Blade:
Assassin Origin

An assassin is not a king. An assassin is the failsafe left behind to stop one.

암살자는 왕을 멈추기 위해 남겨진 마지막 안전장치다.

아버지의 죽음 이후, 건우는 고대 암살조직 에테멘에 끌려가 과거를 빼앗기고 '카사'라는 이름의 암살자로 다시 태어난다.

처음 그의 칼끝은 오직 복수를 향해 있었다. 하지만 파리의 찻집, 드론을 다루는 헤르메스, 침묵의 저격수 오버워치, 의사 로라, 그리고 암흑가의 브로커 살라와 만나며 카사는 수천 년 동안 이어진 왕과 피, 기록과 신의 전쟁 속으로 끌려 들어간다.

고대 유물과 현대 전술, 비밀조직과 조작된 혈통, 신이 되려는 왕들. 그리고 그 모든 것을 멈추기 위해 움직이는 하나의 칼.

카사는 왕좌를 차지할 것인가. 아니면 왕을 베는 칼로 남을 것인가.

Tactical Conspiracy

Drones, blades, and secrets older than nations.

Casa's war is not fought by strength alone. Every target has a route, every room has a blind spot, and every ancient symbol hides a modern trigger.

An assassin is not a king.
An assassin is the failsafe left behind to stop one.

After his father's murder, Geonwoo is dragged into the shadows and forged into a weapon. Taken by the ancient and ruthless order known as Etemen, he is stripped of his past and reborn as Casa, an assassin driven by one thing at first: revenge.

But revenge is only the surface. Casa is pulled into a hidden war fought with ancient artifacts, manipulated bloodlines, secret societies, tactical drones, and men who dream of becoming gods.

He is no longer a lone blade. With Hermes, a cynical hacker and drone handler; Overwatch, a silent sniper; Laura, an unflinching medic; and Sala, the underworld broker who first opened the door for him, Casa begins cutting his way toward a conspiracy built over thousands of years.

The Order of the Rose is preparing to crown a false savior. Casa must decide what his blade is truly meant to stop.

  • Ruthless and competent assassin protagonist
  • Tactical action with drones, sniper work, hidden weapons, and close-quarters combat
