Skeith may owe its name to the Skeith Stone, an artifact found in Kilrenny, Scottland. Inscribed in the stone is a circular cross, outlined by eight leaf or eye shapes and a squiggle that identifies it as a Chi Rho Cross (the one that looks like a P and a X combined, those being the Greek letters used to spell Christ).
"Skeith" means "Shadow" in Old Scottish. The spelling of Skeith seems to have changed through the ages, being found as Skeith, Skuth, Skeycht and Skyith.
Character Designer Yoshiyuki Sadamoto based the proportions of Kite on the character Naruto. Interestingly CyberConnect 2 would eventually go on to develop the Naruto Ultimate Ninja game series.
In the original Japanese version of Infection, Skeith's wand, which appears in the English version as a large, red staff with a "Q" shape at the tip, is actually represented by a Celtic cross. This was censored for the American release in favor of the Q-shaped version from .hack//SIGN, though it is still seen as the cross in some American media.
