White reishi spewed from the Infernox Core, which flowed around Gai's left arm before shifting into his grip. The reishi expanded and solidified, taking the form of an oversized elegant cleaver which curved inwards at the backside of the tip, similar to a trench knife, with a black hilt, dark wrappings and a short length of chain at its base. It had an ornately etched base, but its most unique feature was that it had been specially customized with a motorcycle-like gear shift. The sword was taller than Gai was, 1.97 meters. This blade was the Zanpakutō of Gai Nagareboshi, Suigetsu.
