Emi

Emi (えみ) is a girl whom Light Yagami once dated.

Plot
After Light kissed Misa Amane for the first time, Light mentioned Emi and a girl named Shiho to Ryuk as girls he has dated before.

Etymology

 * The name Emi is written in hiragana (えみ), which has no special meaning. However, when written in kanji (恵美 or 絵美), it could possibly mean:
 * 恵美 - "favor, benefit" (恵) (e) and "beautiful" (美) (mi).
 * 絵美 - "picture, painting" (絵) (e) and "beautiful" (美) (mi).

Trivia

 * Misa mentions Emi in her love diary seen in Death Note 13: How to Read, in a section where she writes about how she defeated other girls Light dated in her pursuit for him. Emi and Shiho are categorized under "other sluts." Misa states that anyone who was never actually shown automatically loses.
