Raised together within the Oboro Clan, Hotsuma and Moritsune were seldom apart during their youth. Being the younger of the two, Hotsuma looked up to Moritsune, and considered his older brother a superior warrior.
It was After they discovered Akujiki; the cursed katana of their ancestors that they realized their fates were sealed. The Oboro clan commandments deem that the next clan heir was to be decided via a savage ritual between the clan leader's eldest sons. Hotsuma and Moritsune were aware of their destinies and trained for ten years under their foster father and master Kobushi. The duel occurred on a full moon in the summer time in a cherry blossom grove.
Four years after that night, not a day has passed that Hotsuma hasn't thought of Moritsune, but when a Golden Palace rises from Tokyo's Water Front City after the city is struck with a catastrophic earthquake, Hotsuma has other things on his mind; who has murdered his clan, and why has Tokyo become a demon infested hell on earth?
