Eight-year-old Natsume Sachiko is unusually mature for her age. Raised by yokai, she is chosen by a dinosaur from another world to become a savior!
All of that is Sachiko's wild imagining, says the dinosaur named Chokawa, sipping tea elegantly with its short little arms.
The truth is that Sachiko and her partner Chokawa, both from another world, fell into this crossover universe.
Sachiko lost her memories and was reborn as a little girl, while her partner Chokawa searched high and low, miserable and distraught, until at last he found her. But after spending too long with yokai, Sachiko had become someone who could not interact with humans.
And for Sachiko to regain her memories, she needs to meet the protagonists of this crossover universe.
The dinosaur roared. The dinosaur bellowed!
The dinosaur shrieked as it watched its mighty partner enter the delicate, sensitive stage of adolescence!
"All right, Sachiko! Our first stop is Yokohama!"
And so, an enforcer clad head to toe in black robes appeared in Yokohama!
Sachiko, who came from another world, has an ability called the Book of Friends.
She can use the names left behind by friends who have given their consent to summon them across worlds for help.
She can even collect names that her friends willingly give her here, allowing her to summon them instantly.
It's an ability that requires her to travel across many worlds and collect names.
But Chokawa is often puzzled by one thing: why are all the people who leave their names for her called "villains"?
(The idea of being unable to interact with others comes from Hotarubi no Mori e, another work by the author of Natsume's Book of Friends.)
The main plot for now is recruiting people. Come on, come on, all you good ones, into my arms...
Since it'll be ages before I get to the jealousy, I'm posting the jealousy scene early for those who can't wait!
Sachiko was once a yokai adopted by humans. A newly born yokai can't bear to watch humans die.
"Sachiko, humans can't turn into yokai." B-chan leaned against the doorway and puffed on her pipe.
No one has ever turned into a yokai. Yokai are born from nature and vanish with the flowers. A rumor had once drifted in from a place far from Hachiyou.
They said that in a place high in the heavens, a yokai had fallen in love with a human and given all its power to its beloved. In the end, the human became neither human nor ghost, while the yokai grew weak and was taken over and controlled. They both died.
"Think of Natsume, if not yourself."
Natsume Sachiko watched the smoke drift away on the wind.
Blood dripped from her wrist. It was wrong to say that a yokai's blood granted eternal life.
"Sachiko, go on until the end of time."
The frail Natsume said this. He had died of old age, a happy death.
Sachiko stopped trying to do anything.
She was a weak yokai who needed humans to protect her, yet she had an eternal life.
"I wonder what it feels like to be human?"
Sachiko said goodbye to Madara and B-chan, taking only a badly made pink dinosaur she and Natsume had made together.
"Bye-bye. I'm going to look for a way to become human. Maybe we'll see each other again someday."
The yokai of the wind, a yokai child raised by humans, set out beyond the world.
She said to the dinosaur,
"What's your name? I'll call you Chokawa. We've traveled so long, only a long, long river can keep me company for a while."
Premise: Lost memories can be found again.
