Back Arrow (Japanese: バック・アロウ, Hepburn: Bakku Arō) is an original Japanese anime series produced by Studio VOLN, directed by Gorō Taniguchi and written by Kazuki Nakashima. The series aired from January to June 2021.

Plot

[edit]

The series takes place in the land of Lingalind (リンガリンド, Ringarindo), a continent completely surrounded by a massive wall. The people of Lingalind revere the wall as a god, believing that all of existence is contained within and that the wall protects and provides for its inhabitants. While the land consists of several territories, it is mostly dominated by two powerful nations: The Republic of Lutoh (リュート卿和国, Ryutō Kyōwakoku), which values intelligence and diplomacy, and The Empire of Rekka (レッカ凱帝国, Rekka Kai Teikoku), which values honor and strength. These two nations are in constant conflict with each other over obtaining land and Rakuho (ラクホウ) capsules, which are sent from an unknown location once per month and land in predetermined regions of Lingalind, containing provisions and weapons that the people of Lingalind consider gifts from the wall. Some of these capsules contain devices known as Bind Warpers, metallic armbands that allow one to summon and control a giant mechanical armor known as a Briheight (ブライハイト, Buraihaito). A Briheight's appearance and abilities are tied to one's Conviction (信念, Shin'en), the thing they believe in above all else. Conviction is also recognized as an energy that flows throughout the world, powering various forms of advanced technology found within Lingalind and granting some people special abilities outside of operating a Briheight. Being defeated in battle while controlling a Briheight causes the user to disappear.

One day after a Rakuho is recovered by Rekka forces, a previously unheard-of second Rakuho lands in Edger Village on the outskirts of Lingalind's Iki region. Inside is an amnesiac young man whose only memory is that he is from "beyond the wall." Taking the name "Back Arrow," he seeks to journey back over the wall to restore his memory, entangling himself in the conflict between the two nations.

General Kai Rhodan of Rekka claims a "Rakuho" which lands near the Lutoh Republic border containing a cache full of Bind Warpers. A Lutoh unit of Briheights soon arrive, but he defeats them by becoming a Briheight himself. A second Rakuho is then seen streaking across the sky, heading for uninhabited Iki Territory and Rekka High Diviner, Shu Bi, goes to investigate with warrior Ren Sin providing support. The second capsule lands in the remote Edgar Village. Villager Bit Namital suspects there's food inside, so the villagers start boiling the capsule while Shu Bi watches from afar. The capsule opens and a naked youth jumps out, recalling only that he came from "beyond the Wall", much to everyone's disbelief. Suddenly, a bandit attacks the village and uses his Briheight to obtain the Rakuho treasure. The sheriff, Atlee Ariel, attempts to defend the village and stop the destruction with her own Briheight, but she is trapped by the bandit. The naked youth grabs a Bind Warper from his capsule and transforms into a unique Briheight, Muga, rescuing Atlee and destroying both the bandit's Briheight and Bind Warper, although unusually the bandit survives. Bit has repeatedly called the naked youth an idiot, a "bakayaro!", which the young man mistakenly hears as "Back Arrow", and takes it as his name.

Back Arrow invokes his Briheight Muga and defeats Duster's Briheight and breaks Duster's Bind Warper, but again this does not cause the death of the wearer.

Shu fits a giant Bind Warper to Arrow's Muga form while claiming that he rewrote Arrow's data, enabling Arrow to return to his human form. He then reveals that his human body is asleep in the Granedger and that his Briheight looks exactly like his human form. When Shu awakes, he explains that it was his Briheight form which disappeared when Arrow touched him. He says that he deduced that Arrow's power turns living beings into conviction particles which are absorbed by God to nourish the deity and it was part of Shu's risky plan to return Arrow to his human form. Meanwhile the Rekka forces capture arrow for killing Zetzu, but Shu offers information about God in exchange for his release. Shu starts by explaining that there are many "worlds" like Lingalind, like a snowflake with God's realm at the center and a "Lind" nodule surrounded by a wall at the end of each extension. Shu estimates that they can only reach God through Epitaph Mountain to negotiate with the deity. However, Kai challenges Arrow to a duel, and uses Zetsu's weapon, but Arrow refuses to fight and dodges Kai's blows. Arrow eventually realizes that it was the will to survive in the people he met in Lingalind which changed him from being a destroyer into a savior.

Arrow and the Edger leaders head off to confront God over the planned destruction of Lingalind while Shu and Kai reconcile and join forces. They leave in Granrekka for Epitaph Mountain and the wall vanishes as they approach but they are confronted by Rudolf. He releases the Rondo of Ruin, a gigantic Rakuho device that begins to destroy Lingalind while he creates a gigantic multi-pronged spear which immobilizes Granrekka and neutralizes their Briheights. Arrow summons his energy and conviction to save the population and his Saberblow converts the spear's prongs back into pillars. Granrekka then fires an Astonishment Maser blast at Rudolf and attempts to stop the rotating Rondo of Ruin, but without success. Rudolf unleashes his Arbitrator powers, but Fine absorbs Granrekka's damage with Lovesolute while Kai combines Arrow's Muga Sword, Ren's conviction and Zetsu's Martial Arrow to destroy the Rondo of Ruin. Rudolf manifests it again, but Shu encourages them the blast through it to the other side. They break in to God's realm and confront a man with a similar appearance to Arrow and his Briheight looks like a dark version of Arrow's Muga.

The united Lingalind forces battle Rudiof's Diobenedica and Dissonanza's Phantasmone whose connection to God's power is suddenly broken. Relying on their own powers, Rudolf and Dissonanza continue to fight on. Meanwhile, Atlee challenges the man to explain why Lingalind and its population should be destroyed. He describes how a fleet of space ships carrying God's ancestors was struck by an epidemic and only a young newborn boy would survive. The ancestors created the "Lind" system to protect and nurture the child via a supply of conviction and left him as his guardian. However the survival instinct of the Lingaland people exceeded the system limits and like a malignant growth, it was destined for destruction in case it spread to other Linds. The guardian commences the destruction of Arrow and the others, while Rudolf's attack causes the Dark Fine to appear. Under Bit's urging, the Lingalind forces, including those who died and were converted to data, launch an all-out attack, destroying Rudolf and Dissonanza. Arrow offers to personally return the child to its home and his plea is heard. The Lingalind leaders reach the gigantic child which has been in stasis for 2,000 years. One month later, Shu has revised the conviction cycle, and developed an interstellar warp system. Shu, Bit, Elsha, Atlee and Arrow head off in their space ship to find God's home world, the third planet of the Solar System, called Earth.

Reception

Critical response

Back Arrow received mixed reviews from critics, who praised director Goro Taniguchi's handling of the series' elements and action sequences while critiquing its pacing and character development. reviewers highlighted the innovative concept of Briheights as manifestations of personal conviction, noting the smooth integration of CG designs and bombastic fight choreography that elevated the action to "good-to-great" levels, particularly in episodes featuring dynamic camera work and non-lethal combat resolutions. Similarly, Otaku USA Magazine commended Taniguchi's return to original storytelling, drawing parallels to his earlier works like s-CRY-ed and Gun x Sword, and appreciated the sharp character and robot designs that supported engaging twists in a divided, wall-enclosed world. Critics pointed to rushed pacing as a recurring issue, with the plot advancing too quickly to allow for deeper exploration of its setup, resulting in episodes that lacked breathing room amid escalating conflicts. also noted that while the core cast had charming rapport and fun dynamics, supporting characters often felt underdeveloped or overlooked, especially in the finale where rushed growth left figures like Atlee and Elsha underexplored. Despite these flaws, the series was seen as a solid modern entry with heart and visual flair.

Discussions often highlighted these action sequences as a highlight, evoking classic super robot adventures while incorporating fresh twists on themes of conviction and destruction. The finale, however, proved divisive, praised for its thematic resolution—culminating in Arrow's departure from Lingalind toward Earth—and visual spectacle, but critiqued by some for rushed character developments in arcs like those of Atlee and Elsha. As of November 2025, no sequel announcements have emerged, leaving the story's impact tied to its cult following within mecha communities.

Episode notes

The first arc, spanning episodes 1 through 6, establishes the setting in Edger Village and introduces key characters and the concept of belief-manifested , with episode 1 featuring a specially crafted opening sequence that highlights protagonists Kai, Shu Bi, and Ren to quickly orient viewers and avoid a slower introduction focused solely on village life. This early setup was scripted to emphasize the world's mechanics, such as Atlee's "get by for now" and Kai's "peerless" Briheight designs, drawing from initial collaborations between director and writer on materializing beliefs into robots. A significant production shift occurred during animation development, initially planned as fully hand-drawn but adapted to incorporate 3DCG for dynamic robot action sequences due to constraints in hand-drawn expertise; this hybrid approach was refined by guest mecha designer and action supervisor Rihiro Yamane to blend 3DCG with traditional animation seamlessly across arcs. Mid-season adjustments in episodes 13-18, covering the escalating war arcs between the Empire of Rekka and the Republic of Lutoh, involved pacing refinements to balance philosophical themes with action, though the core script—completed as early as 2017—remained largely unchanged owing to the story's timeless, self-contained world. Notable trivia includes Easter eggs referencing Taniguchi's past works, such as Shu Bi's character design echoing Lloyd Asplund from , a nod suggested by Nakashima during early scripting, and broader inspirations from Taniguchi's involvement in for mecha belief systems. Additionally, episode 8 introduces the Demain Choir, a choral element composed by guest musician Hironori Tanaka, intended as a potentially polarizing auditory motif to underscore the series' thematic depth in later arcs.
