From Yaoi Sekai:
“To me, you’re also a woman.”
A cocky sadist with dual personality “Goat” and a head-strong delinquent “Wolf”. One’s unstoppable when his mating period kicks in! Today, he’s in for sex even if it’s by force! And the other one’s too lewd for a beast that even a woman would be put to shame!?
A planet called Serian, which believes to be a twin of Earth, is where human beasts Yagi and Okami live. They both entered high school and was sent out to an infiltration training together. They were once close with each other but now, there’s nothing but fights between them whenever they open their mouths.
The story starts three days after they’ve arrived on earth prescribed with human shifting medicines and mating prevention pills. Incidentally, Yagi got into his period but his reactions were weird… Worried, Okami tried to talk it out with him but got pulled in and got his nape bitten!?
Also includes: Usagi to Neko no Hatsujou Jijou

On one hand, I loved the art and the premise of this; somehow, even if it's not dwelled upon that much, the idea of two beastmen from a parallel planet investigating Earth was fun, and it would've been even better had that been expanded on, instead of being shoved aside to make room for the many sex scenes.
The problem lies with the fact that ALL the sex scenes are at least dubcon, and one of them is straight-up rape. It would've made this manga so much more enjoyable if Akira wasn't always forcing himself on Kyoga or, if Kyoga did happen to consent, going past his limits. It's sad to see Kyoga begging Akira in vain to stop literally every time they have sex; even when they start dating at the end, it doesn't mean that it's a free pass to ignore lack of consent, you know? Especially not when Kyoga punches him on a few occasions to get him to stop, but Akira doubles down instead.
The rape scene is even worse, because it happens
when Akira is 13 years old and experiences his first heat, and forces himself on Kyoga (who's implied to be around the same age) right after Kyoga saved his life. This experience is so traumatic that Kyoga blocks it out entirely, and then has to deal with the fact that his "friend" ices him out with no explanation.
It really wasn't hard to make this manga good—just make Akira more gentle and less driven by instinct, and have them talk things out instead of ignoring them. There is a good foundation there, but it's a shame that it's buried under all the dubcon sex where Kyoga's clearly not enjoying it and Akira keeps doing whatever he wants.
There's nothing really special about this manga from the dull formulaic story to the bland cookie-cutter characters on top of some very sloppy inconsistent worldbuilding, and personally I didn't find the smut to be that sexy either. It's graphic and lengthy but gets boring pretty fast; Owaru does it better. The fact that there was a lot of dub-con sex also doesn't help. An average work at best, if not quite mediocre if we wanna get real, but since there's soo much hardcore sex I have no doubt lots of people will eat this right up.
