Reiryoku Absorption is a technique used by the Tōjū, Kirikaze.
While in his mist form, Kirikaze can absorb the Reiryoku of other Tōjū by surrounding them with his mist, entering their bodies, and leeching their power. Upon doing so, his own Reiryoku increases, as does his physical size when he reforms himself. This process is fatal for its victims, who return to sword form due to not having enough Reiryoku to sustain their existence, and is powerful enough to override the Reiryoku absorption capabilities of Ruri'iro Kujaku.
