Story Overview
In the 2070s, the New Tesla Foundation has covered Earth with coil tower technology that draws limitless energy from the fourth dimension — Dimension W. Coils power everything. Illegal coils are unregistered and dangerous; their interactions with Dimension W's unstable zones can cause reality anomalies.
Kyoma Mabuchi is a coil hunter — he retrieves illegal coils for the Foundation. His distinction: he refuses to use coil-powered technology and drives a gasoline-powered car. His reasons for this are personal and connected to a past that the series reveals gradually.
Mira Yurizaki is an advanced android — the final creation of the Foundation's lead scientist, who has died under mysterious circumstances. She has a numbered coil at her core that may be connected to the most dangerous illegal coil case Kyoma has encountered.
Characters
Kyoma Mabuchi — His principled rejection of the technology everyone else uses is both the series' comedy element and its most consistent character statement. What happened to produce this refusal is the backstory that the series earns the right to reveal.
Mira Yurizaki — Her development from a robot following inherited directives to an individual making choices is the series' most complete character arc. Her status as an android — genuinely conscious or not, and what the answer implies for how she's treated — is the series' philosophical center.
Art Style
Iwahara's art is exceptional — the coil technology designs, the Dimension W visual effects, and the action sequences are all executed with technical command. The character designs are distinctive and the near-future world is detailed in ways that make it feel inhabited.
Cultural Context
Dimension W engages with Japanese science fiction's long interest in android consciousness — the question of whether Mira experiences the world the way humans do and what obligations that creates is treated with seriousness within the action framework.
What I Love About It
Kyoma's gasoline car. The choice to give the protagonist a technology that the entire world has abandoned — and the specific reason for this — is a worldbuilding decision that does more characterization than pages of backstory exposition.
What English-Speaking Fans Say
Western readers describe Dimension W as the sci-fi action series that surprised them most with its emotional depth — the Kyoma/Mira partnership develops into something more affecting than the action premise suggests. The art is consistently praised as among the best in the genre.
Memorable Scene ⚠️ Spoiler Warning
The revelation of Kyoma's past and its connection to the original coil development — how personal loss connects to the technology he refuses to use — is the series' emotional climax and makes the gasoline car's significance fully clear.
