Unicorn thinks very highly of Faruru and is somewhat overprotective. She seemed somewhat like Usagi, except that she acted more arrogant and cold. However, she did it with reason - to keep Faruru from getting too close to others. After this failed, she was full of grief and became hostile towards the other idols.

After Faruru was reborn she became more friendly and generous, as well as more tolerant since she has to take care of Faruru and thousands of Vocal Dolls.

She tends to add "-dechu" to the end of her sentences.
