|Anime Debut||Episode 20|
As a defensive midfielder, Hiraga has a wide area of defensive coverage. He also usually possesses enough stamina to last through an entire game. As the captain, he carries the Osaka Gunners onto the field and thus is usually never switched out during the game.
Being the captain Hiraga is a little more level headed than most of his teammates but still can be a dork. He prefers loud players and thinks Kubota is boring but doesn't doubt his skills.
During the game against ETU, Hiraga was forced to go up against the fast Daisuke Tsubaki several times by Gino's deceptively inaccurate passes. After being forced to run throughout the game, his stamina was shot by the last 20 minutes of the game. However, he was not switched out immediately because of Coach Dulfer's philosophy of maintaining a consistent and successful strategy regardless of the opponent's strengths/weaknesses. This resulted to giving ETU the entire midfield which Hiraga would usually cover.  Eventually, he is switched out after ETU's second goal.
- The surname Hiraga means "flat, broad, level, even, peaceful" (平) (hira) and "congratulations, joy" (賀) (ga).
