Well it is from Ikkitousen. The source even links to an Ikkitousen Page. Seems there'll be some new DVD coming end of Dec. Most of the characters haven't been seen yet besides the manga. The one in front is Chohi. The one with the long violet hair is Kanu. The one with glasses is Ryubi. The one with blue hair should be Shokatsuryu but i am not sure and i have no idea about the one with white hair.
