Quincy: Letzt Stil

is the last resort for a Quincy using the Sanrei Glove.

Design & Appearance
"One will get burned if he wields a flame too great to control. If you take [the Sanrei Glove] off, you will get an immense amount of power for a short while, but after the surge, you will no doubt...Lose all of the Quincy Powers you possess." - Sōken Ishida

By removing the artificial repulsion to spiritual energy that the glove placed on them, the Quincy user will experience an abrupt increase in power as their reishi gathering abilities (which were greatly increased during the Sanrei Glove training) absorb huge amounts of energy, along with a change in appearance. The Quincy gains a more battle-ready form of the standard Quincy attire, with the Sanrei Glove's bow separating from itself and remaining in the users hand, and what appears to be armor covering their left side and arm. This shoulder armor is a silver color, bearing the common blue Quincy cross, while the white clothing area of the outfit contains rows of parallel blue vertical lines. A blue, flame-like object resembling a quiver of pure reiryoku forms on the Quincy's right shoulder. It collects large amounts of reiryoku, reiatsu and reishi from its surroundings, in essence storing "arrows" or the energy for them.

While in this form, the Quincy will absorb energy from their surroundings at such an alarming rate that they can actually deconstruct spiritual objects, such as buildings in Seireitei.

Use
In such a state, the Quincy is able to fight with extreme strength and speed, and can completely overwhelm an average Shinigami captain. It could be seen as the Quincy equivalent to bankai, however this is incorrect; The Quincy: Letzt Stil is definitely more powerful (though to what extent is unknown,) and can only be used once as a last resort, whereas a Shinigami's bankai can be summoned whenever necessary. Uryū Ishida used this form against Mayuri Kurotsuchi after being pushed to his limit. A regular arrow shot in this form was able to injure the captain to an extent, but angered him to the point of revealing his Bankai. Uryū warned him beforehand the next arrow would be three times more powerful, but was halted and surprised by his bankai release. Slowly being affected by the poison in his body, Uryū charged his bow, and fired an incredibly powerful spirit arrow. This arrow was powerful enough to cut Konjiki Ashisogi Jizō completely in half and leave a huge hole in Mayuri's body that destroyed most of his organs, or at least where his organs should have been.


 * 1) Spirit Arrow Augmentation: The power of the users' arrows are drastically increased; a standard arrow was enough to push a Captain, Mayuri Kurotsuchi, into releasing his Bankai. A charged arrow, arguably at full power, was enough to cut Mayuri's Konjiki Ashisogi Jizō completely in half, and continue traveling until it pierced a huge hole into his chest; even then the arrow still had enough power left over to cause large scale damage to the structures in Sereitei.
 * 2) Reishi Dominance: As stated by Kurotsuchi, Uryū was no longer using collection of spiritrons, but he now had "dominance" over them. Using the Letzt Stil, a Quincy can go past his mortal limits and break down spiritual structures, such as buildings, for their own power.
 * 3) Vast Spiritual Power: After the Letzt Stil is released, the Quincy is engulfed in a tremendous and powerful blue aura, which is actually their reiatsu being released. Mayuri was shocked at how Uryū's Spiritual Pressure "inflated."
 * 4) Hirenkyaku Augmentation: The Flying Screen Step technique is much faster, allowing Uryū to get a shot on Captain Kurotsuchi with relative ease. Using Hirenkyaku in conjunction with their augmented arrows, a Quincy in their Letzt Stil becomes a deadly opponent to all but the most powerful opponents/threats, as they are now at least stronger than a captain.

Drawbacks
The Letzt Stil is a double-edged sword, as no human body is capable of handling the immense power that it provides. After a short period of use, the Quincy's body will forcibly seal itself off from all spiritual power as a measure of self-preservation, effectively robbing the Quincy of their abilities. The Letzt Stil is only used as a last resort, because even though it is possible to regain Quincy powers afterward, the process is exceedingly dangerous.
