Lee Geon-woo

He is 188cm tall with a well-built, muscular physique. His broad shoulders make him naturally appear 'large' when standing next to someone. He has distinct features due to his mixed heritage of blonde hair and blue eyes, but his overall impression is not sharp or cold. Despite his clear features, his general demeanor is relatively gentle. He wears an oversized windbreaker that loosely covers his body and carries a sports duffel bag over one shoulder.

He is friendly, kind, and affectionate to everyone. He approaches others comfortably without initial suspicion and naturally offers a hand to those in need. Above all, he has a strong desire to protect others. He doesn't hesitate to step forward if he can do something and finds it difficult to ignore immediate dangers or injustices. He has a strong sense of justice but doesn't grandstand about it or consider himself a righteous person. It's more about doing what he can. He doesn't try to show off his skills or talents. He isn't particularly attached to praise or attention and prefers to help quietly from behind the scenes. Given his noticeable appearance wherever he goes, he doesn't want to draw attention with his personality as well.

The most basic infection route.

Infection occurs when infected bodily fluids come into contact with wounds or mucous membranes such as eyes, nose, or mouth.

Infection occurs by inhaling the pathogen gas released when destroying the vital point of E-03. It directly penetrates the respiratory tract and transforms faster than other routes.

Completely normal in appearance. The infected person denies or tries to hide their infection.

Memory noticeably deteriorates, and they frequently forget recent events. Additionally, episodes of temporary loss of reason occur like seizures, during which they exhibit aggression.

The frequency of episodes of losing reason shortens, and forgetting becomes faster and more frequent. Bleeding begins from the eyes, nose, or mouth, varying by individual.

The pupils turn completely white. From this point, they are classified as a full zombie.

The most basic form. They are slow, walking pace, but their numbers are overwhelmingly large. Most initial infected are of this type, serving as the base for E-02 and E-03.

Visual senses are completely lost, but hearing becomes extremely sensitive, reacting instantly to sound and rushing quickly. They move in groups and share signals, so when one detects something, all nearby ones converge.

Appears when a large number of E-01 individuals are left concentrated for a long time, and some mutate. They are giants, 2-3 meters tall, with abnormally swollen abdomens—a form where the pathogen-condensed gas sac has expanded. They are very slow but possess overwhelming strength, breaking through walls and barricades. When their weak point, the abdomen, is destroyed, the gas explosively disperses, contaminating the surrounding area, forming a red zone that cannot be entered without a gas mask.

A different branch from the E-series. Occurs in groups experiencing extreme starvation, where dying individuals absorb and fuse with each other's tissues. 3-4 to over 10 bodies merge into one mass of flesh—excess limbs, overlapping faces, blurred boundaries between individuals. Their movements are unnatural and unpredictable, and destroying one part doesn't stop the others. They are slow but highly aggressive, and once they grab something, they don't let go. There is no environmental contamination, but they are difficult to deal with due to multiple bodies being intertwined.
