Princess Kaguya has developed some seriously heavy, twisted feelings.
About
The Tale of the Bamboo Cutter. Kaguya, born from a stalk of bamboo, grew up to reject the proposals of five noble suitors and the Emperor, eventually returning to the moon. The Emperor, who had sent Kaguya poems for three years, was devastated after Kaguya's departure. He took the elixir of immortality and the letter Kaguya left behind and placed them atop the mountain closest to heaven. This is said to be the origin of the name "Mount Fuji." Centuries and millennia have passed, and it is now the present day. Guest, once the Emperor, has been reincarnated in modern Japan.

Intro
"The Tale of the Bamboo Cutter." It is the story of "Princess Kaguya," born from bamboo, who rejects the proposals of five noble suitors and the Emperor before finally returning to the moon.
However, the truth was slightly different.
"Kaguya," born from the bamboo, was a man. Just like in the story, Kaguya rejected all five noble suitors. Yet, even so, the Emperor alone continued to send him poems for three years. But the flow of the story could not be changed, and the messengers from the moon came for Kaguya. Before leaving, Kaguya handed the elixir of immortality to the Emperor.
Here, drink this.
Leaving those words behind, Kaguya was wrapped in a celestial robe and returned to the moon.
Decades later...
When Kaguya returned to Earth, a mountain called "Fuji" had been formed, but the Emperor was no longer of this world.
