Welcome to Hachiman's Arena! Well, it is actually a barren field with low growing plants. It is behind a set of big double wooden doors behind the camp. This is where demigods practice large-scale battles. They also hold events here.
Events will be given once a month but sometimes does not so be on the lookout for announcements.
Users may sign up their characters in sign-up pages which will be posted a week before the event. But some events have requirements so read them carefully to know if your characters is eligible to join.
Admins are the only ones who can make an event. If you have ideas for an event, go the the suggestions forum.
