Episode 75: "The Avatar Team is Formed"
Synopsis
Rimuru and his companions have finally obtained their temporary "avatars"—physical vessels used to manifest within the Underground Labyrinth. However, they quickly hit a wall. Using low-level avatars with a complete lack of tactical coordination, they find themselves utterly powerless against the formidable "Team Ryuran." Realizing they need to get serious, Rimuru decides it’s time for some old-fashioned special training to whip his team into shape.

Series Synopsis
After the grand success of the Founding Festival and establishing formal diplomatic ties with nations across the land, the Jura Tempest Federation is finally moving toward its ultimate goal: the creation of a "Human-Monster Shared Prosperity Zone"—a world where humans and monsters can live side-by-side in peace.
Tempest continues to flourish, transcending the boundaries of race and species. However, in the shadows, there are those who view the meteoric rise of the Demon King Rimuru as a threat to the world order. Granbell Rozzo—the former "Hero" and head of the Five Elders of the Rozzo Kingdom—alongside his granddaughter Mariabell, begins to set their schemes in motion. Believing that humanity must be protected through absolute control, the Rozzos are headed for a direct collision with Rimuru.
Meanwhile, in the golden land of El Dorado, the Demon King Leon begins to move toward his own mysterious objectives. With the protector of humanity, the Hero, and the Demon King who rules the world all making their moves, the gears of fate begin to turn. Amidst these intersecting agendas, a certain "Hero" is about to awaken—and Rimuru must once again take up the fight for the sake of the dreams he refuses to surrender.
