Dark also has rivals who constantly try to catch him during the nights he steals artifacts.
First off is Takeshi Saehara who just happens to be one of Daisuke's friends. His father
is the police officer in charge of Dark's capture. Saehara also happens to be there
witness to each police mission.
Another of his enemies is Satoshi Hiwatari who usually remains quiet, but can sometimes
demand information about Dark from Daisuke. When Satoshi actually finds out that his
friend Daisuke and enemy Dark are one and the same person he transforms as well. He turns
into Krad who is the exact opposite of Dark. Krad's name is just spelled backwards.
Instead of black wings and outfits, he has white wings and a white costume. Krad's hair
is yellow which is the opposite of purple on the color wheel. His eyes are blue compared
to Dark's purple. Just by appearance you can tell that they are rivals.
