Wouldn't it be best to just affix those one-page omakes to the end of the relevant chapters instead of putting them separately? It needlessly bloats the chapter list, and sets people up for some disappointment.
@Askorti: Not very technically practical, since releasing itself coming in such way. One week chapter, one week omake. @Aichan: Don't worry, both author and editor of this manga are on "blood-related side". Not mention, that there already too much implications against such twist.
