It's a... very... interesting story? I mean... It's about 2 human-beasts. They are from different planet and they seek for information as secret agents on Earth. They go to school on Earth. 1 human-beast is a human-goat (but might be mixed with wolf too - his eyes change shape and colour during heat) and the other is a human-wolf. They both can go in heat. The goat is actually stronger than the wolf. The goat basically rapes the wolf cause he's in heat. Eventually they start to go out. Oh and the goat beast is actaully a chimera: goat - wolf best.
