It has recently emerged that Manga Ent. are co-funding a new 13 episode anime series called Tokko. Adapted from an original manga written by GTO author Tohru Fujisawa, Tokko is a violent mystergy series currently airing on Japanese TV.
Given that Manga Ent. release everything they have a hand in worldwide (Dead Leaves, KARAS), it would be fair to assume that a UK release of Tokko is on the way.
