Chichi no Jikan

Chichi no Jikan follows Shinogi Kyūichi, a male biology student who lives in an apartment near a helpful female neighbor/friend, Takarai Ayaka. One day, he is visited by aliens, who demand that he raise their baby for a year… or else the world is history. The baby is apparently human, and is raised the way humans are: through breast-feeding. Kyūichi's sex is not a problem for the aliens: they give him a simple device that switches his body to a woman's with the mere touch of a button. Conveniently, Kyūichi's female form is very well-endowed. Although she's understandably confused and uncomfortable by the whole situation, Ayaka helps Kyūichi out as he navigates the unfamiliar experience of raising a child, and breast-feeding it in particular. That means going to a store to buy a breast pump, visiting a maternity hospital to get a massage to release Kyūichi's stored-up milk, and giving the baby a bath together. Kyūichi, as a biology student, is fascinated by the whole thing from an academic perspective.

Color Engineering

Gekigaka Yuichi Yokoyama (born 1967) draws wordless narratives of scenarios that verge on visual abstraction. Stripped of any detail that might orient them in the past, present or future, they record the self-determined activities of machines and architectural structures in a pre- or post-human universe. With his fourth volume for PictureBox, designed and edited by the artist himself, Yokoyama broaches significant new terrain: color! Color Engineeringreproduces both older and unseen imagery from the 2000s with dozens of color drawings and paintings that were executed in 2010 during a six-week open studio event held in Tokyo, at which the public was able to view Yokoyama at work. A selection of these canvases is reproduced here as gatefold pages, and is integrated among comic-strip sequences executed in a variety of techniques: photography, loose marker drawings, hyper-real portraiture and much more. These sequences continue his investigations into the world of machines, architecture and post-human fashion, and are the first Yokoyama narratives to provide insight into the artist's personal world, in details of his rural habitat.
