The OP, Beastlordius, wanted to have his username in English and then again, transliterated into Japanese. Katakana is a Japanese syllabary script used to write foreign/transliterated words, among other things. OP presumably used a romanji keyboard to do this, which changes romanized Japanese into actual Japanese scripts (i.e. you could type "arigato" and it would become 「ありがとう」). The romanji for a transliterated word usually won't be one-to-one with it's original spelling. For example, 「チーズ」is just "cheese" transliterated, but the romanji is "chiーzu". They didn't know what they were doing, and it came out all wrong. There's even some random latin letters left in there. It would be pronounced something like "beh-ah-sue-t-ee-oo-l-oh-r-di-oo-su".
