kudou sachika

The heroine of Animal Jungle's third story, "Ultimate Bishie Paradise".
Sachika is repeatedly being confronted with the predicament of her female friend(s) making up excuses for breaking their promises. Apparently, these turn out to be lies: Not much later, she would find out that said friend(s) in actual fact spent time with one of their class mates, Nakahara Mitsuki, who is an unbelievably perfect boy.
Sachika sees the root of the problem in him. In order to stop being treated this way, she tells Mitsuki that she is going to "reveal his true colours" - finding out his weakness and exposing it.
