Well, it is her name, and it isn't. Lol! Let me explain, after hearing it in FFX, I really liked the name Rikku, so I tried to find out what it meant in Japanese, but it doesn't mean anything apprently. It's just a name. But, I name up the name Ririkku instead, and searched for that, and foudn out it means "Lyric". So I used to have that name, but then changed it to Rikku, coz I like that better. And the Otaku I kinda borrowed from my fiance because his online name is Phoenix Otaku. Hehehe!! So yeah, it all started because Rikku on FFX. Her and Yuna are my fave characters from that game. ^_^ I love FF games!!
