Boro

Boro (보로) is a D-rank Regular and an experienced level Shinsoo Martial Artist who managed to hold onto his Express Ticket till now. He has two Shinsoo Martial Arts apprentices in Hanool Kang and Felix. He seems to be interested in Jyu Viole Grace unaware that his current ally, Baam is the same person.

History
Boro had already boarded the Hell Express twice in the past. On his first boarding of the Hell Express, Boro encountered FUG by getting on the same train as an unknown Slayer candidate and, thanks to him, Boro had suffered some horrible experiences: little by little, the Slayer candidate killed everyone on the Hell Express until, in the end, there were only five survivors including Boro. The other four were incredibly strong but one ended up dying and the rest forfeited the train. During one of his previous experiences on the Hell Express, Aka Williams was his teammate.

Appearance and Personality
Boro has silver-coloured wavy hair, has a small scar on the bottom left side of his chin, wears a brownish black shirt with black pants and is fair skinned.

Revolution Road
Boro was conversing with his apprentices while they were sitting on the train to Train City when he suddenly noticed a blue-skinned Regular enter into their carriage, who he referred to as a "Ticket Hunter". After telling Hanool Kang to go elsewhere, he eventually engaged the blue-skinned Regular in combat and defeated him with one bisecting blow, killing the Regular. Afterwards, Boro noticed that the Regular had been using Emile prior to dying.

Just then Hanool came in saying that a strange Regular had appeared in the other carriage. Following Hanool into the carriage, Boro encountered Baam who asked if they had any Tickets as he was looking for teammates to enter the tournament. Boro asked Baam what he was talking about and Baam replied using Emile to show Boro the tournament that had been announced. Boro then asked why they should join Baam and he replied that if "they" weren't stopped, everyone aboard the Hell Express would die. Baam continued to explain why "they" needed to be stopped but Boro simply asked who "they" were only to find out that they were a group led by Baam's nemesis Rachel a new D-rank. Boro asked how a D-rank could conquer the train but was told that she was backed by FUG, which surprises him. Boro then agreed to join Baam in exchange for picking the team members; he picked Hanool and the train stewardess and they went back to the previous carriage to retrieve their Tickets. Upon reaching they saw two Regulars standing over Felix's unconscious body; Boro then told Hanool to go and retrieve the Tickets to prove he was worthy to be a Ticket Holder but is embarrassed by how weak he was when he started getting beaten up. Boro asked if it would be alright with teammates as weak as that but Baam replied it would be fine as he would take the FUG Regulars and the other Regulars were for Boro to deal with.

Eventually Felix awakened and asked what was going on with Boro filling her in before telling her she can't come with them due to her injuries, to which she agreed with. The train stewardess commented on this and Boro made fun of her statement causing the stewardess to introduce herself as Hana Yu before detailing her dreams, which Boro put a downer on. The train then arrived at Train City and the group encountered an elevator showing various floors. As they decided which floor to go to, someone suggested the 1F Entrance floor but Boro refused saying an incredible gatekeeper resided there, after which he pressed the button to go to the 2F Residence floor.

They ride the slow elevator upwards and Boro asked Baam whether his friends might have gone to the Entrance floor but he replied that they wouldn't have gone the wrong way, sparking Boro's suspicion. Boro and Baam then discussed Baam's history with FUG and the former asked why the latter would want to bring things up with them, with the latter replying that he had things to finish with them. Eventually they reached the Residence floor and, after seeing so many Regulars waiting around, Boro explained that they were waiting to steal Tickets and enter rooms. Just then a Regular appeared trying to scout them for "Sir Aka" but Boro intervened telling him to stop bothering his teammates. The guy, recognising Boro, politely left. The group then heads to Baam's room but are attacked by a group of Regulars with Baam instantly dispatching them, surprising everyone. Boro noted that the martial arts used looked familiar when Baam's allies come out to greet him.

Inside the room Boro muttered about the residence causing Hwa Ryun to ask him if he had boarded the Hell Express before, which he confirmed that it would be his third time. He then asked Hwa Ryun if she was the one with FUG as he had many questions but she replied that he would have to ask them later as a game was about to begin. After "The Last Seven" game is explained and the Regulars in the residential area begin fighting, Boro wondered what was happening before accusingly asking Hwa Ryun who she was with her coolly replying that she was from FUG and was a Guide. She then explained that the carnage was due to FUG wanting something that was on the train, causing Boro to wonder if they were doing "that thing" again, and finished by saying that FUG would do anything to achieve their goals. Boro then asked if she knew the enemies they would be facing and she replied that she didn't know all of them but some were new D-rank Regulars. Suddenly Ha Yura arrived and both quelled the fighting and ended the game with her presence and offer, which greatly impressed Hana Yu. Boro chewed her out and told her that there were no friends on the Hell Express before then telling Hwa Ryun that they should start talking since the game was now over. Hwa Ryun asked about his previous encounter with FUG and Boro explained his history involving a Slayer candidate leaving something on the train. He finished by saying that although he can't remember much of the experience he was sure the Slayer candidate would return to reclaim what he left.

On the day of the tournament, with Baam's team drawn against Yura's team, Boro shared his dislike of the game but nevertheless he and Hwa Ryun talked tactics and strategy with the rest of their team, with Hwa Ryun highlighting that the deciding factor would be Ha Yura's strength. After stepping on to the field of play, Boro in the position of keeper, the "Crazy Yellow Ball" game is set up. Boro mused that the rules seemed advantageous for their team but noted that Baam was acting weird after meeting Yura and also wondered what Yura was planning considering her formation with her limited number of Tickets. The game finally got underway with Baam's team taking the lead. While the Regulars watching were impressed with Baam's skills, Boro and Rak wondered why he had a blank look on his face. On the next round of the game, Boro watched in surprise as Yura overcame Baam's reverse-flow control and wondered what was going on when Baam lost one of his Tickets to the girl. Boro continued to watch the developing game until Baam finally defeated Yura by separating her from her special suitcase. When Ha Yura suddenly vanished and the truth of the tournament being a trap set so that Yura's allies could steal the Hell Express, the Regulars present on the field of play grouped together to make sense of the situation. After some minor confrontation, Boro quickly led the decision to work together to stop the train from being stolen, which everyone present agreed with. Aka then revealed that there was an unnavigable maze-like emergency exit they could use to catch Yura and, fortunately, Hwa Ryun appeared telling them all that she would guide them through it.

After splitting the Regulars into two teams, one to stay behind to keep the tournament running smoothly and the other to catch Yura and her allies, Boro went with the latter team alongside Aka, Baam, Moontari and Ran as they were led through the maze-like emergency exit by Hwa Ryun. As they are travelling Baam asked Boro what his relationship with Aka was and he answered, with Aka rebuking his answer immediately afterwards. The group soon made it out the maze but with the problem of the elevator being broken, they were left stuck. However, after some smart thinking from Baam, they use the elevator's pathway to make it down to the Entrance floor and, after Aka smashed the door to the Entrance area down, they encountered Ha Yura and her teammate. Giving chase to her across the chasm, Yura suddenly switched Mirotic back on, with the gatekeeper immediately launching an engulfing blast at the Regulars, allowing Yura to escape.

Powers and Abilities
Due to the fact that Boro has managed to retain his Express Ticket for an unspecified amount of time shows that he is no pushover. Boro was able to easily take down a Regular who had managed to kill two previous Ticket holders, further supporting his high level of strength. Boro possesses a blue needle, that he seems proficient with, as well as an Arms Inventory.

Due to his previous trips on the train, Boro is experienced in things concerning the Hell Express and was able to recognise a "Ticket Hunter" as well as possessing knowledge of the high ranking top 10 Ticket holders and their level of power.
