God of destruction. We hereby gave you " Issei modi Thorson Son of God of Thunder and Goddess Sif Grand son of Odin and freig The possessor of Boosted Gear a.k.a Red dragon Emperor. Rival of shiva hindu destroyer, we gave you the title of  'Thunder God of anailation and destruction '.
Issei felt a wild serge of power flowing through his body. He was feeling like he can destroy anything in the world and take on anyone he pleases .
" You can leave now but we will call you once we wanna talk to you . "The three fairies said and issei returned to his dreams .
They then completed the ritual by registering his name in Top 10 and at that moment his power spread like wild fire at every corner of world .
(In Mount Kailash)
Pravati , shiva indra sun wokung and all others were now gathered at mount Kailash because shiva gathered them to see this show . Suddenly when they felt such amount of power their faces become paler .
" Issei you truly are worthy of such title i will see you soon "shiva said with a blood thirsty grin on his face. He can't wait to face his rival. 
(In Mount Olympics)
Ra and others were doing some paper work while ra was cursing his luck because he had a spar today but his wife didn't allowed him to go because of paper work . When he felt such power he sighed and said .
" Hmm it seems your son has reached the rank of top 3 strongest beings .im definitely going to contact them tomorrow and congratulate them . They all said in Union.
( Heaven )
An angel with blonde hair and emeralds eyes was doing his work when he felt this much power his face become pale .
"So it seem issei has reached that height huh " Michael said with a smirk . He knows his magic signature after all he has biblical gods system.
(Underworld)
Sirzechs,Ajuka serafall and felbium were currently now in a meeting when they felt this much power .
"I hope we do not offend him or it will be the end for all of us ."Sirzechs said with a sigh . " We already have alot on our plate so we don't want anything else . Issei modi Thorson I'll definitely meet you soon . " Sirzechs said and they all nodded .
( Grigori )
"So it seems that your kid has finally reached that height huh. Issei I'll definitely come to visit you and ask for my forgiveness. "azazel said with a smirk he knew who's this power signature belongs . After saying this he continued his work .
( With vali )
{ It seems Thor's son has alot of potential huh . But it feels familiar } albion said to vali completely confused. She just nodded and continued her mission .
( Shinto faction )
Susuno was sitting on his throne with Artemis on his side and Armaterasu sun Godess standing Infront of him . When they felt issei's aura . Susuno sighed while Armaterasu had a grin on his face .
"I'll definitely make you mine son of Thor " she said while licking his lips . The same can be said for Artemis.
(Meanwhile in Asgard)
(Before issei's display of power )
Odin , Thor ,Sif ,Freig and all other members of family were talking to each other about issei's development and his future . When they were talking about this they saw a massive grin on Thor's face .
"Father can you tell me why you are in such a good mood today and what do you mean by that what you said earlier " magni said completely confused.
"Magni your brother Issei has reached the ranks of top 10 strongest beings in the world and he is currently doing his ritual now . That's the reason im happy and you will see how strong he is when his ritual will complete. So for now let's wait . You will go through the same ritual when you will be 20 years old  " Thor said with a smirk.
" So you mean he got that far ahead from me and Thrud "magni said completely surprised.
"So how strong is he . "Thrud said completely annoyed because his younger brother surpassed her in three years.
" You will see in some moments " thor said much to everyone's annoyance.
When issei's aura spread across the whole planet .They got surprised they do not have words to explain what they were feeling.
"So he's tied with shiva bhama and vinshu in top 3 strongest beings huh " loki said and thor nodded.
"This is his power which he got from us and with his boosted gear. He can go head to head with beast class and dragon God class beings ."Thor said dropping another bomb on them .
"So its save to say that he's a monster if provoked he is completely ruthless if you call me battle maniac then see Issei he will break you into pieces before you move can even move  a single muscle and magni shiva said you can also reach the same heights as your brother but because he has boosted gear he will always be ahead of you so don't get discouraged. Shiva said this to me when we both were training him " Thor said they were sweating bullets when thor told them what a monster issei is but got surprised when they heard that magni has same potential as issei much to thrud 's annoyance. Because not only her one brother but other younger brother too will surpass her one day. But she was happy because she knew that both of them will not harm anyone.
"Now then that's out of the way we have to take some preparations for the party ". Odin said and they all nodded .
