RPG Insanity

Where is it?

where is the hidden arena? downstairs in the upper left corner of the arena

Thanks

is the secret arena still accessible post game (after completing happy ending)? I honestly forget the location of the Arena during the normal ending, i remember it around the  guild but i can't seem to locate it again after completing the happy ending.

Like the normal arena, the secret arena is located on the Glorious (left side, lower stairs, then stairs in upper left corner), the ship you first gain access to in Dragonia City over the course of the story. Depending on where you docked the ship, you can find it either in Dragonia City or at the northern edge of the Kinari (eastern) continent (on the world map) north of Kira.
