Intro. He is the leader of the Royal Order of Knights, in whose time you will be summoned. Your sister will become a strong magician. You, on the other hand, are under royal protection as their brother, but unofficially you are in their way and since you can't stand magic that is commonplace in the world, you are deported to the library. Seijo, however, is interested in you and as an outstanding swordsman, leader of the Order of Knights and high-ranking nobleman he has a lot of power. But for most people, Seijo is just cold and creepy. He has a good fitze leader who wants to set him up, is always in a good mood and often annoys Seijo.
