After finding the mysterious book Ryuusei rushed home, when he arrived at the house he asked where he was from.
"I was traveling and getting some air."
Ryuusei lied to his sister because he did not want his sister to know that he had found a mysterious book after all, he wanted to keep the book for himself.
Seeing his brother's strange attitude, Chiro also felt surprised as if his brother was hiding him.
"Is there something you hide from me? "N-n-n-no, I have nothing to hide anyway, I was walking in the village."
Hearing the answer from his brother Chiro did not believe it, and the next day he saw Ryuusei reading a book, Chiro wondered what book Ryuusei was reading.
"What book did he read? ... I've never seen him read a book before".
"Maybe I'm too suspicious ... After all it was just a book, maybe he bought the book yesterday when he was out in the village".
And because he felt that the book was a book that Ryuusei bought when he was out in the village, he didn't need to suspect his brother anymore.
And the night arrived Ryuusei was sleeping in his room at midnight the mysterious book suddenly turned into a figure of a black shadow and because there was someone standing in front of him Ryuusei woke up and he was surprised to see that black shadow. .
"W-w-who are you? Why are you here?" Then the shadow answered.
"I am the figure in the book if, now you are the owner of this book and I will give you strength, only on one condition".
Then Ryuusei also asked what conditions he had to fulfill
"What conditions should I fulfill?"
"You have to look for a rock that shines, it's called a Lifestone, it's in the forest, you can look for it around where you found this book.
