Scanner raped the quality... Oh well.
In this one, you have Yoshimitsu's two masks. The top left is of darkness, top right of darkness. The bottom left is a combination of the two, and the bottom right his his Light Based Weapon, a shield that can be thrown from his arm but is attached by a chain to his wrist. It also spins rapidly, hence the blades.
Some of the many applications of Bahamut xD In short, Yoshimitsu can summon Bahamut into different things with different effects. Here, you can see the Bahamut Handgun (which fires either bullets or short blasts of fire), the Bahamut Guan Dao (which can extend similar to Renji's Bankai) and finally the Bahamut Jet Boots (which Yoshimitsu uses when he can't fly using his Super Transformation).
All sketches, obviously. What a productive psychology lesson.
