I'll show you the gates of Hell...
Gaikoz is a ghost knight that is fought as a boss in Gaikoz's Castle.
Gaikoz was once a warrior who lost his lady love in the war and then lost his own life when he fell into a trap. Later on, Kaze'aze resurrected him and all of his resentment from the tragedy and hatred for humans built a body, turning into the specter that he was.
When Gaikoz himself was confronted, he mocked the Grand Chase by saying that they were resisting what could be a "bright future" and creating such a thing calls for great sacrifices as Lady Kaze'aze taught him so. The ghostly samurai was eventually slain by the Grand Chase.
Sanctum of Destruction
Tower of Disappearance
The vengeful Gaikoz was once again encountered as the Grand Chase ascended the tower.

Epilogue 7.3: Tower Gatekeeper
After Stellar called for the gatekeeper, Rin noticed that the enemy troops were that of Gaikoz's. Then they learned from Io that all of the monsters encountered since entering the Tower of Disappearance were not illusions, struggling to defeat the vindictive spirit who has gathered so much energy in just a short amount of time during the battle.
Gaikoz's attacks are that like a ninja and samurai. He occasionally teleports to a party member while accompanied by a ching sound to attack them from behind before sweeping his sword to hurl 3 rocks. He can also hurl the rocks without teleporting. When players are far away, Gaikoz will often generate two ranged energy waves that have an infinite range in front of him. Sometimes he will do a dash attack. Finally, Gaikoz has a DANGER attack where he rapidly attacks the area in front of him, covering it in calligraphic writings that if not dodged will usually kill players who pose weak Defense or Vitality. He is invincible throughout this attack.
In Gaikoz's Castle, Gaikoz has two Ghost Bladers guarding him and he is capable of summoning more if any die. When summoned from the Boss Gate, Gaikoz retains all of his attacks in Gaikoz's Castle. However, he is more dangerous in the sense that he is more likely to perform his teleport technique when attacked.
4 of them can spawn in the Sanctum of Destruction, becoming more powerful. The Vengeful Gaikoz can throw weaker but directional energy waves in an arc radius in front of him and has two DANGER attacks where he either makes a unique but powerful frontal slash or that he dashes and slices at strong damage and speeds, cutting all in his linear range.
Vengeful Gaikoz reappears in the Tower of Disappearance in a more menacing form.
