Yu Ijin

•Martial Arts>•MCMAP•Silat(Not Confirm)•Unknown

***Yu*** **Ijin** is the central protagonist of the *Mercenary Enrollment* (alternative title: Teenage Mercenary, Ipak Yongbyeong). A gifted young mercenary and survivor of a plane crash, he opens the story when he returns to Korea after a decade to reunite with his family. His sole intent is to keep a low profile, but this is increasingly thwarted by school bullies, kidnappers and international criminals.

Ijin's story drives home multiple overarching themes in the manhwa, such as defending the weak and treasuring relationships. He has taken on the role of the protector multiple times, having protected his sister Yu Dayun from bullies, Cha Dusik from other gangsters, 032 from other mercenaries etc. He has also stood up for Shin Yuna, Shin Jiyeh and Cha Seoha. The people whom he serves are mostly relations of some sort, or individuals vulnerable to abuse of authority; these actions are taken on behalf of his personal values, and further emphasize the manhwa's objectives.

## Appearance

Yu Ijin is a tall, grey haired boy in his teens. Although he is portrayed with a slender build, he is at least as strong as soldiers of the Special Military Force. He currently outclasses everyone in terms of combat skills introduced in the story except 002, who taught him how to fight and he seems evenly matched with. In his mercenary days, he wore olive fatigues and a shemagh to conceal his face. He is mainly seen wearing school attire, casual wear and his formal suit (after becoming a bodyguard trainee). When angry, his face is expressionless but he is portrayed with reddish irises of the eyes and a blue aura surrounds him. Ijin's most powerful features is his EYES. When ever Ijin is really happy or peaceful or worried his eyes are closed or hidden from view. When he is shown shirtless, his torso and arms is covered in scars from knife and bullet wounds.

## Personality

Due to gruelling training as a mercenary, Ijin is a composed and reserved individual who never panics in the face of danger, and is very astute and decisive- qualities that can be prominently seen in combat. He gradually explores the concepts of love and affection after reuniting and spending time with his family, which he begins to value above anything else. After he begins to attend high school, Ijin is able to make friends and frequently joins them to play Legends of League (MOBA) at the internet cafe. He is noted to be inept at video games, but is unusually adept at actual combat.

He is the strong silent type, who speaks less and listens more. He almost never shows his emotions when fighting and there are countless times when he is shown to be simply listening and thinking about things he sees or hears (speech balloon with lots of dots are shown numerous times in every chapter)

He is emotionally stable, and has only shown extreme distress when (1) when he remembers his plane crash with his parents at 9 years age, and (2) when he was ordered to kill a mother and young girl while working as a mercenary (it is not known if he actually did kill these innocent people).

**CHARACTER QUIRKS AND CAPABILITIES**

Ijin is depicted as an ideal fighter: good looking, physically strong, well-versed in battle tactics and strategy planning (including espionage), extremely intelligent for his age, and possessing a code of honor. He is very gifted in IQ (intelligence quotient) and EQ (emotional quotient), though he experienced some awkwardness in the beginning of the manhwa due to his initial excessive defensiveness (a problem that Sukjoo sometimes shares). His code of honor includes repaying his debts and kindness done towards him, as well as protecting the weak if he sees them subject to mistreatment. He has almost no school issues or family issues and hides his battlefield memories quite well because he wants a normal life with family. When required to do settle professional matters, however, he is capable of being incredibly calculated, on par with any highly trained adult far older than he is. This includes Lt. Hamchan, who rescued him from the battlefield, and his grandfather, who remains uninformed of his background.

**CHARACTER FLAWS**

Although Ijin is mostly shown in ideal manner, here are times where he is shown with faults as well. In earlier chapters, his behavior towards Shin Yuna and Koh Sukjoo was superficial and detached. In addition, he seemingly is averse to romantic love since it would hinder his goal of protecting his family members. For this reason he tries to avoid becoming close to Shin Yuna and purposely kept her at a distance. However, latest chapters show there may be a blossoming romance between them.

**ANONYMITY**

Ijin is extremely conscious of his own privacy, and for his family and school life (he was very rude and blunt to Yuna because she had ordered Sukjoo to check up on his background). As he is secretive, he replies in almost terse statements to questions. He also declines invitations to dinners where he feels he might be indebted to people. Sukjoo was the first person to be invited by him personally to eat together, as appreciation for having helped him. He takes interest in people who are willing to respect his decision. Ijin hate people who keep forced him or doesnt listen to him. He willing to share his secret if the person doesn't questioning his explanation, just like Sukjoo, who would accept without doubt his hint about his past and 006, simply taking it for what it was,

Despite being so strong he does not want to indulge in becoming a "bully" or a "boss" in school but rather wants to blend peacefully. Intelligent people usually hide their emotional scars and it's true for Ijin also. At a young age he has probably experience being abandoned, manipulated, trapped or controlled by persons in power or wealth. It seemed that he had rescued many people during his mercenary days but the only one to rescue him in turn and help him reunite with his own family is Lt. Hamchan, hence Ijin is especially close to him. Ijin has a strong sense of being "wronged" and his thoughts at the end of Chapter 29 are extremely influential in conveying this. Also there one single panel (Chapter 44) in which ijin had protected a lady Shin Jihie at almost the cost of his life and she walks away without being enthusiastic in her thanks. The panel shows subtle but noticeably annoyed Ijin.

Interestingly, politicians like the Senator Kim and rich businessmen are not shown in a particularly good light in the manga, while military is portrayed more favorably. Gang bosses are also not shown very nicely except one person Cha Dusik who is "somewhat" friendly with Ijin. However, Ijin on the other hand kept Cha Dusik at a arms-length distance (until very recently), despite that Ijin had to borrow Cha's motor-bike several times to, including to rescue his sister Yu Dayun (chapter 17) and even to battle another mercenary 006.

This is why he kept aloof from Cha Dusik because Cha Dusik used to be close to Senator Kim. Also, Ijin seems to be very hesitant and distrustful of the Shin family in the beginning including Shin Yuna, Shin Jihie and even the grandfather of Shin family. His attitude changes when he realizes that Shin Yuna’s father had met him during mercenary days and was a kind man who treated him like a son. Even when Ijin starts work part-time as a body-guard for Shin Jihie, he appears to be aloof initially

Ijin’s unconcerned behaviour towards a cute, younger, naive rash mercenary comrade 032 (17 years old, hence 2 years younger than Ijin) who was bleeding from gunshot wounds while Ijin was calmly offering him food to eat. This is in sharp contrast to how he decides to go out of his way to protect Lt. Hamchan at the cost of his own life “because he did not wish to live with regret of not having helped”. 032 was actually depressed when Ijin was rumored to die. But Ijin later on went out of his way to rescue 032 and showed that he does really care about people so much he is even willing to risk his life.

## History

When Ijin was nine, he and his parents were involved in a plane crash. Although Ijin survived, he was orphaned and was stranded from his remaining family. On top of that, he also lost his memories about his past. Eventually he was taken in by an unnamed group. In chapter 94, we find out that this unnamed group (called the Camp) is an special experimental unit under Iron (an global private military corporation). In this experimental unit 1000 people were put under extreme extreme training, which only 40 people managed to survive in the end. These people were called “the numbers”. Ijin underwent harsh training together with the other numbers and he worked as a top class mercenary for about five years, serving in the harshest battlefields across the world. At some point, he defected from the camp, when he was ordered to kill a mother and a young girl while working as a mercenary. At that time his memory also started to return. In chapter 92, it was said that the camp suffered near annihilation when they tried to kill Ijin for defecting, but rumours spread that he died during that night. Nevertheless, he was still alive and continued to work as a mercenary under an different alias (Code name “JIN”) for about 5 years.

Later, during a rescue mission, he saved a RoK major named Kang Hamchan, his team and a doctor named Andrian Ken. Kang Hamchan traced Ijin's family and helped him retire. Ijin underwent a six month orientation from Major Kang to help him adjust to civilian life. He's currently living with his grandfather and his sister in Seoul. Aside from attending Shinan high school, Ijin works as a part time bodyguard at the SW group's security team, along with his fellow classmate Koh Sukjoo.

In Chapter 1, we are clearly told by Ijin himself, that he was 9 years old when he suffered a plane crash and through his sister, Dayun we learn that he has returned home after 10 years.

In the same Chapter 1, when discussing with Lt. Hamchan, Ijin also tells he was on the battlefield as a mercenary for 10 years.

Plus, also in Chapter 1, Ijin had a six month orientation with Lt. Hamchan before reuniting with his family and also forged but official documents were being created by the government to give him suitable cover to reintegrate normally into school and family life (also in those 6 months Lt. Hamschan MUST have been possibly MONITORING if Ijin has any serious psychological issues that could cause problems for his smooth integration).

In Chapter 20, Ijin’s fellow mercenaries call him JIN. Then, in Chapter 24 , Shin Yuna’s grandfather mentions that Shin Yuna’s father Shin Ingook was rescued by Ijin three years earlier from the date of Ijin’s school meeting with Shin Yuna’s grandfather. This fact is further confirmed in Chapter 26, (when Ijin is selected as best performer in SW training). We learn from Shin Yuna’s grandfather that he was identified with code name” Jin” when he rescued Shin Ingook.

In Chapter 10, Ijin hacked Cha Dusik's computer (a leading crime gang boss with a good heart).

In Chapter 31, Head Mercenary of the camp "Mad Dog" remembers being wounded by Ijin (blinding him in one eye). We also know he is the head mercenary because in Chapter 55, his face is shown when 032 is referring to him with Ijin.

In Chapter 50, a female mercenary named Krasilla states that the mercenary JIN disappeared about 6 months ago.

In Chapter 52, Ijin has a nightmare from remembering his trauma of killing a young girl and her mother, during a mission.

In Chapter 61, Ijin correctly understands the complicated financial transactions between 2 companies collaborating with each other to pressurize Cha Seoha to work for them (thus avoiding bankruptcy) while even though being older, Cha Seoha does not realize this.

In Chapter 72, Ijin seems to understand Lewis Bailey’s (an American’s) discussion with Yuna, hence rescues Yuna from an embarrassing situation. We also know that Yuna and Sukjoo spent time in the USA so they can understand English.

In chapter 93, Lt Hamchan mentions that Ijin was 16 years old when they first met.

In chapter 94-95, Ijin states that he only subdued the 26 numbers that were after him when he defected, yet he never killed them. Therefore, someone else must have killed them and blamed their death’s on Ijin. This was probably done by the chef of the Iron corporation since he also tried to kill 005 by sending an group of mercenaries, yet failed regardless duo to Ijin and 005’s collaboration.

In chapter 96, Ijin states that he was a mercenary for 5 years before returning to Korea.

In chapter 97, it was revealed that 5 years prior to being a mercenary Ijin was part of the camp where he underwent hellish training together with the other numbers.

In chapter 98, Ijin became in charge of the special unit of numbers and received the name “001”.

So from information above, we add the situation up and arrive at the following conclusion

a) Ijin is ATLEAST capable of understanding two (2) languages Korean and English and probably one other language of the foreign country where he was raised as a orphan mercenary.. Since countries where English is normally spoken are mostly developed countries with good security and absence of war, such mercenary camps using " ORPHAN child soldiers" are unlikely to be operating from inside a developed country (Infact ORPHANS as CHILD SOLDIERS are used in war affected countries, so this point is realistic)

b) Ijin was ATLEAST 15.5 or 16 years old when he deserted the Camp and operated as JIN, till he was rescued by Lt Hamchan at 18.5 or 19 years. When rescued by Lt Hamchan, and with 6 months orientation, he is now probably already 19 or 19.5 years old. So Ijin picked up all his battle skills (additional language ability, computer hacking skills, physical fighting and tactical analysis, leadership skills, sophisticated financial knowledge) in 6 years from age of 9 onwards till 15-16 years, when he felt confident enough to desert the camp, (even at that age he was an better fighter than the head mercenary at the camp "Mad Dog", having blinded him in one eye) as well as, kept his new identity so skillfully a secret that the camp did not suspect that "JIN" and "001" are actually the same person. Also, during this period of 9-16 years of age, he had also killed a mother and young daughter which deeply traumatized him and made him attack the Head Mercenary, as well, as abandon his camp. Ijin must have already killed countless people but killing an innocent mother and her daughter was VERY DISTURBING for him.

## Relationships

### **Yu Dayun** **(Younger Sister)**

Ijin is very protective of his younger sister. When he discovered that she was being abused and bullied, Ijin thrashed the bullies and utterly destroyed the reputation of the main culprits by anonymously leaking footage to the media.

After being rescued by Ijin in the first chapter, Kang helped him retire from the battlefield, treating him as his younger brother. He reunited Ijin with his biological family and trained him to properly adjust to civilian life. Even after leaving his care, Ijin maintains contact with his benefactor. It was Kang Hamchan who heavily classified Ijin's background information, to protect him from suspicion. Interestingly, his fiancee, Shin Jiyeh is Ijin's boss at SW corp.

Kang's military team also saw Ijin like a younger brother and always have his back.

Lt. Kang denied a request to check into Ijin's background from his fiancé, Shin Jiyeh.

### **Cha Dusik**

One of the major mafia bosses in Seoul. Cha Dusik was hired by senator Kim Inbae to eliminate Yu Ijin. After being defeated by Ijin, Cha Dusik views him as a worthy opponent. Later, he is surprised when Ijin is able to hack into his system to access incriminating evidence about Kim Inbae's political scandals, and is further surprised when Ijin uses it to secretly destroy the career of the family. Gradually, Cha Dusik and his subordinates become friends with Ijin after the latter saves them from a rival gang.

### **Koh Sukjoo**

They started of in rough terms because Sukjoo was very suspicious of him, checking his background and falsified information. Sukjoo assumed he was in some way, after Yuna. But after Yuna gets kidnapped along with Dayun, both Ijin and Sukjoo had no choice but to work together. After that incident the tension died down and they become trusted friends. Sukjoo drops his suspicions, and is impressed by Ijin's superior combat abilities. Later, the two of them work as part time bodyguards at the SW group, although in different teams. He was the first person to be invited to eat with Ijin himself as a thanks. With the passage of the series, Ijin and Sukjoo develop a close friendship, seem likes Ijin easily talk to Sukjoo and even give him a hint about his past secret. Sukjoo is one of the few people Ijin fully trust, and has been a great ally and partner when it comes to face enemies in several times.

### **Shin Yuna**

The heiress of SW group, Shin Yuna attends the same class as Sukjoo and Ijin. Initially, Yuna and Sukjoo were suspicious of Ijin due to his fake background information, but changed their minds after he rescued Yuna and Dayun from kidnappers.

She tried to investigate Yu Ijin after learning of his role in saving Yuna from the kidnappers, although she was shocked that his background was heavily classified by the government. Later, Ijin begins to train with the bodyguards of the SW group. Impressed with his superior abilities, Shin Jiyeh includes him in her personal escort group. Ironically, Shin Jiyeh's fiancee, Lt. Kang Hamchan, was the one responsible for classifying Ijin's information. Shin Jiyeh favours Ijin for his top notch skills as a bodyguard, although she worries about him due to his young age. She is amused to learn that Ijin and her fiance are acquainted with one other, although she doesn't know the exact details about it.

### **Cha Seoha**

A young TV celebrity who was being harassed by a stalker. To give Ijin an easy task, Shin Jiyeh assigned him to be Cha Seoha's bodyguard for a while. The actress became comfortable with Ijin and was surprised to learn that he was attending high-school. The next day, Ijin investigated the entire matter- that Cha Seoha's ex-boyfriend, director Ki Donggeun was the culprit, who tried to blackmail her into renewing her contract with his company. After cleaning the mess, Ijin requests Shin Jiyeh to recruit Cha Seoha into her entertainment company, with a better contract. To express her gratitude, Cha Seoha visits Yu Dayun and personally wished her on her birthday.

### **SW Bodyguards**

The first time Ijin went to work in SW he had a rocky start with the bodyguards since he defeated all of them sparring and in every exercise done in their training. However, with time Ijin manages to adaptate more with his fellow bodyguards by holding back his abilities. Eventually, Ijin develops a good relationship with all of them despite not talking too much with them. SW bodyguards now consider Ijin as one of them or even as their protegee, fully trusting him when it comes to face other opponents. When Lewin Bailey mentioned the offer he made to Ijin all bodyguards were atonished believing that "their Ijin" would be taken away.

As result of the traumatic training experience all the Numbers have a hard feeling of comradery and brotherhood to each other, on the most recents chapters will be revealed that the Numbers have a rule not to kill each others; however, as Ijin recovers his memories and decides to leave the Camp, all the Numbers feel betrayed and will try to kill Ijin at least once.
