Amunesu

A virus who particularly targets pedophiles because she believes that pedophilia is an illness. She's a famous enough virus to be named Amunesu before Yuuichi met her, like the three other main viruses.

By planting child pornography into a person's computer, without the person knowing of course, she then reports about how the person is in possession of said material. A few days later, the police will come into the person's house to investigate. Even if the end result ends up without a convinction, the person's family and neighbors will give the person a look of disappointment.

However, if she is told that she has a feminine charm that isn't related to her being a loli, she will accept it, but in a tsundere-like fashion.
