OMG Akuri is so freakin' adorable. 11/10, would want as my own child.
As for the bath scene... HAH. Love it. The ladies reactions are hilarious. And if you ask me? Nothing wrong with being thirsty for the guy you want. The problem is that Kuruto is just so friggin' pure that he's even more pure than the sweet and innocent (okay, but only marginally so) princess.
The only way that it could have been better was for Akuri to say or do something really pure and innocent that somehow makes it all the worse for the unintentional double entendre.
