<p>Autumn is just around the corner, and it&rsquo;s finally time for Forge Eizo to build a bathhouse! Blacksmithing is exhausting, sweaty work, so who wouldn&rsquo;t want a natural hot spring to soothe away the aches of the day? As the family begins construction, Eizo realizes he doesn&rsquo;t have a way to contact his friends outside of the Black Forest&mdash;it&rsquo;s not like texting has been invented yet. Right on cue, Camilo proposes a solution to this problem, but it comes with a catch: Eizo must take in another apprentice. Enter Karen Katagiri from the Nordic region! Eizo prays that Karen doesn&rsquo;t press him about his fake backstory, but as he gets to know her, he can&rsquo;t help but feel that something is amiss... Are her intentions as pure as the steel she wishes to forge? Or will she thrust a dagger into the heart of Eizo&rsquo;s family?</p>
