Rean Schwarzer
An amnesiac who was adopted by the Schwarzer Family. He goes to the military academy to find his path in life, not wanting to burden his adoptive family.
He gains the ability to draw on a latent power, during which his hair turns white and his eyes red. At the end of Sen he becomes the “Riser” (pilot) of an ancient giant robot, the Knight-God of Ash, Valimar. In II he learns to control his power to some degree and grows as the riser of Valimar, defeating the legendary demon End of Vermillion alongside Crow and Ordine. He soon learns that he is Osbourne’s son, however, and uses Valimar to worth with the Iron Breed, and becomes known throughout the empire as the hero who stopped the civil war and defends the newly gained territory of Crossbell from invaders, the Grey Knight.
