“I Object to That Trial!” (Episode 21) marks the high-stakes third round of the Hiden-ZAIA showdown, shifting the “Five Jobs Contest” into the courtroom. The episode effectively raises the moral stakes as Aruto grapples with the ethical dilemma of using a human’s life and freedom—a marriage fraud trial—as a “game” for corporate ownership. The introduction of Attorney Bingo, a Humagear lawyer with a built-in lie detector, provides a fascinating look at how AI might disrupt the legal system, especially when pitted against a prosecutor enhanced by ZAIA Spec technology.

The tension peaks when Gai Amatsu’s ruthlessness reaches a new low. After Bingo uses his logic to challenge the prosecution, Gai forcibly scraps him by turning him into a Magia, showing a complete lack of regard for Humagears as anything more than disposable tools. This act of cruelty pushes Aruto to a breaking point, culminating in a visual foreshadowing of the MetalCluster Hopper arc when Aruto’s eyes glow red with uncontrollable rage during battle. While the episode is technically part of a much-debated “filler” arc, its character-driven moments and the mystery of the new Dynamiting Lion Raider keep the momentum moving.
