is the manifested spirit of Izuru Kira's Zanpakutō that is seen during the Zanpakutō Unknown Tales arc.

Character Outline
Wabisuke's spirit takes the form of an emaciated, shirtless man. He carries a large metal ball on his left shoulder and a blade that resembles Izuru's Shikai in his right hand. His pants resemble those of a Shinigami's shihakushō but tied with chains instead of an obi. He is always seen with his head bowed down, letting his hair completely cover his face. The spirit also has a large stone tablet chained to his body that seems to weigh him down; this is reflective of Wabisuke's abilities of doubling the weight of those struck by his blade. He seems to communicate by shaking the chain attached to his metal ball. So far Ruri'iro Kujaku is the only person shown to understand what Wabisuke is "saying" in this manner. Despite this, he is later shown speaking normally when ambushing his former master.

Synopsis
He first appears when several Zanpakutō spirits are in a cave waiting for Muramasa's return. He is then seen along with the rest of the Zanpakutō spirits appearing before the Shinigami that have gathered at the Sōkyoku Hill. Later, after Muramasa returns, he agrees to assist in capturing Ichigo Kurosaki. He appears again just after Kira captures Kazeshini. He taps his Shikai's blade against Izuru's sword four times, weighing it down so much it smashes into the ground. He then cuts his former wielder, sending him to the ground, places his foot on Kira's back and moves his blade towards Kira's upturned head to adminster the killing blow.

Powers & Abilities
At anytime, Wabisuke can manifest the shikai of his former self. It is a standard-sized katana with green hilt and rectangular crossguard with only an omega design on the top and bottom half. It has a straight blade, and where a normal katana would end makes two 90 degree angles, forming three sides of a square reminiscent of a hook. Even more interestingly, the cutting edge of the blade is on the inside of the angles, not the outside.
 * Shikai Special Ability: In this form, Wabisuke's blade doubles the weight of any object it strikes. The ability can affect both inanimate objects and living beings, and is cumulative. For example, the first strike on an opponent wielding a 10 lb sword doubles the opposing sword's weight to 20 lbs. If Wabisuke strikes the sword a second time, the weight of the sword doubles to 40 lbs. Wabisuke can continue doubling the weight of his opponents sword indefinitely. After about eight or nine strikes, most opponents would be unable lift their swords and are brought down to their knees by the weight of their own weapon. Though the potential of this ability is limitless, a small number of strikes to an opponent's blade is usually all that is needed to render them immobile. This is perhaps a poetic effect of Izuru's weapon. Its ability makes it look like he is forcing his opponents to bow their heads in apology for a past decision since it brings his opponents to their knees before him. With them immobile, the hook end of his blade can now show its gruesome function: Wabisuke can decapitate a fallen opponent by holding the square hook beneath his opponent's neck and lifting, like a reverse guillotine.

Enhanced Speed: Wabisuke has shown to be highly fast, able to sneak up on his former partner and repeatedly strike Izuru's sword before he can realize it.
