Where better to go?

There were enough things in the A-Zone to keep the Phantom interested and entertained for the remainder of his imprisonment.

The rules worked the same for everyone, so those who could get to the A-Zone, that is - defeat Krana and Trana, their sentence reduced to 20% of their original length.

However, that wasn't entirely true.

If Phantom behaved well and didn't cause any problems to Guardians or other prisoners, he could appeal for a reduction in his already greatly reduced sentence.

For example - Adam had only 35 days left to go out of the original 180. However, he would have no problem getting out in three weeks, or at most 25 days. 

However, this was not the limit.

The A-Zone was the final zone for most Phantoms, but it wasn't actually that.

The final zone was the S-Zone - the black gate Adam was looking at.

"S-Zone... If I get there I get my freedom, right?" Adam asked, with a mesmerized stare.
