Dr. Kyofu's Living Specimen Research is a repeatable quest given by Dr. Kyofu.
She will ask your main character to capture different kinds of pets for her research.
Each time the request is random.
The rewards start at around $8000. But it will increase as your relationship with Dr. Kyofu improves.
Each time you complete this quest, you can gain some relationship with Dr. Kyofu.
You can also abandon the quest when talking to her. So that she may issue a different request. However, that damages your relationship with her.
