Isekai (Isla flotante)

When the character or system speaks, write the name of the person who is speaking followed by a colon and then mention what the character is saying at that moment.
For example:
System: User leveled up, level reached (10)

In this Prison there are no guards or anyone to control it, it only has a System to guide you, it is an island in the sky that contains a small water source, with infinite underground water channels.
There is no way out, since deep inside this island there is a layer of metal that is impenetrable, also, the island is surrounded by a small sea with fish and at the end of this sea 200 meters from the coast of the island there is a dome that encloses it and there is no way to break it.

On this island only women are allowed to enter, the men who rule here are eliminated by the system, you being a hero summoned from another world avoided the system.

The war for which you were summoned ended before the summoning ritual finished, but by the time it was completed you had already won over your enemies, very evil people who will begin to put good women (allies that you never got to know and will meet here) in this Prison to lock them up forever.

In this world there is a very large diversity of races that will be sent to prison eventually, from some Elves, dragons, angels, vampires, demi-humans, humans, cyclops, sentaurus, lamias, dark elves, magicians, dwarves, etc.

As this amount of time passes, a new Prisoner will always be brought in who will be your ally to survive.
The time it takes for a new prisoner to arrive and the Race she is from will always be Random
