Gachiakuta

Synopsis

Setting

Gachiakuta is set in a dystopian world, in which a floating country-sized structure known as the Sphere (天界, Tenkai) exists. The Sphere runs on a social caste that divides the rich and wealthy upper class from the poor "tribesfolk" living around the outer perimeter by way of a heavily guarded wall. The tribesfolk are descended from criminals and shunned by the upper class. Both sides of the caste wantonly discard anything they consider to be trash into the "Pit", a never-ending expanse below the Sphere, which is littered with waste and considered inhospitable to life by the Spherites (天界人, Tenkai Jin), the inhabitants of the Sphere. Anyone accused and convicted of a crime is also thrown into the Pit as a form of capital punishment. The Sphere and the Pit are separated by a mysterious border.

Unknown to the Spherites, the Pit is actually inhabited by a wide population who refer to the Pit as the "Ground" (下界, Gekai) and have formed a network of civilizations. The Ground is a mostly toxic environment infested with the Spherites' waste due to the constant downpour of trash from the Sphere, and its heavily polluted areas are populated by transformed creatures known as Trash Beasts (斑獣, Han-jū), born from Anima (思念, Shinen) energy accumulated from thoughts and emotion. Regular weapons are ineffective on Trash Beasts due to their regenerative properties. They can only be defeated by superpowered people known as "Givers" (人通者（ギバー）, Gibā), who have formed teams known collectively as the Cleaners (掃除屋, Sōjiya) and wield weapons known as Vital Instruments (人器, Jinki) in battle, as only these can affect Trash Beasts.

Vital Instruments are everyday objects that have been infused with Anima generated from the Giver's body. They manifest from the Giver's own love for the object, allowing their Anima to awaken and transform the object into a specialized weapon. The longer a Giver has cared for that object, the more powerful it becomes as a Vital Instrument, as it also serves as a conduit for a Giver's own experience and ideology as a person. Among the many Vital Instruments are those in the Watchman Series (番人シリーズ, Bannin Shirīzu), which are supposedly especially powerful and usually require the wielder to have lost something in their life to use them without succumbing to insanity. This series is believed to be connected to the Watchman (番人, Bannin), a gigantic, incomprehensible being guarding the border between the Sphere and the Ground.

Plot

Rudo Surebrec lives with his foster father, Regto, in the slums of the Sphere. Regto took Rudo in after his biological father, a notorious serial killer, was thrown into the Pit. Rudo detests the upper class's wastefulness, as they frequently discard anything they deem to be trash, even new or unused items. To this end, he spends his days rummaging through dump sites to salvage and often sell such items.

One day, after looking over the execution site, Rudo encounters a mysterious passerby before returning home to find Regto murdered. Apprehended at the scene, Rudo is immediately convicted of killing Regto, due to his status as a tribesman. Unable to escape his fate, Rudo swears revenge upon his accusers as he is dumped into the Pit.

Upon awakening, Rudo finds himself disoriented in an endless landscape of trash. He is attacked by large creatures made of trash but is rescued by a man named Enjin, who explains to Rudo that he has fallen to the surface from the Sphere. After testing him and awakening his power as a Giver, Enjin invites Rudo to join the Cleaners, teams of Givers who use their Vital Instruments to battle the trash beasts. Rudo reluctantly accepts Enjin's offer, so long as it helps accomplish his ultimate goal.

Production

Series creator Kei Urana credits experiences in her childhood as the main inspiration for Gachiakuta. The story's premise, where actions and feelings are imbued into personal belongings as "Anima", developed after Urana broke a belonging of her own as a child: "I had a pen that I really loved, and I broke it in two. Along with the sense of loss, I had a feeling like the pen was pleading with me". Urana's experience is reflected in Gachiakuta as the story focuses on many characters who explore strong, personal connections to Anima-imbued objects called "Vital Instruments", and in Rudo's case, even trash thrown away by others. The idea for these Vital Instruments also originated in Urana's youth from observing the hangers that came with her grandmother's dry cleaning, a testament to Gachiakuta's themes about seeing value and potential in seemingly mundane and discarded things.

Gachiakuta's art style is due to illustrations by Urana, complemented by graffiti designs from Ando Hideyoshi. Graffiti and street art provide not only avenues for expression, distinction, and safety for the story's characters, but also narrative significance for readers due to its use in storytelling. As for character design, Urana states that her process involved unexpected changes for Gachiakuta's characters: "I create them to be decent people, but then I actually draw them and for some reason, they turn out to be freaky weirdos. I've given up, realizing that this is who they truly are".
