Genshiken author 木尾士目 / Shimoku Kio’s new manga “ぢごぷり” (misleadingly romanised as “Digopuri” – it is actually pronounced “Jigopuri”, an abbreviation of “Jigoku (Hell) Princess”) has begun serialisation in Afternoon. A departure from his previous themes, though still something of an everyday, slice of life story, it focuses on the tribulations of child rearing, with the antagonist of the title being the demanding baby illustrated above.
The painstakingly ugly rendition of the infant probably gives you the hint – this is a more realistic portrayal of the subject than usual, and apparently breasts and nappies do make plenty of appearances (see below), though not in a particularly titillating manner.
Personally, I would reserve judgement until it has a full compilation released. AkibaOS has more details and shots.
