i dont know ... they all are nice names.
kururu is katakana for "krile", so krile must be the official name. cara is nice too.
( k=ku, ri=ru, and le=ru)the japanese dont have an "l" sound, so a short "ru" is often a substitute
just sos ya know, katakana are japanese letters that are used for foreign words and sounds. (yes, i take japanese
) they were kinda hard to memorize for me...
