Characters are stellar, not a single one I'm not interested in. Personally, not a fan of the femdom stuff with Akane but oh well, that's just my taste she's still a great character.
Never trust the wierd purple haired catgirl other than that you are right not a single character in this line up is bad. Love the doggo and the redhead catgirl the best but I am bias as all hell when it comes to that. Dog/wolf girl slightly edges catgirl out of the top animal girl but again bias as hell.
