Character Overview

Enjin Gachiakuta is one of the most experienced and powerful Cleaners in the underground world of The Pit. Introduced early in the anime, Enjin becomes a crucial figure in protagonist Rudo’s journey, guiding him through the brutal hierarchy and survival rules of the Cleaner society. As a senior Cleaner, Enjin not only excels in combat but also understands the ideological foundation of the world they live in.

Enjin represents the transitional bridge between the corrupted upper society and the resistance movement formed underground. His words are few, but his actions often define the direction of Cleaner missions and training. With years of survival, tactical expertise, and raw combat strength, Enjin plays a central role in shaping Gachiakuta’s storyline.

Backstory & Origin

Enjin’s exact backstory has not been fully revealed in the anime, but clues indicate that he once lived in the upper world before being condemned to The Pit. His survival and transformation into a top Cleaner suggest both a strong will and a tragic past. He speaks little of his life before becoming a Cleaner, but carries scars—both physical and emotional—that hint at betrayal and personal loss.

His deep understanding of the system’s injustice makes him one of the most politically conscious characters in Gachiakuta. Unlike younger Cleaners who simply fight for survival, Enjin fights for purpose and change. His leadership is built on wisdom and battle-tested experience.

Relationship with Rudo

Enjin and Rudo share a complicated yet powerful mentor-student dynamic. At first, Enjin is skeptical of Rudo’s presence and emotional impulses. However, after witnessing Rudo’s use of the 3R Gloves and his raw moral drive, Enjin begins to guide him. He becomes a quiet teacher—pushing Rudo in combat, challenging his ideas, and occasionally offering rare words of encouragement.

Enjin sees in Rudo the possibility of a true shift in the world’s balance, something even he no longer hoped for. This growing respect between them forms one of the emotional pillars of the anime. Their interactions often reflect the contrast between youthful rebellion and hardened realism.

Vital Instrument – Scrap Blade

Enjin wields a large mechanical weapon known as the Scrap Blade, one of the most durable and versatile Vital Instruments among the Cleaners. Forged from a fusion of broken machinery and energy-conductive scrap, the Scrap Blade is a symbol of destruction and restoration. Enjin can change its form during battle, extending its reach or transforming it into defensive armor.

The weapon syncs with Enjin’s intense mental discipline and is known to burn with a fiery aura when his emotions are high. Unlike Rudo’s adaptive gloves, Enjin’s blade is raw, brutal, and precise—reflecting his personality and battle philosophy.

Powers and Combat Style

Enjin’s combat style emphasizes power, control, and surgical efficiency. He rarely wastes movement, delivering devastating blows in short bursts. His strength comes not just from the Scrap Blade, but from years of experience reading opponents, terrain, and timing.

• Scrap Energy Manipulation: Channels kinetic force through metal debris for large-scale attacks.
• Counterweight Tactics: Uses his weapon’s shifting mass to trap, confuse, or disarm enemies.
• Strategic Combat Sense: Predicts enemy moves and adapts instantly to unpredictable situations.

Personality Traits

• Calculating and calm under pressure
• Blunt, rarely speaks unless necessary
• Deeply loyal to fellow Cleaners
• Believes in structure but supports rebellion when justified
• Emotionally reserved but not emotionally absent

Voice Actor

While the Japanese voice actor for Enjin is yet to be confirmed, fans expect a veteran seiyuu known for powerful and reserved roles. His voice must capture both authority and depth—making casting critical to the character’s impact.

For the English dub, no announcements have been made, but studios are expected to cast a mature male voice similar to past characters like Levi from Attack on Titan or Aizawa from My Hero Academia.

Importance in the Story

Enjin stands as the foundation on which Gachiakuta’s deeper message is built. His mentorship of Rudo and leadership within the Cleaner faction make him vital to both character arcs and world-building. He challenges not just the external conflict but the internal moral questions of survival, justice, and sacrifice.

As Gachiakuta grows in complexity, Enjin is expected to play a larger role in uncovering the origins of The Pit and the corruption above. His presence elevates the anime’s emotional stakes and narrative depth.
