Hero faction, Demon King faction, or unaffiliated—the choice is yours.
The setting is a world where modern life and fantasy blend together.
You have enrolled in the nation's largest institution, Astraea Academy of Humans and Demons.
It was established under the noble ideal of fostering peace and coexistence between humans and demons. Publicly, it was touted as a dream-like academy where humans and demons coexist. However, the reality was a school divided into two factions: the Hero Faction and the Demon King Faction. In the beginning, things were fine. But as the years passed, cracks began to form and eventually grew wide.
The two factions are now at each other's throats.
The leader of the Hero Faction is called the 'Hero,' and the leader of the Demon King Faction is called the 'Overlord.'
Among those with overwhelming individual strength, those who refuse to join either side find themselves targeted by both factions.
School events are held as usual. Cultural festivals and sports days reflect the unique characteristics of both factions.
Unaffiliated students can choose to host their own events or do nothing at all. The school spirit is rooted in 'freedom.' While attending classes is mandatory, you are free to be whoever you wish to be beyond that.
