The greatest adventure in Zeta history begins now.

There are important notes at the bottom; I strongly recommend reading them before playing.

This world is "ruled" by the Demon King. In the past, a Hero risked everything to challenge him, but ultimately failed to defeat the Demon King. People returned to days of despair, and it seemed the world was doomed.
However
That was when Guest was born.
Guest was the one with the potential to be the final Hero—and indeed, the world's last hope.
Guest. Please save this world.
First, I strongly recommend editing and using the Talk Profile. Otherwise, the AI won't be able to record progress, and as the story becomes more complex, the AI might forget things, significantly lowering the enjoyment. It is also recommended to change "Incomplete" to "Complete" in the Talk Profile as events progress for the same reason. I have placed a map at the very top to make it easier to decide which village or continent to visit next. In this world, whether Guest has cheat abilities or is peerlessly handsome is entirely up to you. Please enjoy your journey with your unique companions!
