In a master bedroom, a young man was asleep, dreaming about playing for the biggest and greatest audiences. Playing for kings and queens and fans of every shape and sizes, and they were screaming his name. But, like with all dreams, it was broken by a loud noise, his phone. He reached over to answer it. "Yeah?" He heard a very soft and sexy voice on the other end and the three words she said woke him up.

"I need you."

"Okay," he stretched. "I'm on the way." So he got up went to his bathroom to wash up, he got dressed and grabbed a guitar case.

Meanwhile, Rias Gremory was fighting for her freedom not to marry Riser Phenix, he had her pawn, Issei, pinned and was about to kill him when all of the sudden. There was music playing (picture a heavy metal version of the 'Halo 1' theme), it came from a guitar. Everyone were looking to see where the music was coming from and saw a young man. He was dressed in a vest, leather pants, boots and a horned cowboy hat. He was carrying a guitar case and was riding a musical scale. He landed in front of Issei and stood up, "hello Riser." He said coldly, Riser gulped.

"Blue-Bluegrass," said Riser. That was the man's name, Bluegrass Gremory, an adopted member of the Gremory clan. Reborn fallen god of music and Rias mother's 'Queen'. He was a very dominant piece and that was before her father made him Rias other knight, rook and bishop.

"Then you know what's about to happen next right?" Said Bluegrass, "you are better off surrendering." Riser was insulted.

"I DON'T CARE WHO YOU ARE, RIAS IS MINE!" With that he attacked, the 'Rock and Roll Cowboy' just sighed.

"He never listens." He said sadly, he pulled out his guitar (picture Gene Simmons guitar but it was a lead guitar and had blood on the blade). He pointed the top of it at Riser and started to play. (the guitar solo from 'One' by Metallica) The music knocked the Phenix back into walls and through his own peerage. "Want An Encore? Or Are You Going To Give Up?" Riser slowly got up, spat out some blood and glared at him.

"Nev-NEVER!" He screamed at Bluegrass, "YOU SHOULD SURRENDER! DO YOU KNOW WHO YOU ARE FACI…?" Tired of his mouth, Bluegrass punched him in it, breaking his jaw and knocking him out.

"I do believe that's 'Checkmate'." He said and with that the battle was over and her walked off the field after grabbed his guitar case. Once off, he walked right to Rias who had her head down. He lifted her head so she could look him in eyes. Then she grabbed him in a tight hug, her head against his chest. Issei was freaking out.

"Who is that?" He asked.

"Ara, his name is Bluegrass," said Akeno. "He is Buncho's ultimate piece."

"He has the powers of a Queen, Knight, Bishop and Rook all rolled into one." Said Kiba.

"But… no one's THAT powerful!" Said Issei, Rias pulled off of him and held him at arm's length.

"He was my mother's 'Queen'." She said, "he also volunteered to be my other knight, rook and bishop. He's the reason why I have only one of each."

"I promised on her mother's deathbed I'd take care of her. Since Sirzechs was being primed to be the next Satan and couldn't watch over her. So just call me a mix of a Caretaker, Elder brother and Lover." With that he kissed her on the forehead. "I Know You're Watching 'Zechs! Come On Out!" Just then a couple appeared in a flash of light, the man was in a suit and the woman was a maid, the man had long blood red hair and deep blue eyes, the woman had long silver hair and silver eyes.

"Bluegrass-tan," he said as he went over to him and hugged him. "A wonderful performance as usual." Bluegrass just looked at his 'younger' brother and chuckled, then hugged him back. Then the woman had went over to him and hugged him as well. "For your reward, you can have any wish. Whatever it is, I'll grant it." Then he snapped his fingers, "I almost forgot; I'd like you to perform for my party this weekend."

"A little short notice isn't it?"

"Well you know how I am sometimes." Bluegrass and Rias sweatdropped.

"Alright I'll play, oh by the way, my wish is Rias' hand in marriage." Everyone was in shock.

"Wha-What?" Said Issei, Bluegrass looked at him.

"Listen, Issei right?" He nodded, "dude I can smell the lust coming from you. She's not a trophy to be won and shown off and that's what Riser was going to do."

"But…"

"They are not my siblings, I was adopted into the Gremory clan by their mother."

"Issei, Bluegrass was going to marry Rias anyway until mother had died." Said Sirzechs.

"I see," said Issei sadly.

"Don't worry kid, I need you to do me a favor. She is a handful, could you keep an eye on her for me?" Issei nodded and Bluegrass started to walk away as a portal of light was opened. "I'll be back," Rias stopped him before he left.

"Blue, where are you going?" He smiled at her and went in. With that the portal closed and he was gone. "Sirzechs, where did he go?"

"There are a few things Grass needs to take care of, he'll be back." He said, "now come I'm sure you must be starving." So they teleported to Gremory Manor.

Meanwhile, Bluegrass had appeared in the main room of a huge house and kicked off his boots. Just then a servant had appeared she was dressed like a maid but had a cat's tail in the back. "Welcome home Bluegrass-sama." She said.

"Thanks Bakeneko," he said. The maid had long black hair and green slitted eyes. She curled up on him and started to purr.
