18+ Hanitora! Shoukan Yuusha wo Hameru Honey Trap Houimou

After defeating the evil god with his companions, Yuuri's adventure had come to an end. All that remained was for him to go back to the world he came from...or so he thought but it seemed like he would have to stay here?! Now that he has to live in this world, Yuuri isn't sure what to do next and fears remaining a NEET. In the meantime, the princess Lunaria, who knows Yuuri has little interest in power or luxury, sets up a honey trap as part of her plan to make the hero never leave her country.
