diff.text: His name, just like the girls, carries a pun. His surname ''Chiba'' means ''Local'' and contains the kanji &#22320; - ''chi'' which also appears in the word ''chikyuu'' meaning ''Earth'' and &#22580; - ''ba'' meaning ''place'' or ''location''. His given name ''Mamoru'' &#34907, means ''to protect''. So the pun in his name is '''loosely''' ''Earth Protector'' or ''Local Protector''.
diff.text: He is voiced by [[Tohru Furuya]] in the original anime and in the English dub by  [[Rino Romano]], [[Toby Proctor]] and [[Vince Corazza]]. In the 2004 live action series ([[Pretty Guardian Sailormoon]]) he is played by [[Shibue Jyoji]].
