well in this one you need to do Monika's story, which is to find who the thief is. You need to talk to the students and teachers to get information. After a couple of days, a scene will happen during the morning or afternoon (i am not sure) were a group of students surround a guy, when you approach and try to stop this, you be given two options, select the "show fangs". Afterward you find out the group is the disciplinary department and you talk to Oden in Class 2A who will provide additional information to help you and provide some about people and things in the school. Now after gathering all the information (including the evidence, who the thief is, how and why there did it) now you can meet the practical, select thief and select Dies, Mike and Oscar (that's if you have talked to them all) and then you be given the option your looking for.
