God I love this manga so much, it's ridiculous. Everything from the discrepancy of animals in uniform, to the females of all species being pretty girls, no matter their normal size.
Also, this artist really knows how to draw some beautiful hands... Once I noticed it, I can't not look at them.
P.S.: Io = bestgirl. You may have a different opinion, but take comfort knowing that you are simply wrong. Unless you mean Chii, as she's a good second choice. Or the sister of homo-giraffe. Or Miki (President). Actually, fuck it, they are all bestgirl.
