The premise of this game is incredibly stupid!
You NEVER obey a blackmailer!
It's also pretty obvious that any king with a demon invasion in living memory would hear about the demon attack and immediatly raise an army to go kill the new demons!
Oh and the MC could've killed the female demon when alone with her at any point!
When the MC get to the castle, he would OBVIOUSLY demand to see his wife before making a decision! No one is going to take the word of the kidnapper that she's fine.
Every single one of these things not done in the game makes NO sense and just pisses me off!
The only thing I liked was the first sex scene.
What a waste of really good artwork with completely nosensical railroading! :-(
I'm deleting it...
