Sanrei Glove

The is a powerful Quincy item, in the form of a white glove that extends up the forearm stopping two inches from the elbow. It was given to Uryū Ishida, by his grandfather and teacher, Sōken Ishida.

Training Usage
A Quincy's power can be significantly enhanced using the Sanrei Glove.
 * 1) The glove operates by repelling spirit particles, making it far more difficult for the Quincy to summon their bow. The first step is to simply create the bow.
 * 2) Next, a Quincy needs to complete a week of intense training in order to be able to use the glove effectively. This is a difficult task, as the user must keep their bow from dissipating, while simultaneously firing arrows as frequently as possible. Even without the glove on such a feat would be taxing on the wielder, and it eventually causes some injury to the his/her hands by the end of the week.
 * 3) After the week of endurance training, any Quincy who is able to successfully utilize their powers while wearing the glove can thus reach much higher levels of power, as they are now far more skilled at collecting Reishi. His/her power, speed and stamina have now all been augmented, to a degree which is at least equal to a higher-seated Shinigami officer (3rd seat - 6th seat.)
 * Sōken Ishida even referred to the mastery of the Sanrei Glove as the "peak of Quincy power." This training is also the basis for the Quincy: Letzt Stil, which may have been what Sōken was referring to.

Bestowed Abilities

 * Enhanced Spirit Weapon
 * Enhanced Hirenkyaku
 * Quincy: Letzt Stil (One Use Only, and removes all of the Quincy's powers afterward.)

Removing the Glove
It is possible to remove the Sanrei Glove, but this is done only as a last resort, when the user is facing an opponent beyond their current level of strength. It was only shown once during Uryū Ishida's fight against Mayuri Kurotsuchi. The glove completely dissipates after removal, since the user is going beyond their limits as a Quincy. The glove should be removed only in the most desperate of situations, or to protect one's pride of the Quincy. After it is removed one can never use their Quincy powers again, unless they are aided by another Quincy (see below.) The Sanrei Glove is the only known way a Quincy can gain access to the powerful Quincy: Letzt Stil.

Recovery
The only way for a Quincy to regain their powers after using the Quincy: Letzt Stil is to first exhaust themselves both mentally and physically, then be hit exactly 19 mm to the right of their heart with a spirit arrow. After this, a pentacle-shaped scar will form on the point of impact, and their powers will be restored.
