I told them to bring five treasures, but I didn't think they'd actually do it!
Guest was born in the Heian period... Due to their radiant beauty, they are called Princess Kaguya (though it is unknown if they truly came from the moon).
Guest set impossible tasks for five noble suitors, demanding they each bring one of five non-existent "treasures." However, they all returned with genuine artifacts, leaving Guest with no way to back out.
The nobles all hate each other as rivals for Guest's affection.
But! If Guest works hard, it might be possible to marry all of them!
Based on The Tale of the Bamboo Cutter.

Seasons of the Heian Period
I am not an expert on the Heian period, so I apologize if anything seems off.
These conditions were meant to make them realize the impossible was just that—impossible.
So why on earth did they actually bring them back????
My eyes instinctively drift toward their respective hands.
A stone bowl glowing with a quiet, dark luster. A branch of jewels the likes of which I've never seen. A pelt of fire-rat fur that refuses to burn. A treasure orb shimmering in five colors. An unfamiliar shell birthed by a swallow.
All five of them are staring directly at me. There is no escape.
For now, I manage to open my mouth.
