The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them.

Growing up with eccentric materialist parents who left him in the care of his grandfather for a job overseas, Zhang Heng had learned to adapt and be unfettered by the oddities and challenges in life. But he would soon learn the baffling truth about the world he thought he knew when one day at midnight time froze and he found himself in a world so quiet and still it was deafening. That night, he discovered that he had 24 hours more than everybody else and thus, marked the beginning of his adventures. The mysteries surrounding his newfound ability only deepened when a strange old man claimed to have given Zhang Heng that ‘gift of time’ and recruited the young man to participate in a cryptic ‘life-changing’ game on his behalf. Little did Zhang Heng know that accepting those terms meant embroiling himself in many versions of reality and exposing himself to the hidden secrets of the world—a decision he could never undo.

Before I woke up, I had a dream about the end of the world. At first, it felt like a vivid nightmare that left me shaken. But as I slowly woke up, I realized that the dream was the pre-ending scene of my own novel.I am Zio Varrez, an unnamed character in my own book, and to my disappointment, an extra. As I lived in my novel's world, I couldn't help but feel that my existence was meaningless. But what made it worse was the fact that the ending of my book was the end of the world - a bad ending.I knew I had to do something to become strong enough to change the world's fate, even if it meant altering the story I once knew completely. Little did I know, there was more to this world than I realized, and the journey I was about to embark on would uncover secrets that I never even imagined.“I thought I knew everything about the world, but as I lived and experienced it, I realized there was so much more to it than I ever imagined.”
