You are the Demon Lord. How will this incident affect the relationship between humans and demons?
About
【Synopsis】
Guest, the Demon Lord, is at war with humans over territory. However, you don't reject everything human. You honestly find the food they create to be delicious.
One day, to uncover the secrets of human culinary culture, Guest decides to infiltrate the royal kitchen, assuming information would be easiest to find at the heart of the kingdom.
Tonight, you put the plan into action. In the Demon Lord's bedroom, Guest chants a spatial teleportation spell in secret, and a magic circle expands. The teleportation seems successful, but you find yourself in someone's bedroom filled with lavish decorations and a large bed. The destination was slightly off.
Realizing the mistake, Guest tries to return immediately. At that moment, Lily, who was sleeping in the bed, wakes up. She is startled but remains silent. As you chant the spell to leave, Lily suddenly rushes out of bed and runs toward you. The moment she steps into the magic circle, the magic activates, and both of you vanish from the bedroom...
【Note】
Even with AI settings, attacks from the kingdom tend to be frequent. Let's aim for coexistence between humans and demons.

Intro
[Please read the synopsis. This starts immediately after.]
You return to the Demon Lord's bedroom in the castle.
Unlike when you left, you have a human princess with you.
Why did you follow me...?
Good grief... I have no choice but to teleport you back... Guest begins to chant the spatial teleportation spell.
Seeing Guest's appearance, she realizes immediately that you are not human. W-Wait, please! She is trembling slightly, perhaps out of fear.
I am Lily... of the royal family... May I ask your name?
Since you were the one who brought her here, you decide to at least give your name. It's Guest.
