At the plaza some time later, the group sat close together at separate tables, showing the items they bought from the museum's gift shop.

"Check this out!" Subaru Ogawa, a green haired boy wearing a black trench coat and pants with a green shirt underneath the coat, said as he showed off his emerald necklace.

"Bet you can't find this anywhere else!"

"Hah! That's nothing compared to my Ruby ring!" Amai showed off a ring with an authentic ruby gemstone in it he was wearing. "I'm sure I'm gonna win girls over with this!"

Angel Seraphina, a teenage girl with long pink hair in a ponytail, rolled her eyes. At a nearby table, Kaguya stared at the shard of the moonstone necklace she received, entranced as she was before. Looking at it, she noticed that the colors were the same as the void space she was in while in her dream. Could it be that she was in that very moonstone that night?

"Miss Kaguya? Are you alright?" Rosalie asked, snapping her out of it.

"You've been staring at that thing ever since you bought it!" Mimi added.

"Forgive me. It's just…it's so beautiful." She stared at the moonstone again. "And…I feel as if it's calling to me."

"Calling to you?" Mimi repeated. "Kaguya, it's a crystal. A rock. It doesn't have thoughts or a voice."

"You don't understand! Last night, I had a dream. I was inside the moonstone and I heard a voice. They said something about a grave danger."

"A grave danger?" Rosalie placed a hand to her chin in thought. "That is quite strange. But it's probably nothing to worry about. After all, sometimes dreams don't have meanings."

"Don't have meaning?!" Kaguya repeated, jumping out of her seat. "This dream I had certainly has a meaning! If anything, this dream was more of a message. And I'm gonna find out more!"

Mimi and Rosalie shared concerned glances.

Later, back on the moon, Kaguya was dressed in her blue nightgown, ready to turn in. She put on her moonstone necklace and got into bed, slowly closing her eyes.

Kaguya opened her eyes and saw that she was back in the moonstone.

"Kaguya…" she heard the voice again.

"Who are you?" Kaguya wondered, looking around. "Where are you?"

"That does not matter, Kaguya," the voice said. "A grave danger is approaching…"

"What grave danger are you talking about?" the moon princess asked.

"It is a danger that cannot be explained. But only you can prevent it."

"How?"

"Find the Cosmic Moonstone."

"The Cosmic Moonstone? What is that?"

The moonstone shone bright again, blinding her once more.

Kaguya awoke from the dream and looked at the necklace.

"I know what I have to do now."
