Insufficient Brave Team

Unsound, very unsound! The princess Freya, who carries the fate of the world, has been so weak and unable to move since she was born by the powerful magic given by the goddess. She has extremely high magic power but cannot perform magic because it cannot bear it. Her brother Leonard is a legendary and destined hero, tasked with defeating the demons. At the age of 16, he resolutely chose to bear part of his sister's cause and effect through a ritual. Although his sister's condition was alleviated, the price was the complete loss of eyesight. How can a blind hero with a heroic mission face the enemy? "Brother, let me be your eyes." Not perfect, very unhealthy!
