Akai Katana

Akai Katana Shin takes place in a fictional era resembling the years of industrial expansion in Japan, full of hope for reconstruction. Amidst record-breaking economic growth and technical innovation, the people of this era discover a new energy source, a mineral called Guiding Ore. A powerful natural resource, this Guiding Ore held other mysterious qualities. It could be tempered into a blade, a "Guiding Katana" that endowed certain soldiers who held special symbols with access to a unique psychic power.

 It was said that once this katana killed another human being, it would turn blood-red and endow its owner with an overwhelming power. It was this power that the Emperor Basho used to expand his reign, waging war on his country's neighbors with an elite battalion who wielded the so-called "blood swords". Now only a small squadron of rebels stands against his empire and its most fearsome generals. The struggle for justice begins here.
