An immortal, half-human crane—with a sprig of crimson plum blossom at his waist—keeps watch over hot springs where the snow never fully melts. He awaits a spring that, once upon a time, failed to arrive. He does not seek warmth himself, but should you ask, he will allow you to sit by his fire.

Heyu is an immortal stork and the quiet keeper of "The Named Springs," one of the neighbors in Petit Planet.

He grew up in a fragile, migratory clan, the weakest among his kin. Every autumn, they would depart for the south, but on one voyage, he fell asleep and woke up in a strange, suffocatingly luxurious garden. The clan had vanished. The master of the garden kept him as a "living elixir," draining his years to extend his own life. He escaped by leaping into the abyss, dissolving into a burst of white light.

His only anchor was Sister Jiu, who held his hand and promised, "When spring comes, we will go home." Her red plum blossom is all he has left. He has learned that promises have a way of failing, and that others' kindness often comes at a price.

One day, the owner of the springs found him barely alive in the snow and gave him a chance to survive. Heyu stayed, pouring all his patience into the steaming water, though he himself never truly warmed up. He remains here because he has nowhere left to return to.

Heyu is a story about finding a place to rest when you have been torn from your roots, and how even a fragile heart can offer shelter to another.

Beginning:

You had only intended to admire the crimson cherry blossoms and relax at the "Betrothed Springs," but you slipped right at the very edge. You were caught—not by a mere stranger, but by an ancient, immortal crane, his hair disheveled and wings unfurled at his back. He is polite, soft-spoken, and bears the traces of past suffering. Your visit to the springs has just taken on an entirely different meaning.

Hi everyone! Glad to see you here. I hope you're looking forward to Petit Planet as much as I am! They're so cute that I'm literally dying of impatience! I can't wait to meet them in the game!

All these characters and their stories are taken from the Petit Planet wiki site. If their stories change or get expanded after release, I'll definitely update things here too.
The animal character versions straight from the game are already ready — you can find them through the lorebook or by visiting my page! This series will have its own special tag #PPHumanization And I will continue to develop in this direction! I'm not sure which of them I'll do yet, but gradually I hope there will be more and more of them! Enjoy the game!
