The Strongest Tank's Labyrinth Raids -A Tank with a Rare 9999 Resistance Skill Got Kicked from the Hero's Party : Episode 4

Rud joins the Hero’s Party in raiding labyrinths, hoping to find a legendary treasure capable of curing his ailing sister. After being blamed for a failed expedition and expelled from the group, he begins the journey home. Along the way, an unexpected encounter starts to reveal the true nature of his mysterious abilities.

Returning to Avancia with Luna, Rud reunites with his beloved sister, Manicia, and begins settling back into life at home. Although Luna remains uneasy around others, the siblings’ warm welcome gradually helps her lower her guard and consider a new place for herself.

Manicia worries that her illness is preventing Rud from pursuing his own future, while Nin arrives in Avancia with troubling news about the Hero’s Party. When a powerful monster threatens the town’s orchard, Rud must use his newly discovered abilities to protect those closest to him.

Determined to save Manicia and protect Avancia, Rud leads his companions into the newly discovered labyrinth. As the group battles through increasingly dangerous monsters and advances toward its deepest level, Rud must confront the risks of involving his friends in a quest driven by his own deeply personal dream.

With Manicia’s condition improving, Rud is asked by Marius to take control of the newly conquered labyrinth. Reluctantly accepting the responsibility, he begins learning how to manage it while the growing demands on his clan—and two unexpected invitations—present new decisions about their future.

While preparing to raid the Keild Labyrinth, Rud learns about Lilia and Lily’s painful past. Inside, Lily steps forward to command the party, leaving her protective sister conflicted by the change. As the expedition advances, Marius shares a surprising truth that could alter the group’s journey.

As Lily grows more confident, Lilia struggles with the fear that her sister no longer needs her. Rud helps her regain perspective before the party returns to the Keild Labyrinth, where a dark skeleton’s unusual attack forces Lilia to confront painful memories from her past.

At the deepest level of the Keild Labyrinth, Rud’s party confronts Amon Sloth, a Demon King whose powerful wind magic and extraordinary speed overwhelm them. Forced to rely on careful coordination and the trust they have built, the group searches for a way to withstand her relentless assault.

When a wounded girl arrives seeking help, Rud discovers a group of homunculi who fled a neighbouring kingdom under pursuit by combat models. After intervening in the conflict, he offers the refugees protection in Avancia, but their arrival leaves Luna worried that her own hidden identity may finally be exposed.

Aware that Demon King Greed poses a growing threat, Rud intensifies his training inside the labyrinth. Meanwhile, the homunculi complete a public bathhouse, helping them earn Avancia’s acceptance. Just as peace begins to settle over the town, alarming news arrives that a vast horde of monsters is approaching.

At the lowest level of the labyrinth, Rud and his companions confront Greed, the mastermind behind the illegal homunculi. Enraged by his cruel experiments, the party prepares to stop him, but Greed undergoes a terrifying transformation and unleashes overwhelming demonic power that pushes Rud’s defences and the group’s resolve to their limits.
