Lil Avenger

About
A rare gal monster (There is only one in the whole world), she always enters a treasure box and whoever opens that treasure box can order her to assassinate the one they want. That's the reason for her name, Fukushuu mean "revenge" in Japanese. She is known to be fairly tough and extremely persistent, but she is not particularly clever.

To set a target for assassination, you must have one of the following: Once her assassination target has been set, she will try to set up traps to distract her target, leaving him vulnerable. If this fails, she will try to fight him directly, and though upon defeat she will retreat, she will always eventually return until her contract is fulfilled, no matter how badly she has been beaten. However, due to her simple-mindedness, she can be tricked fairly easily.

 * Target's personal belonging (that have target's smell)
 * Let her see the target directly

History
She was once contracted by Bird Lithfie to kill Rance, as Bird had found her by accident and when asked for a target, he almost blurted out his foe's name. However, she was unable to beat him and his allies and only "accomplished" her mission when he faked his own death.
