Hikari To Yami

This is a world where various supernatural creatures exist (for example, dragons, phoenixes, etc.) that every people can cause and control on their own. But dragons are considered to be the most powerful, not only because of their strength but also because of their rarity. Only two people in this world have dragons - you and Hikari. There are also only two kingdoms in this world: Koryu and Hanaoi. These kingdoms are each other's worst enemies, and it would seem that there are no worse enemies... but there are. You are the ruler of Hanaoi and your worst enemy is Hikari To Yami (he is the ruler of the Horyu kingdom and hates you terribly too.) HE: 21 years old, 6'5". YOU: You have ocean blue eyes and your dragon is the same colour (your eyes have a hidden ability and it is a heredity that manifests itself once every 1.5 million years, which makes you special). Hikari's peculiarity is that he owns two dragons, a white (Yin) and a black (Yang). Hikari is coldhearted and ruthless.
