That Time I Got Reincarnated as a Slime Season 4 Episode 3: The Avatar Team Is Formed

The episode opens with the unsettling calm of a snowy night, revealing Mariabell Rozzo, a child whose eyes hold an age far beyond her years. We learn she is a reincarnator, an economic and political puppet master from another world. Her unique skill, 'Greed,' allows her to peer into and twist the desires of others, making her a terrifyingly effective manipulator from infancy. This is not a child; it is a predator in a small package.

Mariabell moves through her ancestral castle, a place heavy with history, to meet her grandfather, Granbell Rozzo. He is a legendary figure who controls the Western Nations from the shadows. Granbell recognizes Mariabell's power, tasking her to continue their family's ambition: absolute control to achieve their vision of peace. Her pledge to him is less about loyalty and more about a shared, sinister purpose.

Deep within the labyrinth, a team of human adventurers encounters what appears to be a fearsome boss team: a towering warrior, a skeleton, and a large slime. The expected battle devolves into farce, with the monsters tripping and splashing incompetently. It is then revealed these "monsters" are the avatars of Rimuru, Veldora, Ramiris, and Milim, arguing vehemently about their spectacular failure. Their lack of coordination, Rimuru notes, renders their impressive forms useless.

Rimuru visits Kurobe's forge, a place of industry and craftsmanship. He requests specialized, aesthetically intimidating equipment for his avatar team, hoping better gear will compensate for their initial fumbles. Kurobe and his smiths accept the challenge with enthusiasm, their dedication to their leader evident. It is a pragmatic approach to a chaotic problem.

The avatar team, now better equipped, enters the upper labyrinth levels to practice. Rimuru takes charge, instructing Veldora, Ramiris, and Milim on coordinated attacks. Though Milim's aggressive tendencies initially disrupt their efforts, they slowly learn to function as a unit, plowing through lesser monsters. Their newfound synergy is tested against a massive spider boss, where they coordinate their ultimate moves to achieve a decisive victory. This is how a group becomes a team.

Their celebrations are cut short by Mjurrmiles, who brings news of 'Team Lightspeed,' elite adventurers rapidly clearing dungeon floors. Rimuru recognizes the threat to the labyrinth's secrets and decides a direct confrontation is necessary. The team prepares for battle, transforming into their enhanced monster avatars, now equipped with Kurobe's masterwork gear. They look formidable, ready to truly play the part of dungeon bosses.

Team Lightspeed enters the toxic swamp of the 49th floor, immediately ambushed by the transformed Milim and Ramiris. The adventurers, once confident, are overwhelmed by the speed and power of their attackers. As they struggle to regroup, Rimuru's Ghost avatar appears, radiating holy energy. He unleashes 'Holy Ray,' a brilliant beam of light that incapacitates the adventurers without killing them. This was a demonstration, not a slaughter.

Back in the control room, the avatar team celebrates their victory with pizza and wine, a jovial scene contrasting with the fate of their opponents. Team Lightspeed, defeated and demoralized, limps away from the labyrinth. Mjurrmiles observes from the shadows, knowing the story of their humiliation will spread, deterring future adventurers. The message is clear: this dungeon is not to be trifled with.

In a secluded mountain castle, Granbell Rozzo meets Yuuki Kagurazaka, discussing Rimuru's growing influence. Granbell fears peace would destabilize his family's control. Mariabell then joins them, revealing her sinister plan: to ensnare Rimuru in a peace treaty at the Council of the West, a trap designed to bind him politically. She demonstrates her 'Greed' skill, showcasing her manipulation of Yuuki's desires. Her eyes glow, cold and absolute.

Unbeknownst to them, Souei has been eavesdropping, hidden outside the high-altitude castle. He witnesses Mariabell's chilling demonstration of power and her detailed trap. Souei realizes that this young girl, with her subtle, absolute power to twist desires, is a threat far greater than any physical foe. His face shows deep concern as he disappears into the night, the weight of his discovery heavy on his shoulders.
