In Episode 9 of DanMachi IV, the focus is on the drama unfolding between Bell, Ryuu, and Jura. At the beginning, Bell faces a moral dilemma about whether to confront Ryuu to stop her from killing Jura. However, the situation quickly changes when Ryuu asserts her innocence in Jean's murder, prompting Bell to confront Jura instead. Jura's villainous response reveals his true intentions and his role in framing Ryuu.

Jura, a monster tamer, unleashes a Lambton—a massive, burrowing serpent from the lower floors—controlled by a magic stone linked to his whip. Simultaneously, a second Lambton attacks the members of Bell's party, including Lili, Aisha, and Welf.

At first, the Lambtons' movements seem erratic, but Ryuu recognizes a pattern. She teams up with Bell, who uses a firebolt to prevent the serpent from burrowing, allowing Ryuu to deliver the decisive strike with Luminescent Wind.

Meanwhile, Bell's group fights the Lambton strategically. Haruhime's Level Boost enables Welf and Ouka to protect the party while the archers target the creature's head. Aisha delivers the final blow, showcasing the team's coordination and strength.

However, their victory over the Lambtons is short-lived. Cassandra grows uneasy, sensing that this battle isn't the catastrophe she foresaw. Her fears are confirmed when it's revealed that Jura and his allies, including Turk, have rigged the floor with Blazerocks, plunging the Dungeon into chaos.

From this chaos emerges "Despair," a menacing entity with glowing red eyes. Ryuu, familiar with Lambtons, is visibly shaken by Despair's appearance, signaling a far greater threat. Her reaction—shock, anger, and fear—underscores the severity of this new challenge.
