After Issei was promoted to High-Class Devil, he was given the right to receive his own Evil Pieces in the events of Volume 22. He trades some of his unused pieces with Rias for Asia, Xenovia and Rossweisse, and with Lady Phenex for Ravel.
For the International Rating Game tournament, Issei formed the team: "Team Red Dragon Emperor of the Blazing Truth", as he had members of his peerage take up roles in he team as well as added Irina, Bova Tannin and Grayfia Lucifuge to fill the role of his Knight, his Pawn and his Queen respectively. Elmenhilde also makes an offer to join his team. Ouryuu Nakiri and Elmenhilde would later fill their roles as Pawns, and Bova became a Rook while Roygun Belphegor served as their advisor and later joined the team as well.
In True Volume 1, Issei reincarnates the last descendant of the original Leviathan, Ingvild Levithan as his Queen.
In True Volume 4, Issei trades his remaining Knight Piece, to Sona Sitri in exchange for Bennia Orcus, making her his second Knight.

Issei Hyoudou CompanyEdit
The Issei Hyoudou Company is a branch business of the Gremory Large Enterprise and serves as the main base of operations for Issei's peerage. As it is a place specifically for Issei and his peerage, it is its own business a part of the enterprise run by Issei as the company's president, with Ravel serving as its vice-president. This makes Issei a branch manager of the enterprise at the same time. The workplace was originally one of Azazel's labs he had set up in Kuoh Town and is used for Issei and his peerage to do Devil jobs. It is located in a basement under a private cram school ten minutes away from the Hyoudou Residence; the school had been bought by Grigori who built the basement where Issei's company is and then it was transferred to Issei. Access to the company is done by travel via elevators in the cram school where only relevant personnel can proceed to the basement, due to special recognition systems in the elevators.
The workplace is small where there is a single long corridor with one door directly in front at the end, three on the right, and two on the left totalling six rooms altogether. The rooms on the right side starting from the one closest to the elevator is the shower room, followed by the male and female toilets. On the left side starting from the elevator is the storage room, followed by the lounge which is equipped with a kitchenette. The door at the end is the office with a placed sign that reads: Issei Hyoudou Household Office. The room is quite spacious and its size is fifty square metres large. There are several desks inside, on top of which are documents and computers, while file cabinets stand on the side along with a fax machine and a sofa for guests. There is a space for a magic circle which is used when performing Devil jobs.
The requests for healing are given to Asia, those for physical activity are given to Xenovia, and the requests requiring magic are given to Rossweisse. Ravel is the bookkeeper but occasionally will respond to requests and Issei responds to the same clients he has had since becoming a Devil.
