next step: Kourin will find a new artifact; a strange, special clothing made of mystical, very thin gold fibers, said in some legends to have been crafted by humble, skilled artisans for an emperor. Such clothing has now acquired the property of greatly amplifying one's inner abilities/powers, but it also alter the personality of its user.
Kourin somehow finds it, considering that it's seemingly near-invisible to him and, having difficulties trying to understand its origins, tries it, when he notices an increase in his physical strength..
