Hagun Academy is one of the seven knight academies located in Japan, spanning an area said to be more than ten times that of Tokyo Dome. Unlike many other academies, Hagun has no intuition fees or other kinds of expenses that the students need to pay, making it ideal for poor students. However, Hagun is also stricter on taking in students, as new students require at least a general level of abilities and capability.
Compared to the other six academies, Hagun Academy hasn't produced any strong assets in the past years and is on a losing streak in the Seven Stars Sword Art Festival, a competition sponsored once a year by the seven schools to select the strongest apprentice knight. However, this has recently changed, with two Hagun students, Ikki Kurogane and Stella Vermillion, making it to the finals of the most recent Festival, which Ikki won.
- Battle Arenas: For training purposes, Hagun Academy is equipped with several dome-shaped arenas dotted around Hagun Academy's campus. The interior of each dome included a space for combat with a roughly hundred-meter diameter, with audience seats built on a bowl shape around that space.
