Context: Romeo × Juliet (ロミオ×ジュリエット , Romio to Jurietto ) is an anime television series, loosely based on William Shakespeare's classical play, "Romeo and Juliet", along with numerous references and characters from other Shakespearean plays.  Though the anime borrows mostly from Shakespeare's story, the manga adaptation differs extensively from the original.  "Romeo × Juliet" was broadcast in Japan on Chubu-Nippon, broadcasting from April 4, 2007 to September 26, 2007.  In 2009, "Romeo × Juliet" was dubbed into English and released by Funimation Entertainment. The North Irish Horse is a yeomanry unit of the British Territorial Army raised in the northern counties of Ireland in the aftermath of the Second Boer War.  Raised and patronized by the nobility from its inception to the present day, it was one of the first non-regular units to be deployed to France and the Low Counties with the British Expeditionary Force in 1914 during World War I and fought with distinction both as mounted troops and later as a Cyclist Regiment, achieving 18 battle honours.  The regiment was reduced to a single man in the inter war years and re-raised for World War II, when it achieved its greatest distinctions in the North African and Italian campaigns.  Reduced again after the Cold War, the regiment's name still exists in B (North Irish Horse) Squadron, the Queen's Own Yeomanry and 69 (North Irish Horse) Signal Squadron (V), part of 32 Signal Regiment.

Vargo Statten Science Fiction Magazine (later Vargo Statten British Science Fiction Magazine, The British Science Fiction Magazine and The British Space Fiction Magazine) was a British science fiction magazine which published nineteen issues between 1954 and 1956.  It was initially published by Scion Press, with control passing to a successor company, Scion Distributors, after Scion went bankrupt in early 1954.  At the end of 1954, as part payment for a debt, Scion Distributors handed control of the magazine to Dragon Press, who continued it for another twelve issues.  E.C. Tubb and John Russell Fearn were regular contributors, and Kenneth Bulmer also published several stories in the magazine.  Barrington Bayley's first published story, "Combat's End", appeared in May 1954.  The editor was initially Alistair Paterson, but after seven issues Fearn took the helm: "Vargo Statten" was one of Fearn's aliases, and the magazine's title had been chosen because of his popularity.  Neither Paterson nor Fearn had enough of a budget to attract good quality submissions, and a printing strike in 1956 brought an end to the magazine's life.
