Hwa Ryun/History

Tower of God: Part 1
Hwa Ryun entered the tests on the Second Floor posed as a Regular (a job given to her by FUG) so she could better accomplish her objectives without suspicion. She teamed up with Yung Changsoo and Goon in the Crown Game where she refused to ally with the other teams, instead wiping them all out until she was stopped by Androssi. She then got past Androssi and attacked Rachel (perhaps her objective from the start of the game) and as a result she was wounded in the face by Baam who somehow attacked (or perhaps caused her to be attacked) with Shinsoo despite him not having made a contract with the manager.

After the game she was assigned the Wave Controller Position. Later she is part of Yu Han Sung's plan to "push" Ho into taking some action against Rachel. During the final examination, she is seen passing by Evan causing him to have a shocked expression, making one wonder how Evan knows her. After the final examination, in a flashback to before the Crown Game, she is revealed by Yu Han Sung to be a Guide and told to assist Rachel. After the final examination at night, she asked Rachel: "How is it? The feeling of having walked this path?". She apparently knew Baam was still alive and left her for the boy.

Tower of God: Part 2 - The Return of the Prince
She was seen in Part II in a non-conversational flashback (with purposefully empty speech bubbles) of Viole when he was faced with Wangnan begging him to help and even the odds against Lurker.

FUG
Viole went to meet her on the 21st Floor, at a karaoke box which was being extorted for money by a Viole impersonator. Hwa Ryun provoked the Viole impersonator, having fun with the situation. Viole easily took care of them. Yihwa burst in, thinking that Viole was causing trouble. Ha Jinsung entered the scene and was confused about the additional person to their FUG meeting. Yihwa attempted to attack them for being FUG, so Viole knocked her out in order to prevent her from getting herself killed. They all ended up going to Viole's house where they introduced themselves to Viole's team. Eventually, each of them made their own excuses to leave until it was just Wangnan and Hwa Ryun. Hwa Ryun revealed that Viole was an Irregular who was being threatened into doing what FUG wanted. Wangnan was outraged by this and resolved to help Viole.

Epilogue, Path
After the Flower of Zygaena test, Hwa Ryun easily manipulated Yihwa into helping Viole by saying that an elite would attempt to correct her family's wrongs. Wangnan later approached her for guidance, knowing that she was a Guide. He realised that she told him that Viole was an Irregular because he would be able to reconnect Viole to his friends. Hwa Ryun made a remark that implied that his motives could be altruistic or selfish, calling him the "Prince of the Red Light District". She told him that if he wanted to reunite Viole with his friends, they must climb to the 30th Floor and participate in the Workshop Battle.

Tower of God: Part 2 - The Workshop Battle
Before the Workshop Battle, Hwa Ryun traded places with Yuto to become part of FUG's team.

Archimedes
Here, it is revealed that Hwa Ryun told Rak Koon's location before the Hand of Arlen incident, along with the truth about Viole.

One Shot, One Opportunity
During the One Shot, One Opportunity test, Hwa Ryun confronted Leesoo and Vespa. While she was fighting them, Vespa managed to distract her and Leesoo took the opportunity to attack her with his weapon. Viole then showed up to help her. In order to prevent Leesoo from recognizing him, he tore off a part of Hwa Ryun's black robe (we can see her blushing in the background). Later, Hwa Ryun attempted to assist Viole in his fight against Amigochaz, Vespa and Leesoo. Vespa got annoyed and engaged her in combat. Meanwhile, Viole was taken aback after seeing the amount of progress made by Amigochaz. Vespa took advantage of his momentary surprise and attempted to attack him. Hwa Ryun jumped in the way, being stung by Vespa's weapon. As a result, she was poisoned. In the end, she was saved by Viole, who retrieved Vespa's honey jar, which contained the antidote for the poison.

Summoning
When Viole was taken in the Thorn chamber, she guided his friends to summon him and save him from being molten. She helped her side of FUG, by using the other side of FUG's plans against them, so that Viole acquired the Thorn.

Closure
Unfortunately, Hwa Ryun was taken hostage by Reflejo and used in his fight with Viole. Using the White Heavenly Mirror Koon saved her.

Epilogue
After the events of the Workshop Battle, she was seen sat in a room. She had pre-emptively known that Baam would ask her for her help, which Koon noticed. After Koon agreed to the deal, she offered her help and told them of the Hell Express on the 35th Floor.

Prologue
She called all of Tangsooyook to the meeting room to discuss the Hell Express and everything regarding it. Afterwards, she suggested that the team splits away from Viole so that everyone can strengthen without relying on Viole, to which Wangnan and Koon agree upon. As the team left Hwa Ryun noted to Koon that he now had more time and space to hunt down Rachel but he retorted that Hwa Ryun was also his enemy before leaving.

Revolution Road
She appeared from her room, with Rak, on the Residence floor and greeted Viole and his allies. Once inside their room, Boro asked her if she was the one affiliated with FUG as he had many questions but Hwa Ryun replied that she would answer his questions later as a game was about to begin. They watched on as the game to decide the last seven Regulars commenced and Boro accusingly asked her who she was and Hwa Ryun replied that she was with FUG and also a Guide before explaining that all the carnage was due to FUG wanting something on the train and they would do anything to achieve their goals. Then, after Ha Yura arrived and ended the fighting and game with her presence, Boro told Hwa Ryun that they should talk and she agreed.

The next day when the tournament began Hwa Ryun and Boro talked tactics with the team and told them to be most wary of Ha Yura. Hwa Ryun then watched the game, "Crazy Yellow Ball" from above on the sides. During the game, Koon Ran and Novick came up to her and, after initially being suspicious of why she was there, they discussed Viole's impending victory with the skills he possessed. Then, after the two left, Hwa Ryun witnessed Viole overcome Ha Yura by partially using some of the Thorn's power, something which she called pathetic. After finding out that the tournament had been a trap and after the Regulars involved had figured out a way to catch Ha Yura, Hwa Ryun appeared and told them all that she would guide them through the emergency exit maze.

Using her power as a Guide to lead the Regulars through the maze, Hwa Ryun helped to navigate both Beta and Edin Dan as well as her own group through the maze and eventually they managed to get out. However after being told the elevators had been broken they were left in a pickle. Fortunately, Viole came up with a plan to reach the Entrance floor anyway and the group soon caught up with Ha Yura in the guardian's room. As they all attempted to catch Ha Yura, the girl used a remote to turn Mirotic back on allowing her and her teammate to escape.

Hwa Ryun then used her power as a Guide to show Viole a path past Mirotic, which the latter took allowing them to eventually catch up to Yura and her teammate. The teammate then challenged them to allow Yura to escape again but Boro arrived and took him on instead, allowing Viole and Hwa Ryun to catch Yura once more. Viole shouted her down until Daniel Hatchid arrived and provoked Viole with his introduction. After Daniel challenged Baam to a "match", Yura fled up the stairs with Hwa Ryun chasing after her. Hwa Ryun noted that she wouldn't be able to catch up just by chasing her and decided to try something else. By using her staff as a foothold, she leaped across and cut Yura off but, before she could engage Yura, Angel appeared and took her on. After Angel dropped a bombshell about Emile's power, Hwa Ryun tried to put up a fight but she was greatly overwhelmed by Angel's metalfish and severely beaten. However, instead of killing her straight away, Angel decided to take Hwa Ryun as a hostage and she was subsequently taken on to the Train with them.

Hoaqin
Inside the train, Hwa Ryun was constantly being kept under supervision. She was then called to help Rachel's group when they couldn't solve the maths puzzle that was preventing their continuation. With Hwa Ryun solving the puzzle easily, the group moved into the room where they encountered Bloomer guardian but, with Hwa Ryun's guidance, they defeated the guardian and opened the door sealing Hoaqin's first part.

After Hoaqin's introduction, they all left the room and ran into Yeon Yihwa and Ja Wangnan. Hwa Ryun told them to flee but instead, they two decided to attack causing Wangnan to almost get his hand severed. The two were then captured alongside Hwa Ryun where they then witnessed Rachel's group completing the 36th Floor stage test of the Hell Train.

Wooden Horse
As the train was heading towards Wooden Horse station, Hwa Ryun asked Rachel why she was allowing her freedom. Rachel replied that Hwa Ryun was not a threat as long as she had Emile and explained her goal on the Hell Train. After being teleported by the conductor of the train, she internally identified him as Pedro the Death Eye, and questioned his motivations. She was also shown to briefly display annoyance when Viole noticed her some time after she actually appeared next to him.

A Month
After reuniting with Viole she announced to the team that from that moment on Viole would be taking care of all of the battles himself. When met with opposition to the idea, she harshly lectured Viole on how his actions once meeting Rachel had put everybody else in danger, and told him that acting so selfishly made him no different from Rachel. Though quite brutal, Viole seemed to take those words to heart.

After Viole was taken by the "god" of guardians, she had a brief conversation with Koon, wondering why he was so calm despite Viole's situation. He replied that he had no choice but to accept it, and stated that if something went wrong he would always regret leaving Viole in her hands.

After three weeks, Viole returned to the group and they eventually made it to the 4th stage just in time.

The Dallar Show
Hwa Ryun observed Koon effortlessly win in the first round game of the Dallar Show. In the second round game, she was partnered with Koon and Hong Danhwa in the Sweetfish Team.

Yuri Jahad
After the events of the Dallar Show Evan Edrok approached Hwa Ryun and said they both need to chat, before discerning that she was acting as Baam's Guide. Hwa Ryun confirmed that and Evan asked for whose sake she was doing it for. Hwa Ryun responded by saying she wasn't doing it for anyone's sake, as Baam was walking down a completely new path that no-one had ever walked, and all choices would be made by him.

Shortly after, Hwa Ryun met with Ja Wangnan who blamed himself for not catching Cassano and allowing Vicente to be absorbed into Hoaqin. The Guide recalled that as long Wangnan remained on the Hell Train another opportunity would arise for him. However, such an opportunity would provoke another crisis that would cost him the life of one of his teammates.

The 'Name Hunt' Station
