The Frontier

Demon capital

The Frontier is the largest city of the Demon Realm and its new capital in Volume II. A long main road leads toward the Demon Castle; ordinary work stops when the city recognizes the captive Lord of the Tower. Its public life is shown through fear, surveillance, and the authority of the demon crown rather than through later accounts of prosperity.

Shun’s return

Shun is brought through the Frontier after the Hikari intervention to answer to Magnus. Zero and Roku wait by the portal while the city and castle become the route into his punishment.

City of the demon crown

The Frontier is presented through Shun’s coerced passage: its main thoroughfare gives the city a single oppressive axis running from the portal district toward the Demon Castle. People interrupt their work to watch the fallen Lord pass, and their reaction makes his former reputation visible even in defeat. Its streets are therefore not merely a backdrop; they are the public corridor through which the Court turns punishment into spectacle.

Connected institutions

The castle and the Portal Cathedral serve different functions. The castle contains the dungeons and court that judge Shun. The cathedral, marked by four power-radiating pillars, is the route through which a broken Shun must return when Magnus withdraws the easier use of his shadow travel. Together they make the capital the infrastructural centre of demon authority in Volume II.
