Seiken no Blacksmith

Synopsis

After confronting a citizen who was haggling at a tamahagane merchant, Cecily Campbell, a member of the Knight Guards of Housman, attempts to stop Jack Strader, a mentally unhinged war veteran, from attacking civilians. After her sword is busted in the fight, she is saved by Luke Ainsworth, a skilled blacksmith wielding an unusual curved sword called a katana. Before she can thank him, he insults her skills as a knight and leaves. Cecily learns the advanced skills necessary to repair her sword have dwindled among the cities blacksmiths in favour of cheaper mass production techniques, so she becomes determined to have Luke forge her the katana he uses. At Luke's home where he lives with his friend and assistant, Lisa, Luke refuses her request, stating he only forges those katana for his own personal use. A nearby group of soldiers are attacked by monsters being controlled by a man in a black cloak who wants the treasure they are guarding. Luke easily slays the monsters with his katana, whilst also saving Cecily again, so the cloaked man transforms one of his allies into a demon who destroys Luke's Katana. While Cecily distracts the demon Luke and Lisa use magic to forge a new magical katana in mere seconds.
