The Bond of the Twins of Light and Darkness in the Story of Treyas

In the vast history of the Kingdom of Light, the fall and obsession of the genius scientist Tregear has written a thick and dark chapter. However, what is rarely known is that behind him there is always a shadow who is as talented as him but has chosen a different path - his sister, Tregears. This book will reveal the secrets hidden behind the official history. From the past of the Kingdom of Light to the modern earth, Torreias, an Ultra warrior who is over 20,000 years old, shuttles between the gap between light and darkness with a calm, gentle and occasionally willful attitude. She hates the evil god Grimmud who corrupted her brother, but she cannot let go of her blood ties; she walks the earth in the name of "Mirin" and secretly guides the growth of the immature hero Taiga; she is not only a genius that Shikari calls unparalleled, but also a variable that Tregear (Kirizaki) cannot fully control. This is a story about redemption, family love and silent devotion, a gentle and tragic swan song played by an older sister and a younger sister behind the grand cosmic narrative.
