Arena

The arena is a part of the Demon King Academy.

History
The arena was originally a place where people fought to prove their skills. Later when the Demon King Castle was turned 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 in order to pass.

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

Description
The arena is split into various sections, lettered from A-G since Anos mentioned 7 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.
