The megacorp that sealed Japan's cities under domes and abandoned the railways — and why Emi Araki and the rebel crew are taking the tracks back.
Miraidō (未来堂) Corporation is the central antagonist organisation of Denshattack! — a powerful megacorp that responded to climate collapse by sealing Japan's elite cities under massive air-purifying domes. The dome cities maintain pristine air quality for those who can afford to live inside them.
Everyone else — including Emi Araki and the rebel crew — lives on the outside, on the abandoned railways connecting dome cities that Miraidō no longer maintains. These discarded tracks are where Denshattack! takes place.
Major Japanese cities — Osaka, Tokyo/Kanto, and others — are sealed under Miraidō's air-purifying domes. Inside: clean air, corporate control, prosperity. Outside: the real Japan — open sky, abandoned infrastructure, and the people Miraidō left behind.
The VACTRAIN is Miraidō's ultimate project — the fastest train in existence, running on vacuum tubes between dome cities. Emi's goal to "race the fastest train in existence" is a direct confrontation with Miraidō's flagship achievement.
When Miraidō sealed the cities, the connecting railways were left to decay. The rebel crew reclaimed these tracks — turning Miraidō's abandoned infrastructure into the playground where Denshattack! happens.
Each region has a gang controlling the local tracks — nominally independent but all ultimately operating under Miraidō's shadow. Defeating each gang leader and recruiting them to Emi's cause dismantles Miraidō's regional control one chapter at a time.
The domes exist because of environmental collapse — Miraidō positioned itself as the solution to a climate disaster, using that crisis to justify control over who gets clean air. The game's political subtext is direct: corporate solutions to climate change that benefit only the wealthy.
Every dare completed and every gold medal earned is Emi reclaiming public infrastructure Miraidō abandoned. The trick system isn't just gameplay — it's the rebel crew asserting that these tracks belong to everyone, not a corporation.
The campaign follows Emi moving from region to region — each sealed under a Miraidō dome. As she defeats regional gang leaders and turns them into allies, she builds toward a direct confrontation with Miraidō itself in the final chapter ("The Full Force of Denshattack").
The final boss is expected to be Miraidō-related — the "Denshattacker Army" mentioned in the Steam description as a boss type suggests a final confrontation with Miraidō's enforcement apparatus or the VACTRAIN itself.
