Rumi Hidaka is Mima's manager and the main deuteragonist in Perfect Blue.


Perfect BlueEdit

Rumi was a pop idol herself before changing careers, much like Mima. She becomes her agent during her time as a pop idol, but when Mima wanted to change careers, Rumi helps her on the set of 'Double Bind'. However, when the producers wanted to film a rape scene with Mima, Rumi becomes disgusted and angrily replies that Mima shouldn't do such an act. Mima accepts the part, but Rumi informs her that it will ruin her reputation.

In secret, Rumi uses her 'real' Mima personality to murder the people who tarnished Mima's reputation. Or at least, the people she percieved as being responsible, including the screenwriter of 'Double Bind', the actors involved in the rape scene, and even Mr. Tadokoro, Mima's office manager who thought her transition into acting would be positive, rather than negative.

Rumi becomes tearfully emotional when she witnesses Mima being 'raped' on the set and leaves. Days later, Rumi continues to support Mima, even when she shows signs of distress.

It's not until the ending that we see Rumi was behind it all, the website, the murders, and she even contacted Me-Mania for the diary entrys, while under the 'real' Mima alias. Rumi is injured after chasing Mima in the city and awhile later, she is sent to a mental facility, where she continues to switch her personality with that of the 'real' Mima.


Rumi is likely to suffer from dissociative identity disorder, as she switches personalities from herself to 'real' Mima. Although she cares a lot about Mima, even when it comes to her reputation. It is possible that Rumi went through the same phase as Mima did when she changed careers but unlike Mima she could not cope with the stress giving her DID.
