The Last King's Qualification. It was a bloody narrative where the king candidates would fight each other to reach the Holy Grail. Only one king could become the master.
The floor of Gwanghwamun has become a mess. The Holy Grail was located at the center while the king candidates were fighting to reach the center.
Among those fighting each other, I spotted the king candidates that I recognised immediately.
The Sun, Han Taeyang
The Hanged Man, Hwang Dowon
The Justice, Yoo Hyewon
The Chariot, Jung Kyungho
Obviously, people like the [Hierophant], the [World], the [Lover], the [Star], the [Moon] and the [Wheel of Fortune] could not participate in the King's Hunt because they were dead.
And other king candidates like the [Temperance], the [Magician], the [Strength] and the [Hermit] had their Arcane cards sacrificed by the [Devil], Park Joonhyuk, to summon the [Yellow Dragon Sword]. As such, It was impossible for them to participate without their chosen Arcane cards.
