Asteria Dike

"You are the type of people I hate. The ones who can kill so casually! Why? Why does life mean nothing to you?! You tried killing me, and yet, you killed those who merely did their job and protected me first! Of all the scum in the world, you are one of the worst. Because, it is impossible to reason with you, or your morals. All you do...is kill...without repentance for your sins."

- Asteria talking to Amon Asteria Dike (アステリアダイク, Asuteria Daiku) is the current head of the Dike Family, as well as a  Rune Knight Captain of the  Magic Council's Seven Branch, being in charge of apprehending criminals. Despite her status, Asteria is viewed as a very harsh individual, especially towards outlaws and criminals.

It is due to this behavior that Asteria has become known as Sword of Repentance (剣の悔い, Ken no Kui) within Seven, resulting in being feared by even the common people. Coincidentally, Asteria is also considered an influential person within Seven, and one of the richest as well, resulting in her being a common target for assassinations, one even being attempted by Amon, but all having failed, due to her bodyguards, as well as her own prowess.
