The article also talks about the story itself. As made apparent by the media released so far, the setting seems to be a mishmash of other general settings. The main group are a team of "samurai" that originate from a middle-ages style castle city by the name of Mikado of the East. The samurai in Mikado are armed with electronic gauntlets with an installed demon summoning program. Their quest takes them to Tokyo, where they must halt the spreading of demon influence after the area has already fallen into darkness.
We'll have more info as it becomes available.
