Solo Leveling

Tae-Sik is one of the characters in Solo Leveling who combines several roles: an inspector of the Surveillance Group, a B-rank hunter, and an assassin. He was first introduced while visiting Jin-Woo in the hospital and later returned in the Prisoner Arc. Kang considers hunters superior to ordinary people and is driven by bloodlust coupled with financial gain. As an assassin, he is also skilled in lying but is able to recognize the strength of an opponent.

When first introduced, Jin-Cheol was the Chief Inspector of the Korea Hunters' Association's Surveillance Team. After the dungeon-within-a-dungeon incident, he was the one who visited Jin-Woo in the hospital. The purpose of the visit was to find out the details of what happened and whether the protagonist had undergone a re-awakening. Woo is a professional by nature, rarely showing emotions, but is capable of showing character.

A hunter and long-time friend of Jin-Woo and Joo-Hee. He is one of the survivors of the double dungeon incident, where he was ready to sacrifice his own life to save the others. After the incident, he lost his arm, but did not lose heart. By nature, Chi-Yul prefers to follow a clear plan when passing dungeons, but is also capable of taking risks. The man is also open to the opinions of his comrades and tries not to pressure them in matters of choice.

Han Song-Yi is a close friend of Jin-Ah's who has undergone her own personal transformation. She originally dropped out of school to earn "easy" money through hunting raids. Wanting to prove her wrong, Jin-Woo took her on one of the White Tiger's dungeon clearings, but the entire group ends up trapped in the Blood Gate. After a close call, Song-Yi reconsidered her views and decided to continue her education, and also developed a liking for the protagonist who saved her life.

Park Hee-Jin is a young hunter from the White Tiger Guild, first fully introduced in the Blood Gate Arc. Finding herself in such a dangerous situation, the girl became one of the few survivors due to her attentiveness and prudence. Hee-Jin immediately realized that Jin-Woo was clearly not an E-rank and chose to join his group, and over the course of the story, she revealed herself as a caring comrade and loyal guildmate who sincerely cares about her organization.

Ju-Hee is a B-rank healer hunter who was afraid to go into dungeons higher than C rank. The girl has known Jin-Woo for quite some time and often healed him during raids. She is one of the hunters who survived the double dungeon incident and suffered psychological trauma after these events. By nature, she is a compassionate and friendly person who became close to the protagonist during their raids and was very worried about him.

The main character's cheerful and loving younger sister. Jin-A is genuinely worried about her brother and says outright that if he gets seriously injured and can't go into the dungeons, she will quit school and find a job. Jin-Woo basically raised her when their mother fell into a coma and their father disappeared into the dungeon. The girl is truly grateful to him for his care and tries to reciprocate.

A young hunter and Jin Woo's loyal friend. Despite not being the strongest hunter, he supports Jin Woo and often helps him in his quests.

The president of the South Korean Hunters Association, he is an important ally for Jin Woo and plays a key role in supporting hunters.

An S-rank Hunter and the leader of the Hunters Guild. He is known for his fire magic and is considered one of the strongest Hunters in South Korea.

An S-rank Hunter and the leader of the Baekho Guild. He has the ability to transform into a tiger.

One of the strongest hunters in Korea, Hae-In became an S-rank approximately two years before the main story. Due to her sensitivity to mana, Cha could sense a strong odor from her colleagues and monsters, with the only exception being Jin-Woo. As a hunter, she is competent and diligent, trying to develop her own abilities through training and took the position of vice-guildmaster of the Hunter's Guild. She is a perceptive person, but also easily confused.

Seong Jin-Woo (Seong Jin-woo, Seong Jin-woo) is the protagonist of Solo Leveling Up, who managed to significantly increase his strength after becoming a System player. At the beginning of the story, the young man was known as the "Weakest Weapon of Humanity" and remained in the ranks of hunters only to pay his mother's hospital bills and provide for his younger sister. By nature, Jin-Woo is a kind and caring person who, having become stronger, did not boast about his achievements and first of all thought about his family.
