### Summary
The climactic one-on-one duel between protagonist Gray Yeon and the series' main antagonist, Donald Na, is underway, serving as the final confrontation of their brutal war. This fight was ignited by Donald's mistaken and vicious assault on Gray's defenseless friend, Eugene. True to form, the small-statured (158 cm) Gray has unleashed his merciless "White Mamba" persona, a calculative fighting style that prioritizes intellect and environmental manipulation over raw strength. Despite Donald's inhuman resilience, Gray has revealed a masterful strategy that has left readers stunned. He has brilliantly exploited a previously unknown weakness: Donald's photosensitivity. By strategically manipulating the area's lighting, Gray has turned Donald's eye condition against him, a move that doubles as direct revenge for the attack on Eugene. This display of genius-level intellect has seemingly secured Gray the upper hand, reinforcing the series' core theme of brains triumphing over brawn. With the Yeongdeungpo Union now shattered and former antagonist Wolf Keum officially allied with the protagonists, all focus rests on this final, strategic showdown, where Gray's meticulous planning may finally overcome an adversary fueled by immense strength and a painful past.
