After considering to enter the Chūnin Exams, he recolored his bow because he thought, black would be better for camouflage. Despite its looks and relatively smaller size, the bow is extremely heavy and not suitable for everyone. The bow has often slowed down Eiki. Recently, he has modified the bow to look more mechanical and has greater precision with it than before. The bow is now capable of folding on itself (most likely for either easier transport, concealment, or both) that can be quickly snapped into its 'armed' form. It also has an easy focus sight. Despite this, the bow is far from being indestructible. It seems that he also has an exact duplicate of this bow at home which is supposed to serve as a replacement if anything were to happen to his current bow.
