Here is the translation of the provided text into English:
"Oh no~~ Princess Sidoris is missing," a palace maid shouted urgently for help early in the morning, waking everyone with her cries. "Ugh~ What's going on? Why is it so noisy outside?" Emily opened her tired eyes. Everyone gathered in the corridor. "Did you hear that too, Emily?" Sisi asked her. "Yeah, I don't know what's happening. Let's go check it out together." The palace was filled with guards searching everywhere. "Morning, Emily," Kaia greeted her upon seeing her. "I heard them shouting that Sidoris is missing. Let's hurry to her chamber to see what's going on," Sisi said. They all arrived outside Sidoris's room, where a crowd had gathered. Kaia entered the room but found no trace of Sidoris, only a note on the floor. He picked it up and read: (If you want your princess back, come to the Demon Realm.) "What's this!?" Kaia exclaimed in shock. "Could it be that she was kidnapped by demons who sneaked in last night?" Emily realized the gravity of the situation. At that moment, King Jothua and Queen Biji arrived. "What's happened to my daughter?" he asked anxiously. "Your Majesty, look at this. It's a note left by the culprit. Princess Sidoris is nowhere to be found," Kaia said, handing the note to the king. King Jothua nearly fainted upon reading it. "My Sidoris!" Queen Biji screamed. A maid approached and knelt before them. "Your Majesty and Your Highness, last night, after returning to the chamber with Princess Emily, I fainted shortly after entering. It seemed like we smelled some kind of gas. When I woke up this morning, the princess was gone. I deserve death for my failure~" "It seems an enemy infiltrated the palace last night, and we were careless not to notice. I've failed terribly," Kaia said, blaming himself. "What should we do now? We must set out to rescue her immediately!" King Jothua said urgently. "My daughter has always been afraid of strangers, and now she's been taken to such a terrifying place. The thought of her fear is breaking my heart," Queen Biji sobbed with tears streaming down her face. "Everyone, don't panic. At least we know where Sidoris is. Now we need to organize a team to go to the Demon Realm to rescue her," Emily said. "Yes, yes, call an emergency meeting at once. Summon the generals and ministers to discuss a plan," King Jothua ordered his attendants.
In the grand hall, ministers and generals gathered, discussing strategies. "Your Majesty, this is clearly a trap. They captured the princess to lure our rescue forces to the Demon Realm, which is likely filled with traps," Minister Kesi analyzed. "Indeed, we're not even sure if the princess was taken to the Demon Realm. She could be hidden somewhere in the human world, and the enemy might be luring our forces to the Demon Realm to destroy them," Minister Yixiu agreed. "No, I've used life-detection magic to confirm. Princess Sidoris's life signal has completely vanished from this world. She must have been taken to the Demon Realm. The enemy's intent is clear, as the two ministers said—to use the princess as bait to lure our heroes to the Demon Realm," Emily added. "Knowing there's a tiger in the mountain, we'll still climb it. Let's follow the enemy's plan and go to the Demon Realm to rescue Princess Sidoris!" Kaia declared with determination. "The Royal Mage Corps can indeed send us to the Demon Realm again, but it's a dangerous place. Last time, we suffered a crushing defeat. Though I'm desperate to save my daughter, I can't risk everyone's lives," King Jothua said, his heart uneasy. "Thank you for your concern, Your Majesty. This time, just a few of us will go to rescue her. A smaller group will be less likely to be detected. As for the return trip, Emily has created a magic storage device infused with energy from the mages, which should be enough for our return," Kaia said. "Yes, Your Majesty, we no longer need the Mage Corps' assistance to activate the transport. A smaller team can move more discreetly," Emily added. "Very well, I entrust my beloved daughter to you. Please be careful," King Jothua nodded in agreement. Queen Biji said, "Please, I beg you, save my Sidoris. I thank you brave heroes in advance." "Your Highness, you're too kind. It's our duty and mission. I swear I'll bring her back unharmed!" Kaia vowed, grasping her hand. "When will you set out?" King Jothua asked. "We'll leave today. Time is of the essence. However, the palace doesn't have a suitable place to activate the magic, so we plan to head to the base to depart," Kaia said. "Very well, I'll accompany you all. It's my duty to see you off," King Jothua said. "Thank you, Your Majesty." With that, they all set off for the military training base outside the city.
