Author's Note: This is my third DxD fanfiction and my second attempt at making a crossover. Being a longtime To Love-Ru reader, I really feel that Rito needs someone like Issei to become a better man. Despite Rito making marginal improvements starting in To Love-Ru Darkness, he still has a long way to go.

The story will start in DxD world and quickly shift to To Love-Ru world. The story will mostly focus on the To Love-Ru with Issei being pretty much the only element from DxD.

Like Boku wa Tomodachi, this fanfiction is completely separate from my other To Love-Ru and High School DxD fanfictions.

Chapter 1:

Introduction – Devil Graduation

Today is the day of the ceremony. Everyone is seated in their proper positions, waiting for the announcement from Sirzechs Lucifer, one of the four Satans that govern the entire Underworld. By the time Sirzechs arrives to the podium, he is greeted with applause.

"Greetings, everyone. I have brought you all here to celebrate the inauguration of our new high-class devils. Ever since the Great War many centuries ago, our devil population has shrunk to a small fraction. We have been making every effort to preserve and grow our devil population back to its original size such as our alliance with the angels and the fallen angels who were once our greatest enemies. Because we devils have a very low birthrate, we have been seeking alternative methods to raise our devil population. Thanks to our Ajuka Beelzebub, his invention of the peerage system has allowed us to reincarnate highly qualified creatures including humans to become devils. Once these reincarnates demonstrate their strengths, powers, techniques, and intellects being on par with us pure-blood devils, we shall accept these reincarnates into our devil society."

Sirzechs then continues. "Becoming a high-class devil was not an easy task for these reincarnates. These devils have endured constant hardships, troubles, and discrimination from us pure-blood devils. Hardships include abuses from their master, intense training, intense surgery, and near-death fights. However, these reincarnates sitting in front of me have demonstrated themselves worthy of holding the title 'high-class devil' and we shall now treat them as equal as pure-blood devils. I will now hand the podium over to Ajuka Beelzebub, who will also present each new high-class devil their evil pieces."

The audience gives applause to Sirzechs as he steps down. Ajuka Beelzebub, also a Satan, walks over to the podium and gives his speech.

"Ladies and Gentlemen, my servants are currently preparing to hand over each new high-class devil a set of their own evil pieces. By taking this important step, we can further expand the population of us devils. Each newly graduated high-class devil will become a king of their own peerage group and be given a set of 15 pieces. We wish these high-class devils will choose their new peerage wisely and contribute to the strengths, powers, techniques, and intellects of our society, allowing us to protect ourselves more effectively in the case of another Great War. We also hope to see new challengers for our rating game."

The rating game is an event where high-class devils get to challenge other high-class devils with their peerage. Under different game rules, the high-class devils must understand the abilities of each of their peerage members to maximize their advantages and increase their chances of winning the game.

Ajuka's servant roll a large cart filled with many wooden boxes. Each box consists of 15 evil pieces.

"Now that the stage is set, it is now time to officially graduate these middle-class devils into high-class devils by giving them their evil pieces. Please form a line to the right."

All of the new high-class devils line up, waiting to receive their wooden box. From Rias's group, Issei, Akeno, and Kiba are in line. No one from Sona's group is in line as her peerage group including Saji is still working towards the middle-class devil rank.

Kiba is next to get his box. Sirzechs hands Kiba his wooden box. Kiba takes a glance at the evil pieces inside his wooden box before stepping off the stage. As he walks off the stage, most of the women in the audience quickly ask Kiba to make them his servant. Kiba declines them all as he returns to his seat.

Akeno is next to get her box. She gratefully takes the wooden box from Sirzechs and walks back to her seat. Like Kiba, she gets bombarded by men who request to make them her servant. Akeno declines and also tells them that qualifications for her peerage are too high for them.

Issei is next to walk onto stage. Sirzechs introduces Issei a wooden box. Issei glances at his pieces and returns to his seat. Like Kiba and Akeno, Issei gets the attention of young children. Most of these children are fans of Issei's 'Chichiryuutei Oppai Dragon' TV show. Despite these children being born as pure-blood devils, they make their request anyways.

After a few more new high-class devils receive their boxes of evil pieces, the graduation ceremony officially ends. The entire Occult Research Club returns to the old schoolhouse building at Kuou Academy. Issei is smiling as he looks at his shiny new evil pieces.

"I did it. I'm now a high-class devil. From today, I will make my ultimate dream come true. I will build an all-female peerage group and create my own harem. Woo! I can't wait to get started."

"Congratulations Issei, I am proud of your work. I wish you the best success Issei. Akeno and Kiba too," Rias makes her compliment. "Everyone else, I hope all of you will show outstanding results like these three new high-class devils here. There is still plenty of room left for additional high-class devils in our society."

"Yes, Buchou. We'll work hard." The promotion gives encouragement to Koneko, Asia, Xenovia, Gasper, and Rossweisse, all who are still low-class devils. Xenovia and Koneko have an endorsement pending while Gasper and Rossweisse are far from promotion. As for Asia, her abilities make it difficult for her to get endorsements for promotion. However, she still smiles and supports her group.

"Do your best, Issei-san, Kiba-san, and Akeno-san."

"So, any plans from you Akeno and Kiba? Do you have any idea who you want to add in your peerage group?" Rias asks.

"Well, Buchou, I haven't thought about my plans yet. It already feels strange to be a king for you own group. I really don't know who I will end up adding." Akeno is first to answer.

"Same here, I haven't really thought about my plans yet either. Unlike Issei-kun, I never really had close friends and contact with normal humans," Kiba answers.

"That's OK, Akeno and Kiba," Rias replies. "When I got my evil pieces from my father back in junior high, I didn't know who I was going to add to my peerage group other than you Akeno. I guess the surprise is part of what makes this exciting," Rias smiles at Akeno.

"Yeah Buchou. When my peerage group is all built up, I'll have a rating game with Issei-kun. Uhuhu, Issei, it will be fun to compete against your peerage of females. It will be fun," says Akeno.

"Yeah, I want a rating game with Issei-kun too. We can use the results to motivate us to work hard, even as high-class devils," Kiba brings up a suggestion.

"Do you best Akeno, Issei, and Kiba. I look forward to meeting your new peerage members and seeing your rating game results," Rias congratulates all three of them.

"Reality hurts. Maybe I am better off staying as a middle-class devil," Issei cries upon hearing Rias's message.
