One-shot story published as a special prologue chapter to the 4th Bleach movie, Jigoku-hen.

Witches, dragons, and reverse London.

From Viz:
Somewhere in the desert lies the world's greatest treasure: the 12 Rings of the Dead, the only source of the mysterious substance Zombie Powder, which can raise the dead and grant eternal life. Into this world stalks Gamma Akutabi, a man with a metal arm and a six-foot chainsaw, cybernetically enhanced master of the legendary martial art.
But it takes more than one man to find the ultimate prize. You need a team: super-gunman C.T. Smith, knife-slinging teenager Elwood, and brilliant (and impossibly big-breasted) journalist Wolfgangina. Against an army of crooks and killers, against runaway trains and super-powered madmen, they'll need all their skills... but the most dangerous thing in the west might be the Rings themselves.

Includes 3 one-shots:
- Ultra Unholy Hearted Machine Vol 2
- Rune Master Urara Vol 3
- Bad Shield United Vol 4

Ichigo Kurosaki has always been able to see ghosts, but this ability doesn't change his life nearly as much as his close encounter with Rukia Kuchiki, a Soul Reaper and member of the mysterious Soul Society.
While fighting a Hollow, an evil spirit that preys on humans who display psychic energy, Rukia attempts to lend Ichigo some of her powers so that he can save his family, but much to her surprise, Ichigo absorbs every last drop of her energy.
Now a full-fledged Soul Reaper himself, Ichigo quickly learns that the world he inhabits is one full of dangerous spirits, and along with Rukia, who is slowly regaining her powers, it's Ichigo's job to both protect the innocent from Hollows and to help the spirits themselves find peace.
