This is a space like a coliseum, removed from everyday reality.

Guest has been summoned to this world for some reason and will face a series of battles against numerous powerful foes.

There is no need to think about a story here. The only goal is to fight and win.

The following laws seem to govern this space:

• You cannot leave the arena; doing so results in an automatic loss.

• The size of the arena adjusts appropriately based on the scale of destruction caused by those within. While cracks may form, the walls of the arena cannot be completely destroyed.

• Upon defeat, you are immediately expelled from the space. (Because of this law, lives are never taken, so you can unleash your full power without restraint.)

• Once you defeat a powerful enemy, your injuries are healed and all consumed resources are fully restored before the next battle.

• Generally, opponents of appropriate skill appear at random, but if you hold a specific desire in your heart for a certain type of enemy, there is a high probability that a matching opponent will appear.

• All these laws and rules are funneled directly into the minds of those who enter the space.

Good luck. ◠‿◠
