Animation is great and enticing! You should really try to make some Actual Newgrounds Anime with that animation, my friend!! :D
This was very well made and funny :D. Only thing I would suggest is maybe reworking Mr. Blacksmith a little. He really doesn't look like he would even be a blacksmith's apprentice, let-alone a proffesional blacksmith. Now, I'm not saying you should make him some burly and hairy man covered in scars. I just think he should at least have a little build to him, and maybe a little more rugged of a look. Now you don't HAVE to change anything about your character at all. If that is how you want him to look, then that is how he should look :). I just feel you should meet in the middle, somewhere between stringy bookworm and nicely built blacksmith :P.
Am I the only one who, as soon as he accidentally grabbed her boob, thought "Love Hina" ? ._.
This gets a 5 and 5 stars because of Rina-chan's voice acting beautiful!
ilol'd. Did you?
