They are half angel and half demon twin brothers named Branze and Bransel suddenly appeared in Telus one day, and because they were celestials (whom had already gone extinct in Telus) they were quickly taken to a lab and experimented on. The mad scientists would test their powers and even starve them for days. The twins soon would forget the vague memories they held of the celestial realm.

Eventually monsters invaded Telus and destroyed the lab, giving a chance for the twins to escape and break their restraints. They revengefully slayed the scientists who had tortured them. They later come across a temple and meet Platin who offers them food and shelter and they grow close and attached to Platin. They are known as troublemakers but Platin always shields them from getting in trouble.however the temple would be destroyed by Pallanus’ decision and explosion.

They agree to join the darks in hopes of rebuilding the temple but are then angered when they find out Pallanus is the one responsible for the explosion. Now they enjoy making chaos for the group. They get along well with Yeonhee and are always annoying her to play with them, she doesn’t seem to mind too much. The twins dislike Mercure and find him creepy but acknowledge that he wasn’t one of the scientists that experimented on them.

In seven knights 1 it was revealed that their mother, named Blanc, was a noble demon lady that had fallen in love with a celestial and given birth to the twins, however she had asked the mage Arianrhod to transport the twins to another time, to save them from falling victims during the war of celestial and demon kin in the heavens. Blanc sadly fell into the abyss but manages to save her twins, it is believed she does survive.
