Seinen manga magazine Gekkan Young King brought in a couple of hentai artists to kick off somewhat more mainstream series in its July issue, on sale May 20th.
Kentarou (Samurai Guild - Kepuuroku) goes for a supernatural, racy story in Hyakuki Yakou.
Takeshi Ohmi works a more straight forward battle of the sexes in Kiss My Ass. And if you thought that the title was audacious, wait until you see the logo.
Though on the face of it, it seems unlikely that this pair of manga would be licensed, a few series from Gekkan Young King have been released in English. Tokyopop released IkkiTousen author Yuji Shiozaki's wrestling series Battle Club while JManga carried Tsumanuda Fight Town.
