Well there are female and male dogs and cats, i didnt specify their species, its just that all the pets he rolls around are ALL male, except for those 2 instantly forgotten characters. It doesnt really matter If your dogs are male or female, does It? I mentioned to reinforce that theres no harém or romance. You can say that i meant this is a story about a rude dude rolling around with his bros, that happen to be tamed beasts.
But yeah, id say this story had a great potencial but the author constantly forgetting plots and characters is very annoying, specially when he does that in favor of some more repetitive tournaments.
