Jou, a worker-class asobot, embodies a ninja-inspired design with a face-concealing mask. His existence hinges on constant hydration, as prolonged dehydration proves lethal. In water-based environments, his combat prowess peaks, rendering him unbeatable in aquatic engagements.

Originally armed with the Feather Sword, his core systems undergo a metamorphosis upon securing six mission-critical keys. This evolution rebrands his weapon as the Feather Blade and triggers a physical redesign, while the keys activate latent functions tied to his core purpose.

As one of three asobots tasked with securing 49 keys to avert planetary collapse, he demonstrates unwavering allegiance to the unit. This loyalty culminates in his choice to chronologically reset with the group post-mission, prioritizing unity over personal ambition.

No supplementary media appearances are documented beyond his central narrative involvement.
