Blut (血装 (ブルート), burūto; German for "Blood", Japanese for "Blood Guise") is an advanced Quincy technique that grants one inhuman defensive and offensive capabilities.
By making reishi flow into their blood vessels, a user of this technique is able to drastically increase their attack and defense power. However, despite the significant danger this potentially presents to one's opponents, Blut possesses one major flaw in that the forms of the technique for attack and defense work using two different reishi systems, meaning they cannot be used simultaneously.
|Blut Vene (静血装 (ブルート・ヴェーネ), burūto vēne; German for "Blood Vein")||The defensive form of Blut that grants the user inhuman durability, represented by a faint pattern enveloping their skin, which only becomes visible upon the afflicted area when it is struck. If consciously kept at full power, even attacks delivered by a Shinigami's Bankai can potentially be negated completely.
However, despite the considerable defense afforded by this technique, it seemingly isn't absolute and can be torn using sufficient power.
|Blut Arterie (動血装 (ブルート・アルテリエ), burūto aruterie; German for "Blood Artery")||The offensive form of Blut that grants the user inhuman attacking power. This technique is the only thing capable of ensuring that a Quincy's attacks are able to significantly damage a Shinigami even whilst their Bankai is activated.|
