A crossover between the game Onmyoji and Natsume's Book of Friends
When Natsume Mei was born, her soul split in two.
One part remained in □□, and she grew up looking like an ordinary human.
The other part traveled through time to the Heian era, a time when demons and spirits roamed freely, and was adopted by Abe no Seimei, the greatest onmyoji of the age.
Then an accident brought the soul back together. The adopted son of the greatest onmyoji in Heian-kyo vanished without a trace, surviving only in legend.
The adopted son of the Fujiwara family had been missing for a long time. Some said that the last time they saw him, he was heading into the deep forest in the mountains.
Large numbers of patrol officers and safety personnel were sent to search for him. Nearly half a month of investigation yielded no results...
On the final day of the search, just as everyone was about to give up, they found him...
He lay beneath a towering tree, his face rosy, hands crossed over his stomach, like a sleeping beauty in a deep slumber.
