Mariko

Mariko (まり子) is the cousin of Kaoru Nishimi.

Etymology

 * The name Mariko is written in kanji/hiragana (まり子), which has no special meaning except the kanji "子" means "child". However, when part of the name Mari is written in kanji (真理 or 真里), it could possibly mean:
 * 真理 - "real, genuine" (真) (ma) and "reason, logic" (理) (ri).
 * 真里 - "real, genuine" (真) (ma) and "village" (里) (ri).
