Gachiakuta episode 4 preview hints at Rudo meeting the other members of the Cleaners

According to the preview synopsis, Gachiakuta episode 4 will continue the events from the previous episode, showing Enjin and others bringing Rudo to the Cleaners' Headquarters to meet the organization's boss, who might know a way to return to the Sphere. However, Rudo discovers that the wandering "boss" is absent.

Since Rudo cannot officially join the Cleaners without the boss's approval, he will be given a chance to showcase his talent as an "apprentice." In other words, Gachiakuta episode 4 preview reveals that Rudo will officially embark on a mission with the fellow Cleaners to hunt down a spotted Trash Beast in the vicinity.

Additionally, the preview images for Gachiakuta episode 4 confirm that the upcoming installment will feature Semiu, the receptionist at the Cleaners' Headquarters. She will use her glasses, i.e, her Vital Instrument, to check Rudo's true essence.

The episode will also introduce other key members of the Cleaners HQ, such as Gris, Follo, and Tomme. It will explore the concept of the Supporters within the Cleaners HQ and reveal their role in the story. Moreover, the official staff has announced the voice actors for these new characters.
