My grandfather owned a martial arts academy in the past, so I wanted to learn martial arts from a young age. Later I also found a master to teach me martial arts, but I was much behind because I didn't have much time to spend on martial arts. However, I once saw a sword awarding ceremony inside the martial arts hall, which was very shocking and I also wanted to learn sword since childhood. As the progress of martial arts is behind, I still can't learn sword until now, so I made a long sword as a souvenir for this project.
