Cha/History

History
Following the war history of FUG against the Zahard Empire, at some point, like Dowon, Cha also seems to be one of the many outstanding Rankers from many countries who opposed Zahard to become king of the tower. He probably received special training under the masters at FUG as well. After all of these outstanding rankers completed their training, they were assigned in their respective special teams. Cha was assigned as the leader of Hidden Grove team, along with Dowon, Khun Hynd Luch, Taro York, Toro and three other unnamed members. During the war, the Hidden Grove team quickly gained notoriety as one of the best teams that emerged during the war after they successfully killed direct descendants of the 10 Great Families.

Three Months before Dowon was sealed, the Hidden Grove team members (Dowon, Khun Luch and Taro York) were being chased by the Ancient Odd-Eyed Giant Cobra, one of the 23 special beasts of Lo Po Bia Family which was controlled by the 8th son of the Lo Po Bia Family Head. Dowon managed to slow down the giant cobra with her Flower Garden skill before Cha finally came to their aid along with Toro and one other member.

The 8th son then revealed his real intention before of all members of the Hidden Grove team that were present at the time, stating that he was sent to deliver a special message to Dowon that she had to surrender to be sealed at the Wall of Peaceful Coexistence. After hearing the message, the team decided to end the fight with the snake and returns to its warship. In the meeting room, all members of the Hidden Grove team are gathered to hear Dowon's opinion, all of them are present, except Cha. But it turns out Cha waited on the outside of the meeting room. In a teary goodbye with Dowon, Cha finally confessed his hidden feelings for Dowon, by asking if he could ask her out after she got unsealed. After Dowon was sealed, Cha was deeply saddened. He left the team and went to go on a rampage, killing several allies of the Zahard Empire before requesting to be sealed himself.

Dowon (Arc)
After he was unsealed, Cha sees Toro die in front of him as the price for the seal key. Later, Cha interrupts the fight between the 5th Army Corp and the Canines with an energy blast directed straight to Lo Po Bia Yasratcha. Cha remembers the past event before he was sealed away that a mysterious man told him to sealed himself away in order to see Dowon again in the future. The man also tells Cha he will meet a special boy from a noble bloodline that can change the Tower.

The Nest (Arc)
Cha accepts the apology of Kal Rahim and insists him to stop bowing before him as he understand the situation. He tried to persuade FUG Elder Khel Hellam who was hesitant and won't act to fight against Zahard's Army to participate in the war, but the Elder refuse to participate and said that his participation will be pointless because Zahard can see the future more than him and afraid they might lose because of his reckless strategy. Khel Hellam commented Slayer Candidate Jyu Viole Grace may have the power to turn the tides, but he is currently still too weak for war and said that Viole might have to abandon Ha Jinsung. After hearing what the Elder said, Cha respected his decision and said it's a pity that the Elder refuse to help. Cha stated that he has vowed to serve Baam and will follow him everywhere. One week before going to The Nest, Cha met with Viole and pledge his allegiance to him and reveals all information he knew about the ancient nations and Arlen Grace.
