Author's Note: As mentioned a couple of times, I was planning on starting a second fanfiction from High School DxD titled "Issei's Dream World". That idea standalone wasn't going to work. In this version, I combined the story with "The Gremory Gala", which was another DxD idea that I scrapped a while ago.

The story will start with "The Gremory Gala" and will alternate between "Issei's Dream World". While Issei is stuck in another dimension, the others will be stuck working at the casino.

As of writing this chapter, I just started Volume 15 of the Light Novels so expect inaccuracies. I planned to start this fanfiction at the end of Volume 12, but I guess more volumes help.

Chapter 1:

Introduction – Rossweisseville

"It is a pleasant morning to welcome everyone to Rossweisseville. Thanks to a generous contribution and support from Rias Gremory and Sona Sitri, I am able to open and dedicate this town to everyone who lives or visits the Asgard countryside. By opening this town, we can modernize our countryside to match the rest of the world. This town is filled with many modern facilities that will prove to useful to everyone. From the 100-yen shop hall to the Great Academy of Magic, there is always something here to fit everyone's interest. Thank you."

Rossweisse is standing in front of the podium making her announcement. To the left of her is Rias, the president of the Occult Research Club and to the right of her is Sona, the Student Council President. The group of three is currently standing in front of a freshly-constructed town named 'Rossweisseville'. The town is named to commemorate Rossweisse's wish. Before Rossweisse became a staff member at Kuoh Academy and a member of the Occult Research Club, she was a poor servant for Odin, one of the Norse Gods. After experiencing the life of Japan and seeing all the benefits she has missed out, Rossweisse has dreams of wanting to bring such experience back home. During the Occult Research Club's latest adventure to discover Rossweisse's birthplace, they found an abandoned village. Given that most of the buildings are in good condition, it was not going to be too difficult to rehabilitate the entire village. Therefore, both the Gremory and Stiri provided Rossweisse some assistance to bring the village. They let Rossweisse plan out most of the details for the new town. Overall, the entire rehabilitation project took only 6 months of work thanks to the males in both Rias and Sona's group which included Issei, Kiba, Gasper, and Saji.

Rossweisse finishes her speech and steps down, led by applause. Next, Sona steps up and makes her introductory speech.

"Thank you everyone. I am proud of Rossweisse's efforts of being a Civics instructor at Kuoh Academy back in Japan, the academy that my Sitri clan has part ownership of. I am also grateful to partly contribute to this project. My goal has always been to build a fair and unbiased education institution. Along with Rossweisse's Great Academy of Magic, I will also open and dedicate the Tactics Institute here. This institute will train devils, angels, and other mythical creatures. Unlike many current schools where entry-level students and beginners are frowned upon by their seniors, discrimination in school is outlawed. As the top student graduating from Kuoh Academy, you can be assured that I will provide one of the finest lessons in the world. On a final note, I encourage everyone to apply and enroll at my institution."

Everyone gives applause as Sona steps down. Rias gives her opening speech as well.

"Hello everyone. I am proud to have Rossweisse in my peerage group and to be able to provide this level of contribution to her. It has always been Rossweisse's dream to open up this town in Asgard. As part of my contribution, I will also open a venue of mine here in Rossweisseville. The venue, called The Gremory Gala is a full-service resort which includes a large casino, recreational facilities, lodging, and many choices of fine dining. Since my peerage group has become popular, this resort will also have a special event for a limited period where you can get to meet the members of my peerage group. Whether you are tired from your training or your endeavors, The Gremory Gala is a great place to rejuvenate your stresses. Please come and stay at The Gremory Gala."

Rias's message gives excitement among the audience. Many men want to take photos and get autographs from Akeno. Many women want to take photos and get autographs from Kiba. Koneko and Asia are also popular as well. As Rias steps off the podium, instead of applause, the audience chants Rias's name repeatedly.

"Rias… Rias… Rias… Rias…"

With Rias and Sona having given their opening announcements, Rossweisse officially opens the town to everyone in the audience. Everyone quickly races into the town and begins to explore all of the places in this small town. In a matter of seconds, the entire 100-yen shop hall is packed with shoppers. Shoppers are tossing items and shelves are emptying quickly.

The only people that stayed behind are members of Occult Research Club and the Student Council of the Kuoh Academy. Issei fell asleep through the dedication ceremony. He was assigned most of the tedious work in the construction of Rossweisseville. Now, Issei is out of energy and is unable to stay awake for the opening speech. Asia is busy wiping off the drool from Issei's mouth while everyone else looks at Issei's cute sleeping pose.

"Issei-san, you're so spoiled," Asia smiles.

"Issei-senpai looks tired. Let me restore his stamina by getting his ki moving," Koneko offers to help.

"No, it is my responsibility as Issei's manager to recover him," Ravel fights with Koneko.

Akeno and Kiba also want to accompany Issei while he is asleep, but they get blocked in by other people. Akeno is popular among many males and Kiba is popular among many females. These people plan to get photo shoots with Akeno and Kiba at The Gremory Gala and spotted them. They want to get the photo shoot on the spot so they won't have to wait in line. Before Akeno and Kiba can properly greet everyone, questions about their appearances and reservations for the photo shoot are flowing in so quickly.

"Ara, Ara, I'm too popular what should I do?"

"Alright, calm down girls. I will accept all of your requests."

Saji also had to do most of the heavy construction work. He is also getting his share of therapy from other members of the Student Council. Unlike Issei, Saji is able to stay awake for the entire dedication speech. Since he is the only male in the Student Council, he is used to handling all of the grunt work. As the opening speech comes to a close, Sona walks over to Saji and gets him to work again.

"Saji, the meeting is over. It's time for you to clean up the stand."

"Yes, I'm on it." Saji quickly takes down the decorations and puts away the podium.

As the Student Council gets to work in cleaning up, Rias walk over to the Occult Research Club. Since it is currently Grand Opening for The Gremory Gala, she wants everyone to work at the resort to promote its image and attract newcomers. The club is filled many popular people and the club has made many achievements such as taking down different factions of the Chaos Brigade.

"Alright, let's get started everyone. Let's assign tasks for everyone."
