Takuro's life changes drastically when his home village is attacked by mysterious enemies. During the attack all of Takuro's loved ones are kidnapped leaving the young boy to fend for himself. With no other choice, Takuro embarks on an adventure to rescue his friends and family.

Soon Takuro learns the true nature behind the attack on his village. Ancient items known as the Shinseiseika (神聖成果, Sacred Artifacts) have existed in the world for thousands of years. According to many legends the Shinseiseika can grant strong powers and abilities to those that wield them. Many years ago a powerful warrior hid the Shinseiseika all around the world in hope that their power wouldn't be used for evil. An evil organization known as Chinmoku (沈黙, Silence) has been going around the world searching for the items in order to use them for their own nefarious schemes.
