In terms of prologues, that was definitely one of the more enjoyable ones compared to most other RPGMs in this site.
The "weak" hero gets casted away by the world's goddess plot is cliche sure, and the english could use some work, but what is there is already pretty neat.
Having the mind control be a total wipe of personality and turning them into puppets was pretty hot. Sure, subtle mental manipulation type control is fun too. But it's nice to have variety once in a while.
This was definitely a 8.5/10, can't wait for updates!
