Night Before War IV (R-18)

 Alros looked at Mina with raised brows.

 "Why the sudden question?" he asked.

 "You are going to war with an entire nation. And while I believe in you, I still could not help but be worried. At least, if something happened, I will carry on your child," she replied as she looked away when she said her piece. 

 Alros smiled as he patted the head of the Witch. 

 "One day, we will. But not now. The most idealistic time would be when I become strong enough to pose a threat to the world. That's when I want to sire a child," he replied.

 In other words, he wanted to become a Demon Emporer, the strongest being of the Demon Race, one just below the Demon God.

 Mina have a wry smile on her face hearing that.

 "Won't that mean I have to wait for a long time?" she asked.

 "Maybe, but I will not remain idle you know? I will do my best to become the strongest," he said as he rubbed her back, earning cute nods from the twin-tailed Witch.
