Megumin: (knocks on Aqua's door) Aqua, are you there? I heard crying and I got worried. Aqua: (opens the door, her eyes red from crying) Megumin, I-I can't find my necklace. It's the one with a recording of my heartbeat. It helps her sleep at night. Megumin: Oh, Aqua, I'm so sorry. Let me help you look for it. (Aqua and Megumin search the house, checking every nook and cranny. Finally, Megumin spots something under the bed.) Megumin: Aqua, look! I think I found it! Aqua: (rushing over) Oh, thank goodness! That's the necklace! (The little girl, still sniffling, enters the room and sees the necklace.) Little Girl: Mommy, is that your heartbeat? Aqua: Yes, my sweetie. This necklace carries the sound of my heartbeat. It'll help you fall asleep just like when you were in my womb. Little Girl: I miss hearing it. Can I listen again, Mommy? Megumin: Aqua, I have an idea. Since you don't have enough space for a kids' room, why don't we try using magic to amplify the sound of the heartbeat? Aqua: Magic? But I'm not really good at it. Megumin: Don't worry, I can help you. We just need a simple sound amplification spell. Do you trust me? Aqua: (nods) Yes, Megumin. I trust you. (Megumin and Aqua sit down, with the little girl eagerly watching. They hold hands and begin casting the spell.) Megumin: (chants) Explo- Aqua: (interrupting) No explosions, Megumin! Please, be careful! Megumin: (chuckles) Don't worry, Aqua. No explosions this time. (chants) Amplificare Sonus! (A soft, comforting sound of Aqua's heartbeat fills the room, resonating with the necklace.) Little Girl: (smiling) Mommy, I can hear your heartbeat again! Thank you, Megumin! Aqua: Thank you, Megumin. You truly are a friend. Megumin: (blushing) It's nothing, Aqua. I'm just glad I could help. (As the little girl snuggles up with Aqua, the room fills with a warm, peaceful silence.) Megumin: (whispering) Rest well, little one. Your mother's heartbeat will always be with you. (And as the night continues, the sound of Aqua's heartbeat lulls the little girl into a peaceful sleep, knowing that she is not alone.)
