There are several female characters in the hit series "Death Note". The most prevalent character was Misa Amane "Misa Misa". Misa's character was shy, physically weak, submissive, and written to be emotionally and physically dominated by the main character, Yagami Light. There was not a single episode in which Misa was not "willingly" at the mercy of Light. Misa was frequently animated in sexually submissive poses that were intended to be readily enjoyed as eye-candy for every male character of Death Note that was sexually interested in her. At no point in the series did Misa refuse any male that sexually harassed her. In fact, she was portrayed to not only be sexually submissive, but was also substantially less intelligent than her male counterparts.
The second most prevalent female character was the Shinigami Rem. Rem's whole purpose in the show was to protect Misa. The relationship between Rem and Misa was that of solidarity. Their solidarity lasted until the middle of the storyline. Like Misa's role, Rem was more than willing to be a martyr. Rem died to protect Misa because she was tricked by Light. Rem's good intentions to protect Misa were ill founded, because Misa committed suicide after the death of Light.
The rest of the significant female characters had limited roles in which they either died or almost died at the hands of Yagami Light or another death note owner.
How could this anime be feminist friendly and still maintain it’s pop appeal?
1. The writers could have written Misa's role as woman who was not constantly being physically objectified, intellectually incompetent, and emotionally submissive. Instead of writing her as the "weaker" character, Misa could have been a heroine.
