Saibankan

The Saibankan is one of the 12 Saijo O Wazomono grade swords. However, it was not graded until Marine Fleet Admiral Mutsuhiro noticed the sword's extreme strength and sharpness after the timeskip. It is wielded by Taisho Akagi of the Tendokyo Thirteen after he bought it from Tanegamaru. The sword is actually a double sword, as it can be split into two for Nittoryu use (not seen in the picture).

Appearance
The Saibankan is one of the simplest swords in the Tarasov's Universe. It lacks outlines or details and is simply a white hand guard with a black stripe on it. The sword has a simple, black-colored but very fine and sharp blade, enough to injure Akagi's finger. The sheath shares the same color scheme with its hand guard.
