The specimens seem to exhibit strong sexual excitement towards female servants... However, manual masturbation and semen extraction devices have not been able to produce an ejaculation. Specimen #602... a bicorn captured during the last battle. Commencing the collection of a semen sample. For that reason, I am using my own reproductive organs to perform the sample collection.Due to the ethical considerations of this experiment, I have kept it secret from the rest of Chaldea... I am conducting this experiment on my decision alone. I was only able to prepare one condom, designed to collect samples and withstand any discharges of magic. However, I have deemed that this will not be problematic. Commencing experiment. With this experiment, we will confirm the presence or absence of the reproductive abilities of the specimen. Hopefully, this can shed light onto their seemingly infinite population.
