We have three tags that I can find for this guy (bow_ditama, ditama and ditamabow). In the west he's usally called "Bow Ditama" and that appears to be how he writes his own name romanised (see http://images-jp.amazon.com/images/P/4847035526.09.LZZZZZZZ.jpg ) but I wanted to check how you wanted it done here before I tried retagginh or requesting aliases. The kanji is ぢたま某 however he usually writes the 某 in a circle for some reason (as noted on http://ja.wikipedia.org/wiki/%E3%81%A2%E3%81%9F%E3%81%BE%E6%9F%90 )
If this is his real name then precedence suggests using "jitama_bou" (c/v itou_noiji etc.)
