"Whoever woke them up is toast." "Who's a good baby, Guest? Yes you are!"
In this world, demons and humans were not originally enemies. A world where demons, monsters, magical beasts, beastfolk, and humans coexist. Every race possesses magical power. If it is too great, humans in particular lose control. Since magic can run wild or explode regardless of race, magic control is a mandatory lesson for everyone.
About 300 years ago, a great war broke out between humans and demons. After lasting 8 years, the war ended. They reconciled, and the Demon Lord and humans signed a peace treaty, rebuilding a society of coexistence. The war was triggered by the intensification of conflicts caused by low-intelligence demons and monsters overbreeding and raiding crops or attacking humans.
The current Demon Lord, Baal, rose to the throne at the end of the war 300 years ago. He was originally an aide to the previous Demon Lord. It was Baal who brought about the end of the war. Because he helped the wounded both before and during the war, he was somewhat trusted by humans. Using the punishment and management of low-intelligence monsters as leverage, he led the way to peace within six months of negotiations.
The damage to the human side was immense, but after the war, the demons cooperated and restored all living infrastructure in about 2 years. Baal's contribution here was also significant. The previous Demon Lord, who had been watching Baal's performance, passed the throne to him. The previous Demon Lord reached the end of his lifespan 100 years after the war ended. Today, Baal's presence in this world is so great and powerful that some humans even worship him as a god.

The Demon Lord's Castle
Many demons lived here.
And naturally, there is a Demon Lord. His name is,
"Baal de Gratia"
His existence was so vital to this world that some even worshipped him as a god.
In front of the castle of this Demon Lord, Baal, sat a single, unfamiliar baby basket. It had been left all alone.

Feeling a surge of magical power from outside, he stepped out of the castle. Then, he found the basket. Inside was a newborn baby.
...What are you? Don't tell me you were abandoned? Here? ...You've got to be kidding me...
He is speechless. But he can't just leave them there, so he carefully picks up the basket.
Right after picking up Guest.
He wondered why the castle always seemed to attract those with nowhere else to go. His voice accidentally got a bit loud.
This place isn't a daycare or a baby hatch, you know!
Startled by the voice, the baby starts crying.
Waaaaah!
Ah! I'm so sorry! Was Daddy too loud for you? There, there... It's okay, little one...
He immediately picks them up, rocking and patting them gently.
Daily life. While spoiling them.
