Representatives from A.I.M.S. sought an audience with the newly appointed president of Hiden Intelligence, intending to question him regarding the recent incident at the amusement park. Their visit was abruptly interrupted by an attack from…

Aruto attempts to persuade a recalcitrant sushi chef to employ a Huma Gear in his establishment, just as Yua arrives, offering an apparent endorsement of Aruto’s proposal.

Aruto and Izu made a delivery of the latest Huma Gear to the renowned manga artist, and both suspected a waning of his creative fire.

Horobi granted Jin permission to pursue one of Zero-One's Progrise Keys, yet he faltered, paralyzed by the sight of a Huma Gear and her father.

Aruto was summoned to address the basketball coach at the school, a consequence of parental complaints.

During the unfolding events of MetsubouJinrai.net's plot to assassinate Yua, Aruto undergoes a medical examination by Nurse Huma Gear.

As Fuwa is hurried towards the operating room, Hiden Intelligence issues a directive: all Huma Gears within hospitals are to be immediately deactivated, a precaution prompted by the emergence of MetsubouJinrai.net.

Hiden Intelligence is backing a television drama with a Huma Gear as its central character. Fuwa discovers that Yaiba was responsible for the leak of the Huma Gear footage.

Under Horobi's influence, Enji's work suffers, disrupting the production schedule for Hiden Intelligence's drama. Meanwhile, Aruto arranges a meeting with the director of ZAIA.

The police discovered Aruto’s hidden laboratory with the arrival of a Huma Gear detective, brought in to assist with the investigation.

The Shining Hopper’s performance was underwhelming, falling short of expectations. Izu bears the complete responsibility for this deficiency.

Following his evening rides, Aruto is visited one day by a pair of representatives from Satellite There, bearing Huma Gear.

Amidst the chaos of A.I.M.S.'s attack on MetsubouJinrai.net, Aruto found himself imparting lessons to Izu and Subaru about the meaning of family.

The final confrontation between Aruto and Jin concluded, and with it, a sense of equilibrium returned to the world.

The president of ZAIA issued a direct challenge to Aruto regarding the acquisition of Hiden Intelligence.

Fuwa charged Yua with tampering with Horobi. Meanwhile, Aruto discovered that ZAIA’s representative had engaged in dishonest practices during the competition.

ZAIA presented Hiden with a new undertaking: the sale of houses. Meanwhile, Fuwa sought out the remaining associate of Horobi.

A smile often appears when a substantial offer is presented during a house sale.

With a single round remaining in the contest, Hiden summons the aid of a clicking Huma Gear.

With the contest nearing its end, Aruto must redirect public sentiment back to the favor of Huma Gears. Meanwhile, Fuwa discovers the truth about the entity residing within the chip embedded in his mind.

Gai has assumed leadership of Hiden Intelligence and announced the decommissioning of all Huma Gear.

Aruto's first assignment at the company was a familiar one: to revive the Huma Gear, specifically the G-Pen.

The arrival of Huma Gear, a fashion model brought back by Aruto, throws Naki into a stark examination of his own existence: is he merely an instrument, or does a dream reside within him?

At Gai's command, Yaiba was tasked with eliminating Fuwa, who, unbeknownst to his superior, had acquired a discarded Huma Gear through illicit means.

Together, Yaiba and Jin endeavor to liberate Naki from Fuwa’s grasp. Meanwhile, Aruto's excursion to a greenhouse is unexpectedly disrupted by the arrival of Horobi.

Horobi safeguards Jin through sheer force of his own resolve; Naki reveals to Fuwa the truth of his former life.

With a swiftness born of necessity, the Ark seized control of Horobi’s form, dispatching Yaiba to the hospital. Meanwhile, Fuwa wrestled with a disquieting truth: the knowledge that his family was not, after all, dead.

At Ark's behest, Naki journeys to see Gai, while the company's vice president at Hiden plots a course to reclaim control.

When Gai barricaded himself within the laboratory, Aruto intervened, a touch of doubt clouding his thoughts about Gai's devotion to Hiden Intelligence.
