Arena

The arena is a part of the Demon King Academy.

Description
The arena is split into various sections, lettered from A-G, since Anos mentioned seven lines when he was split up for the practical exam. The line leads to a waiting room, which connects to the inside of the arena through a long corridor.

History
The arena was originally a place where people fought to prove their skills. Later, when the Demon King Castle was repurposed into the Demon King Academy, the arena was used for the academy's practical exams, which consisted of having the examinees battle five opponents and win to pass.

The Demon Sword Tournament was held here, and anyone with tickets to the tournament was allowed to enter.

Waiting Rooms
Rooms where fighters stay before their matches begin. There is a magic mirror inside to let them spectate the other matches.
