Aside from murdering, she also likes to "toy" with anyone she dislikes - "toy" being in actuality, torture. Once done with torturing those who have crossed her path, she is known to crucify them upon blood-red crosses until they die. As mentioned by Defect Mogeko, Moge-ko enjoys cutting up and eating people, alluding to the possibility of cannibalism.
As stated in some notes found in the bonus room, Moge-ko has a thing for tails and thighs; this is said to be top-secret information.
