What's the difference between Kazuaki and Kazuaki-Kun in Hatoful Boyfriend? Well, that's what I'll be talking about in today's blog post! I'll be avoiding any spoilers, though. Now then, on with the post! Although most fans already know the difference between the two, those who just play the games may have missed the connection. The first connection between the two can be seen in Holiday Star. Although the main story doesn't really make it clear that the two are connected, other parts of the game hint at the fact that the two Kazuakis are not the same. Because of this, the creator of the series calls them by different names to be able to tell them apart. The Kazuaki that appears in the first game is simply called Kazuaki, and the other one is referred to as Kazuaki-Kun. If any of you would like to know more about these two, I would suggest playing the games yourselves. The connection between these two is pretty spoiler heavy, so it's better to find out on your own. As a little bonus, I will be including a picture of Kazuaki-Kun below. Enjoy!
