Dangerous things come in small packages.

Kite (1998)

Directed by Yasuomi Umetsu

Sawa, orphaned as a child by murderous thugs, now targets the scourge of society as a trained killer for a mercenary syndicate. Coquettish and capable of unimaginable violence, she's grown into the perfect weapon — but doubt takes hold in Sawa's mind when her fellow assassin, Oburi, decides he wants out.
