The main protagonist of the series Chrome Shelled Regios. In the novel, he is described as having tea coloured hairs and blue eyes. He was one of the twelve wielders of the Heaven Blades and also held the title of Wolfstein at the age of ten. After being exiled by Queen Alsheyra for participating in underground matches for money (though it was for the children at the orphanage)[1] he came to Zuellni as a Liberal Arts student with a Scholarship Rank D and no interest in joining the Military Arts. However, he was forced to join the Military Arts after Karian Loss, head of the student council, saw his combat potential, where his scholarship rank is A and so all his scolar fees are payed. Layfon has extremely high combat capabilities, as can be inferred from his past as a Heaven Blade. Due to his birthplace, Grendan, being heavily involved in fighting Filth Monsters, he and fighters there developed with a 'win or die' philosophy.

Sakata Gintoki is a samurai living in an era when samurai are no longer needed. He is recognized by his natural curly hair and sweet tooth. He often blames his "perm" hair of sorts to be a source of some of his misfortune. Gintoki lives with Kagura and Shinpachi, taking on odd jobs to make the world a better place and to pay their rent. In the Joi war, he was known as the "White Demon" due to his silver hair and white coat he wore in battle, which, combined with his impressive capabilities as a swordsman, made him famous among his comrades and struck fear into Amanto.
