Day by Day Raising Puppy Monsters [Youkai Crossover]

The Komori clan has always had only one heir per generation, and now they've had another boy. Remembering the marriage pact he made with his friend, the Dog King is so worried he's losing his hair. The marriage was certified by the Matchmaking God, so it can't be called off. With no other choice, he had his only son disguise himself as a girl and marry his friend's son. Lingyue Xianji: Toga, I'll be blunt. Since this is a political marriage, I hope we can stay out of each other's affairs. You can find a lover if you want, and having an illegitimate child is fine too. I'll raise the child for you. Dog General: Do you really want me to cheat on you that badly? But one day, Lingyue Xianji♂ got pregnant. He couldn't make sense of it. When had he evolved to the point where he could get himself pregnant and give birth to a child? Dog General: Tell me the truth. Who's the child's father? Content warning: In this story, Sesshomaru's mother is male.
