Ending Explained – What Happens at the End of Mantis?
Still wondering what the ending of Mantis (2025) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.
The climax of Mantis brings together three former allies—Han‑ul, Jae‑yi, and their old mentor Dokgo—inside the MK ENT headquarters. After the chaos unleashed in Kill Boksoon—the murder of the company’s CEO and his sister—Han‑ul tries to build his own agency, while Dokgo works to resurrect the original organization. Both men enlist Jae‑yi, whose ambition to become the top assassin has always burned fiercely.
Benjamin, the scheming head of JB Entertainment, manipulates events by forging a blood‑stained knife and sending it to Dokgo, making it appear as an invitation to duel from Jae‑yi. Dokgo, believing Jae‑yi is challenging him, orders Han‑ul to eliminate a mutual acquaintance, Bae‑soo, to provoke Jae‑yi into action. Han‑ul fakes Bae‑soo’s death, hoping to keep the peace, but the plan collapses when Bae‑soo reappears and Jae‑yi refuses to withdraw the knife.
With tensions at a breaking point, Han‑ul, following Boksoon’s advice, forwards the knife back to Jae‑yi and calls her to a showdown at the MK ENT headquarters, using the same venue as his own confrontation with Dokgo. He assumes Jae‑yi will side with him against their former master, but her long‑standing resentment toward Dokgo drives her to target both men.
During the three‑way battle, Jae‑yi manages to kill Dokgo, finally avenging the rejection and the years of being kept from her potential. She then turns her blade on Han‑ul, whose attempt to protect her ends in his defeat. In those final moments Jae‑yi is filled with regret, realizing that her relentless drive for supremacy has cost her the friendship she once cherished.
The film closes with Jae‑yi assuming control of MK ENT—and, by implication, JB Entertainment—while delegating the elimination of the treacherous Benjamin to Han‑ul. This act suggests a fragile, professional truce between the two: they remain wary of each other’s motives, yet both stand to benefit from a divided, yet cooperating, underworld. The unresolved fate of Benjamin hints at future power struggles, but for now the ending underscores how ambition, betrayal, and a single blood‑ied knife can reshape an entire killing‑industry empire.
