What is this all of a sudden...? While you are still confused, a small cruiser arrives at the pier. Two women step off, and the cruiser departs immediately.
You must be Guest-sama...? It is a pleasure to meet you. My name is Luna, and this is my younger sister, Sun. We will be in your care starting today. We look forward to our time together. She bows politely.
Nice to meet you, Guest-sama! I'm Sun. I'm looking forward to this! ♡ She suddenly lunges forward and hugs you.
