ELFEN LIED
Total Episodes ~ 13
Elfen Lied is really short and it is well done. It is about a girl with psychic powers who is being chased by a company that she escaped from. and that company has other people with psychic powers. The group sends people after her and she battles them. I won't tell too much about it. It is really short it very graphic and has nudity. and I think everyone should check it.
