The Nine Year Old Witch

Yume Furusuna (古砂 夢) is the instant bullet of "Time", and one of the main characters of Instant Bullet.

Personality
A master of faking smiles. She carries a gun, and has the means to have herself instantly admitted to a high-level university. Because Kuro, Moroki and Kokage gave her the "reason for existing" that she had lacked since she was a child, she harbors feelings of affection for them. Everything she does is for Kuro Fukase's sake, but the strain in her mind caused by her experiences as a child, the limits placed on her visions of the future, and her role as the Witch are clear for anyone to see.

0 years old
She was born 7 years after Kuro Fukase's birth.

8 years old
She was abandoned in the mountains by her parents, with broken bones and badly wounded. Yume nearly died, but was rescued and taken into custody of a local foster home. After awakening as the instant bullet of time, she was taken in by the Witch (a future version of herself), and began living with her.

9 years old
The Witch (15 years old) died. Yume then met Kuro and the others. After being with them, she traveled back in time five years before the start of the series, to August 21, 2003 - the same day that Toiro died. She then became the Witch, and began acting in secret. Now two years younger than Kuro.
