Dragon Crest (龍紋鬼, "Dragon Crest") also known as The great teeth of the yawning dragon is a special weapon that belongs to Takuma, a member of the Yotsuki Clan . Originally not much was known about this Odd weapon, until Takuma revealed the Dragon Crest was once his clan masters weapon tell Takuma killed him for it many years ago.
The Dragon Crest is a powerful weapon, Dragon Crest is a three over-sized weapons connected by an equally large chain. Takuma's two main weapons are a Chinese Monk's spade and a standard Guan dao. Both have a traditional horsehair tassel at the hilt and a long cylindrical weight for a pommel. The pommels are connected by a heavy chain to the center section, which resembles an axe-like blade with a parallel handle forged into the blunt end and a dragon crest on one side of the blade. Despite all three weapons being of near-ridiculous proportions, Takuma wields them easily. Takuma usually holds one blade in each hand and lets the central portion "rest" on his back, though he will occasionally spin the entire configuration about using the center handle as a pivot.
