Chapter 1

Here it is the Seven Deadly Sins and DXD crossover. I'll be using the anime and manga to stay in line of the plot so I don't screw it up. Also, Issei will receive Gowthers power but that will be later in the story. Also, like Rimuru has Ragna, Issei will have Fenrir. I always thought Issei could have a better familiar than the boat he got as a gift. Fenrir could help be support and actually fight with his fangs and claws.

The pairings in the anime of the SDS will be the same but Issei's harem will have six girls. I decided to add Jericho as one of them, so give me some ideas who should be with him or if I should make an OC for him.

Also Issei won't be OP but with his power from the Loki Arc, he is stronger than Gilthunder and Howzer without the Balance Breaker. Against demons, I'd say he's on par with Galand in his Balance Breaker.

So without further ado, let the story begin.

Issei used his boosted power to lift Mjolnir into the air and hit Loki with his all of his might. Before Loki disappeared into the portal, he glared at the dragon hybrid and noticed that Fenrir was almost dead 'Tch! Useless dog.' Loki quickly chanted a spell and a portal opened where Issei and Fenrir were, Rias and the others could only stare as Issei was being pulled into the portal with the God killing dog. Loki, seeing the events transpire laughed and said, "This portal will take the Red Dragon away from here and the only way for this spell to be cast is if the Dragon of Dreams and Ophis combined their power. I was fortunate to find the only copy of this spell in Valhalla where not even that useless Valkyrie would look. Now watch as your precious dragon vanishes. Hahahahaha haha! Farewell Issei Hyoudou!" The portal closes and Issei and Fenrir are gone to who knows where.

Issei woke up with a big headache and noticed two things. One, he was not back home or with his girls and two, he saw a certain dog on the grass, sleeping, while using his legs as a pillow for his head. Issei thought this was a regular dog rather than a god killer dog. He pat the dog on the head and it woke up nuzzling him. Ddraig was awake and checked on his partner. "Issei, are you alright?" 'Yes I'm fine but where are we?' The dragon shook his head "I don't know but it appears we're in another world. Oh by the way your probably wondering why Fenrir is acting friendly?" Issei nodded and Ddraig sighed and said.

"After the portal sucked us in, Fenrir grabbed us and gently placed us on its back. I noticed the Evil Pieces left you as we were traveling and must've gotten sent back home. Luckily, I was able to save you by making your body a hybrid of human and dragon. So now, your body is 85% dragon and 15% human. The new changes are that your new strength, speed, endurance, magic potential, and you also seemed to unlock a hidden power within you. Unfortunately, your body is more vulnerable to Dragon Slayers but you should be strong against Mid tiered dragon slayes. Fenrir has become close to you in the short time because of your kindness and wants to be your familiar. Do you accept?" Issei looked at the dog before him and decided to keep him "Alright. So how do I do this?" "Just place your hand on his head and pour your magic into Fenrir." Issei did as instructed and Fenrir accepted the pact.

Fenrir poofed in a thick of smoke and instead of a dog, a woman took 'his' place. Said woman was a tall girl with red hair that reached the back of her neck and her hair was in two braids that reached to her middle back. Issei and Ddraig were shocked until the girl looked at her master and said "Masterrrrr!" She glomped him and smothers his face in her new breasts. The 'terrifying' dog woman licked Issei's cheek like a dog, it tickles Issei until he noticed two things. One she's naked and two she has two dog ears on top of her head. He rubbed the ear and she liked it and whimpered like a dog who wants affection. Issei was brought out of his daydream by Ddraig and noticed that she needed clothes and fast.

Issei told the woman to stay and he left to find some clothes until he saw a carriage with a big hole on the side and noticed that the man inside was dead and so was his maid. He saw that the money was left behind and the clothes so bandits hadn't come yet. Despite going against his moral code, he grabbed the money and found some spare clothes that would make him seem like a common traveler and his partner as his maid/fellow adventurer. He went back and saw her waiting in the same spot as before. 'Looks like she is good with tricks.' He laughs a little and gave her the new clothes. She struggled a bit with the maid top so Issei helped her. She also had a cap on her head to cover her dog ears. "Master what do you think. Hehe!" Issei was finding it hard to believe that this was the god killer dog, then again he has met powerful people act like fools. Azazel and Sirzechs appeared in his mind.

Issei pat her on the head and said "I love it but why are you a girl? I thought you were a boy." She looked sad but explained "That dummy Loki didn't look at my gender. He just assumed I was a male because of my so called sons. Personally, I wanted to bite his head off but I couldn't because of the mind control placed on me. But after you beat me, I was able to think for myself and I am not saddened by Hati and Sköls death. They weren't my children just abominations created by that monster. I would like a new name. If you don't mind?" Issei saw the look in her eyes and thought of a name until it clicked "Lupis. Lupisregina. You won't be just my familiar. You will become my partner and I wouldn't mind trying to get to know you a little bit. If you don't mind that is?" Lupisregina jumped on top of him and kissed him while saying "Thank you! Thank you! Thank you!" Issei was picturing her tail wagging like crazy right now.

He picked her up and sat her down before taking out the map he got from the carriage. "Alright, according to this map we're in a world called Britannia and the main kingdoms are Liones and Camelot. From what I was able to find out from the journal that was in the carriage, there is magic here and people called Holy Knights. They defend the people with their powers and apparently there are only five races here: the giants, fairies, humans, angels, and demons. But the demons and the angels have been gone for a while and the giants and the fairies are in their own part of the country. It appears they aren't on friendly terms with human. So first things first, we need a base of operations and information on what's going on, luckily we're near a village with a tavern called the Boars Hat. I heard it from the villagers with my dragon hearing. So ready to roll?" Lupisregina nodded and said "Let's go Issei." Issei smiles at her happy nature and makes a note to get her a weapon in town.

Meliodas has seen many things in his lifetime but this certainly took the cake. He was serving his customers as usual with Hawk as the cleanup until the door opened and saw a man who looked 18 wearing a thin but durable set of red armor with a Sword that radiates holy energy at his side and a shield on his back. His companion was a girl wearing a maid outfit and had a scepter, that had a spike circlet, on her back. The two looked strong and thought they might've heard of his friends but the kid in armor made him suspicious. He seemed friendly so he approached them and took their orders. They made some small talk and some would say their dating which reminded him of a certain giant and fairy he knew. People were chatting around him about the Seven Deadly Sins and how one was spotted.

Suddenly, a being in rusted purple armor scared almost everyone, except for two, and they all ran out of the tavern leaving four people and a pig wondering who that knight was,m; they were shocked when they learned that the knight was a girl. Meliodas took her to the spare room while Issei asked if he could use the kitchen to make something for the girl. "You can cook?" Meliodas asked. Issei nodded "My mother taught me and Lupis can help out as well." "Mmhmm." Said Lupisregina.

Issei and Lupis were making a steak and a small salad for the girl. A few minutes later, Meliodas and Hawk came down with a white haired girl with blue eyes and her hair covering her right eye. Issei and Lupis introduces themselves and Meliodas said their new members of the Boars Hat. Meliodas put a finger up and grabbed them to speak to them. "Listen I could use some help in the kitchen. I'm a terrible cook and I could use your help. In exchange for food and board, tell me who you really are. I'm not a bad person nor am I a good guy. I'm just a normal guy running a tavern." Lupis looked at Issei "What do you think Issei?" Issei looks at Lupis and nods "Very well but if you betray us then your getting a beat down." Meliodas just smiles and nods in understanding.

They made some smal talk and Elizabeth spoke about her quest to find the Seven Deadly Sins so she can save her kingdom. Issei and Lupis were disgusted when they learned that the Holy Knights they were sworn to protect the kingdom and its people betray their own king. It reminded them of Khaos Brigade and the Hero Factions. The hero's claim that the supernatural shouldn't rule the earth and that the humans must reign. If Cao Cao were here, he'd be rolling in laughter at these knights and try to recruit them.

Unfortunately, a knock at the door came and voices were heard outside. "Attention, the Rusted Knight is here! Open the door or we will use force!" Elizabeth was worried but Issei told her to be quiet and whispered to Lupis "Use Complete Invisibility and get her out of here." Lupis nodded and Meliodas gave them a thumbs up for a solid plan. Hawk put on the helmet of the rusted armor and as the door opened Hawk came out and said "I am the feared Rusted Knight! Fear me!" The knights were furious and were about to draw their swords until a soldier outside said "Hey, two people are running out back!" The soldiers saw Lupis and Elizabeth run into the forest, then the soldiers chased after them. Hawk and Issei ran to them before Hawk knocked a guy off the cliff and Issei looked up to see Lupis in a tree with Elizabeth in her arms. Bridal carry style. Issei smirks and says "Lupis, I'm hurt. I thought you only had eyes for me. Leaving me for a woman, how cruel!" Lupis smiles and leaps down before placing Elizabeth on the ground and hugging him "I do love you, but I had to carry the princess. Forgive me?" Issei looks at her and says "For a kiss." Lupis closes her eyes and both of them close in on each other until the part of the cliff falls to the ground. Meliodas came down to help them.

Atop of the cliff was a burly man saying "Confirmed 5 unfortunate deaths." The knights were pleading with their boss until he threatened them by saying "Perhaps I should write down 9 unfortunate deaths instead. Any takers?" None spoke until Meliodas leaped out of the fallen cliffs side with Elizabeth and Hawk while Issei was flying with his dragon wings and Lupisregina was in his arms glaring at the man for interrupting their moment and for attacking them.

The knight glared at them "How dare you disrespect your deaths and leave without my permission." "No one asked for your permission!" Said Hawk. He looks at the girl with Meliodas and says "That earring, it bears the family crest of the royal family. That points out that your Princess Elizabeth of Liones." Everyone looks at her and says "Your a princess?!" "There's a reward for bringing you in Alive or Dead. So." He draws his sword. Issei and Lupis get ready to fight. "Conclusion. Accidental Death!!" The blade flowed white as it cut away the forest and Meliodas with Elizabeth were on the ground and both Issei and Lupisregina charged at the knights for attacking their friends. Lupis dealt with the knights while Issei faced Twigo.

Issei and the leader clashed blades, meanwhile Lupis made quick work of the knights. "Wow those guys were hardly a workout. I didn't even have a chance to use magic." She said with a pouty face. Issei smiles at her and says "Don't worry hopefully not everyone is as weak as these guys." A voice rang out "Hey Issei, Lupisregina step aside. I'll deal with him." Meliodas walked out with a serious expressions and both of them moved out of the way so they could get a good spot to watch the beat down. Meliodas just stood there and Twigo released his sword but after the attack he was cut instead. "Woah! Issei did you see that?" Issei had his dragon eyes out "I did. In the middle of the attack he used that broken blade to cut into the attack and send it right back at owner but with double the power. That must be his magical power." Lupis was amazed at the thorough examination then turned back to the fight and asked "What about that guy? The opponent. What's his power?" Meliodas chimes in "It allows him to extend the range of his attack to a certain distance. However, he has to pour his magic into a weapon in order for it to work." Twigo was shocked that his power was found out before looking at a Meliodas and said "Wait a minute, I recognize you now. But how could you look the same way you did 10 years ago?!" Meliodas readied his sword and swung it at Twigo, covering him in a white light and sent him flying into the sky. "This power...is that of the legend!" Meliodas's arm was extended and a dragon tattoo was on his arm "Leader of the Seven Deadly Sins. Meliodas, the Dragon sin of Wrath." Issei and Lupis walked to him and soon Elizabeth joined in the group. Meliodas looks at her and says "Well you found your first sin. I've been trying to find them because I have some business that involves them, so I'm ready to help." Issei chimed in "You can count us in." Both Meliodas and Elizabeth were suprised by this. "Why?" Issei said "Well we were seen with you and no doubt Twigo is still alive so he'll report Lupis and myself. So it's best we join you and besides you need a chef." Elizabeth and Lupisregina laughed at this while Meliodas poured and said "Not my fault."

A large green pig came out of the forest with the tavern on top of it and Hawk lowered the ladder "Come on you guys. Times a wasting!" They laugh before climbing aboard and Meliodas look back at Issei and say "I think it's time we have that talk about you two." Issei smiles and prepares drinks for them and sat down at the table. "Well it all started after I was killed by my ex girlfriend..."

First chapter up. So pm or leave a review about your opinion and I could use ideas for his harem. Also should Issei have the Gowthers powers and Sacred Treasure or should he inherit Escanors Powers and Sacred Treasure.

Next chapter will be the Forest of White Dreams. Introducing the Serpent Sin of Envy.
