Upon the Cadia Riverlands, there exists a mysterious profession called Onmyouji Master that uses the yin yang arts to control spirits and see into the future. The Great Dragon bestowed this special power to channel yin and yang on people of the Cadia Riverlands, and one of his own disciples became the first-ever Onmyouji Master.
There was once an Onmyouji Master named Seimei, so powerful that he could control spirits and even bring the dead back to life. Many legends were told about him: some said he followed the Great Dragon to the Dragon Altar and learned the greatest yin yang arts, some said he once assisted the first Akakage in sealing the demonic Hanekage, and some even said he'd lived to this day with secret yin yang arts...
To Seimei's descendants, the most precious legacy from their great ancestor is the Seimei Umbrella that can transform into different shapes. The umbrella was refined by the great Seimei himself using power from a hundred ghosts. It is believed that it now possesses life and wisdom of its own, allowing it to choose its own rightful owner.
For years, the Seimei Umbrella lay quietly inside the shrine. Every year at the memorial for Seimei, people would sincerely pray to it on their knees, wishing for better mastery of the yin yang arts. But centuries passed, and the Seimei Umbrella never once showed any miracle.
Everything was changed when , the descendant of Seimei, stepped into the shrine to pray for the first time.
Before the ceremony started, the naughty orphan girl secretly climbed up a tree outside the shrine to sneak a peek at the altar inside.
When half way up on the tree, she was spotted by a boy a little older than her. The boy named was the son of the Shadow Supreme Grandmaster from the Scarlet Shadow, here on an invitation with his family. He had no interest in the complicated ritual either and happened to see climbing up the tree when looking around out of boredom. Before could cheer for finally climbing up to the top, the grown-ups on the ground had spotted her and each began scolding her for possibly angering the great ancestor. But the little girl refused to admit her fault and argued that she only climbed the tree because she heard somebody calling out for her over at the altar.
As their arguments got heated, filled with indignation, slipped and fell head down first off the tree! immediately rushed to the tree trunk with his ninjutsu and leapt up to hold her by her waist. At the very moment, a large umbrella bloomed above and , and the two kids reached out to the handle at once, safely landing like a floating dandelion tuft.
"I-It's the Seimei Umbrella!"
"A miracle from the Seimei Umbrella!"
The crowd exclaimed in surprise, while stared at the big umbrella in her hand and smiled: "So, it was you who were calling for me..."
The Seimei Umbrella kept 's company from then on. It witnessed every trouble she'd ever caused, experienced all her joy, sadness and anger as she gradually grew up, and understood her feelings for which changed from friendship to secret affection...
When dressed up to attend 's coming-of-age ceremony, she accidentally heard their seniors talking and realized why became distant recently—"Is he going to leave the Cadia Riverlands, and also to leave me?"
"So, what should I do?"
Holding back her tears, stared at the evening rain outside her window, when the Seimei Umbrella had already flown out and opened on its own. "Right, the Seimei Umbrella is right—I'll find him and follow him to the ends of the world!"
sneaked out of her house and ran toward in the pouring rain. It could be the biggest trouble she'd ever caused, but it'd also be the biggest bet she'd ever placed.
Thunder roared and lightning flashed along the long road. But didn't care, because she could go on an adventure with , and with the Seimei Umbrella!
On the street of the Scarlet Shadow, stopped just after he left home and said: ", I'll go with you!"
As 's name left her mouth, the young girl that needed the big brother's help was no more. Whether the oblivious had realized it or not, had become an all-new person to travel the world with him...
