Children have been going missing following the schedule of the Noah's Ark circus. The Black Order finds these events suspicious and sends four of their available- er, best exorcists to look into these events. While infiltrating the circus Allen and co. run across a certain noble and his butler also on the case of the missing children. Rated T for possible (probable) obscenities.

Alternative Title: The Tale of Allen Walker the Grim Reaper. And the terribly, no good, very bad humans hunting him along the way.

Innocences have their own wants, personalities, souls - Allen doesn't understand what's so strange about this. But then, he's always been able to see them. (Series of oneshots through the manga. Mostly canon-compliant. May eventually turn AU.)

When Ciel calls out into the darkness, it isn't a demon who heeds his calling. Quite the opposite, really. Immortal!Allen Noah!Allen NO PAIRINGS, as far as I'm concerned.
