From Kotonoha:

"Garden" is a collection of Furuya Usamaru's “indie” shorts that were published in Comic Cue, Manga Erotics and GARO respectively. The title is obviously a reference to Hieronymus Bosch’s famous triptych The Garden of Earthly Delights, with the first story being a homage to said painting. The other stories range from absurd comedies to fantasy to horror. It’s a very eclectic mixture, but make no mistake: artistically, Garden might just be Furuya’s most accomplished work after The Music of Marie.
