Woo Ik-Han

Height: 157 cm Woo Ik-Han is a regular human and best friends to Shinwoo, Yuna and Suyi, in addition to Regis, Seira and Rai. He spends most of his free time on his computer. He wears spectacles. A running gag throughout the Manhwa is Ikhan's worry about his relatively short height. Initially, when Regis and Seira joined his class at school, Ikhan showed extreme interest in the new students, which others supposed was Ikhan developing a crush on Seira. However, it is later revealed that Ikhan was rather enraptured by Regis, for Ikhan stated that he always wanted a fellow 'short' friend. Throughout his adventures, Ikhan is seen giving Regis foods and candies that are long and thin (such as Pocky) stating that he and Regis must eat them to grow taller (a pun on the stature of the food). His hacking and computing skills are extremely proficient. He was able to match Tao's speeds when Tao tried to hack into Ikhan's uncle's police databases. He is also the best when it comes to computer games as it is mentioned by Shinwoo that Ikhan defeated him every time. Ikhan also shows to be quite brainy rather than brawny, taking school very seriously compared to Shinwoo. (Source: Noblesse Wikia)

Shin-Woo Han

Han Shin-Woo is a student in Ye Ran High School and is popular because of his excellent martial skills. On the day of Rai's awakening, he happens to meet him on the way to school and gradually becomes close to Rai at school, developing a bond which can be termed as friendship. Eventually he gets involved in many strange fights against people with extra-ordinary powers. Rai and Frankenstein rescue him and others from the mess every time. Later he as well as the others are brainwashed for their own safety and so remember nothing of the strange happenings. Shin-Woo is an energetic and athletic teenager with bright red hair. He is always seen with a bandage over the bridge of his nose. He is actually pretty good looking but not that many people realize it because of his behavior. He is well-known within the city to be skilled in martial arts and feared by gangs. Shin-Woo is often shown sleeping (and drooling) in class and slacking off. Though he is shown as a lazy student, he is also very courageous and would protect his friends at all costs. He often tends to be late for school due to over sleeping. He has liked Yuna for a long time and it is disclosed that he confessed to her in past which led to an embarrassing situation. Since then they have been just good friends although Shin-Woo still has a liking for Yuna. Shin-Woo is also starting to like Seira. Shin-Woo is an amazing Martial Artist excelling in Tae Kwon Do and Hapkido. He is well-known within the city to be skilled in martial arts and is feared by gangs. He is able to match the powers of M-24's Infected, and since then has been getting stronger. Even for normal human parameters, it's been quoted that Shin-Woo possesses an incredible amount of strength, which he has displayed during his multiple battles; including those with the Infected. It's been noted that one of Shin-Woo's most incredible attributes is his speed, shown as he instantly disappeared when he went to aid Yuna right after she yelled for help. Alongside his speed, his agility and reflexes have increased during the progression of the series; to the point he was able to dodge one of Shark's attacks and counterattack at the same time. Shin-Woo's most incredible strength relies in his durability, since he is able to endure attacks that would normally kill a human being; as shown when he took a beating from Shark and was even able to stood up against him one more time right after he threatened to kill his friends.

Tao

Tao (Kor. 타오) is a 24-year-old young man who possesses a genius-level intellect in computer programming and other technological fields. He was one of the less cold-hearted members of the DA-5 group, made by Dr. Iris, and is yet another a modified human. He is currently residing with Takeo and M-21 in Frankenstein's residence and is also working as a security guard in Ye Ran High School. He is "Number One" of the RK-4, or 4 Raiziel Knights, which is a group he formed by himself. Within the RK-4 he is known to be the most charismatic and vocal, actively supporting and leading his collegues.

Frankenstein

Frankenstein (Kor. 프랑켄슈타인) (commonly referred to as chairman by the children) is Rai's devoted servant. He supports Rai whole-heartedly and calls him "Master". He had tried searching for his master after Rai's apparent "disappearance." Frankenstein is the principal/director of Ye Ran High School. He was stunned to find Rai in his school office after Rai had woken up and dressed in his school's uniform. Frankenstein is a very cheerful and loyal person, especially toward his master, but can become quite serious and calculative when the situation calls for it. Although Frankenstein has shown somewhat of a sadistic side during his recurrent battles, like Rai, he is also compassionate towards human beings, especially towards the students in his school. Frankenstein is immensely powerful but some of his powers had been sealed away by Rai due to him misusing them in the past. After 820 years of sealing, Rai has finally taken off the punishment. But whenever Frankenstein gets serious in fighting uses his full power, Rai shows a considerable amount of anxiety.

He has no knowledge whatsoever of the 21st century, and will often become lost and confused especially with regards to modern day technology (such as using a cell phone). He is often used as the manhwa's comic relief with his love of ramen and the errors he makes with technology. He has fallen into a deep slumber for 820 years, and had woken up in an abandoned building in South Korea. After seeing what most of the humans on the streets were wearing, Rai took on the uniform of a student from Ye Ran High School, which is under the administration of Frankenstein, and inadvertently followed the students there.
