### Summary
Having just defeated the colossal gatekeeper in Japan, Sung Jinwoo discovered it was merely a prelude to the true power within the S-Rank gate. Inside, he confronts not an immediate enemy, but the imprisoned King of Giants, a being who offers long-awaited answers instead of a battle. This massive figure reveals the cosmic conflict driving the appearance of gates on Earth, explaining that the "Rulers"—angelic beings of immense power—are responsible for the dungeons. They capture and brainwash magical beasts, forcing them to attack humanity in a grand scheme to imbue the planet with mana and prepare it as a battlefield for their ancient war against the "Monarchs." This critical exposition reframes the entire narrative, blurring the lines between good and evil and suggesting the System itself may be a tool of these manipulative Rulers. Amidst this tense revelation, a key character moment unfolds as Jinwoo's ever-loyal shadow knight, Igris, demonstrates his protective nature by shielding Jinwoo's friend, Yoo Jin-Ho, from harm. Now armed with paradigm-shifting knowledge, Jinwoo must navigate a complex web of cosmic entities where the true enemy is no longer clear.
