The 22-year-old has penned a three-year deal with Paul Lambert's side and becomes the club's fifth acquisition this summer.
Luna made four appearances for Sevilla last season before being sent on loan to Mallorca for the remainder of the campaign.
"I've always believed that I could play in the Premier League and to have this opportunity with a club as historic and huge as Aston Villa and with a manager who is building a squad of young players with great prospects is tremendously exciting for me," Luna told the club's official website.
"I really can't wait to get started and to play my first game. I have a great expectation coming here.
"The manager explained to me that it is a young squad but also one with good experience and everyone is hungry, everybody wants to succeed here. This is perfect because I am keen to make progress myself and I want to be part of this.
"My background will help me and I will use all this experience to help the team. I know the mentality here and we will all work hard as players, we will all work together to push Aston Villa to the highest level possible."
Luna insists he is ready to adapt to the Pace of the Premier League and claims his experience in La Liga should ease his transition at Villa Park.
"Obviously, I have watched Premier League games and I am totally aware of the pace of the game and that the challenge is to constantly be at the maximum and top of your performance," Luna said.
"There have been many good and great players from Spain who have come here and succeeded and I know I can adapt my game also. The quality of football in La Liga is also respected everywhere and this is why I believe I can do well in the Premier League."
