**Chapter 1: The Birthday Gift**
Kaito's 16th birthday arrives with a mixture of excitement and trepidation. His family's financial struggles weigh heavily on his mind, casting a shadow over what should be a day of celebration. But when his grandmother, Hana, presents him with a weathered tome that once belonged to his great-grandfather, everything changes.
Bound in cracked leather and smelling of dust and age, the book pulses with a strange energy that Kaito can't quite explain. As he flips through its pages, he feels a stirring in his soul, a sense of connection to something ancient and powerful. Little does he know, this book holds the key to unlocking the mysteries of his family's past and his own destiny.
