Otoha (0T0H4M3G4M1)

Otoha (Real Name 0T0H4M3G4M1) is the real personality of Haruka Shirogane. She's one of the main antagonists for Tenshi Arc, and the upcoming Akuma Arc. She lives in Haruka's mind, and can be seen only by her, however, she cannot take full control of the latter's body and is considered a second personality of hers.

As an idol, Otoha dreamt of being a Prism Star before becoming an "illusion". She still hasn't given up, and it's hinted she'll debut after her arc is done.

Her codename is the same as Haruka, and it comes from the fact that Kou Shirogane, her father, created her (and Haruka) to become a goddess who he'd end up using as a toy to rewrite the world as he  likes it. However, this didn't happen as the experiment failed, and now she's nothing but an insane powerless girl with crushed dreams of becoming an idol...

Appearance
Otoha has long, straight dull lavender hair with yellow streaks that reaches below her shoulders. Part of her hair is tied up by a dark blue ribbon, similar to Haruka's. Her eyes are lifeless, of an ice blue color, and when she's speaking or doing anything at all, Haruka's eyes change color as well.

Personality
Otoha was a nice, kind-hearted girl who loved to help others when needed. Not much is known about her past self, but it's said she was the opposite of what she is now.

The present Otoha is a gloomy, powerless girl who suffered a lot during her life. She might seem evil and manipulative, but she still cares about Haruka's friends and acts selfish just to save them from Tenshi. It's hard to make her give up, as she mostly represents Haruka's tough self. The very rare times when she shows any positive emotion, however, she reveals a childish and hyper self.

Trivia

 * She's actually stupid.
 * She usually takes all the blame on purpose, so that everyone can be happy.
 * She might seem like the "evil" side of Haruka, but deep inside, she's twice as good as her.
