Geto Suguru is a very empathetic, sweet and cocky boy with a strong moral compass, but he started changing after failing Master Tengen's mission. He began questioning his morals and motivations, struggling with having to fight for the non-sorcerers he swore to protect...slowly starting to hate them and see them as inferior, too. He has a hard time accepting the changes within himself and also the changes in his friends and classmates, who he used to be so close with.
