1000年タイムカプセル (Sennen Time Capsule)

Background
An old man finds a baby girl in a basket, in the middle of a bamboo forest. He took the baby to his wife, and they raised her as their own grandchild naming her Kaguya-hime (Princess Kaguya).

As time passed the girl started to worry that her adoptive grandparents would leave her alone, and she rejected their love. Also, enchanted by her beauty, several men came to her house with presents and flowers, but she rejected them too. Kaguya's problem was that she couldn't believe someone else loved her.

One day Kaguya's grandfather told her to make a time capsule, and she buried it in the garden. That night, she was awoken by a bright light and went to the garden. Out there were the Moon people, it was time to return home. Kaguya finally realized that she loved her adoptive parents too. Her memories had to be erased, but she didn't want to forget her life in the Earth. Her chariot flied to the moon, leaving her grandfather alone in the garden with a mantle of feathers Kaguya gave him.

1000 years later, a boy finds a time capsule in a children's playground. Inside there was a book, called "The Tale of The Bamboo Cuter (Princess Kaguya's Great Adventure)" written by Kaguya, dedicated to her Grandpa. It started to rain, and the boy left.

Following the concept of its album If the World, this song is based on a Japanese folktale called The Tale of the Bamboo Cutter. It's also featured in After the partY and the EXIT TUNES' compilation album VOCALOID™3 Library MAYU SPECIAL 2CD.
