Immortal Girls, Ones that can`t die.

[chachazero90]

Ever heard of the series Shikabane Hime(Corpse Princess). the anime started running recently.
Lets use that series as an example.
The main girl who is a corpse princess kills corpses(zombie monsters)however she is a corpse herself in human form.
no matter what kind of injuries she sustains she cannot die.
Seeing her fight while covered in blood looks cool.

Another series is Jack Frost where a girl is the mirror image which gives the ability of immortality and she tends to lose her head(literally) and her body ends up in comedic ecchi poses alot(she`s upset,LOLs).
