Reiseī

Vital Force (生命力 Inochiryoku) is the energy for attacks using reiatsu converted into a usable form.

Origin
Rediscovered by both Seireitou Kawahiru and Hikaru Kurosaki, this form of energy allows the use of techniques that transcend the boundaries of Kidō. Seireitou and Hikaru created techniques that utilized Vital Force in order to expand their repertoire of attacks. Hikaru later discovered that anyone who has a Bankai can learn to manipulate Vital Force as in the case of his younger brother, Mizu Kurosaki. Hikaru theorized that this may have been something limited to the Kawahiru and Kurosaki clans, but he was later disproved when Nodoka Kumori and Saya Kōkiaru began exhibiting signs of manipulating Vital Force. Hikaru was able to come to a conclusion that anybody with Shinigami powers and a Bankai or Bankai-like abilities could use Vital Force. More discoveries have yet to be made.

Behind the Scenes
Vital Force is a new take on Ki. This needed to be made to categorize the new powers Hikaru and Seireitou used in the Yonkō Reunion on the Fields of Elysian. Despite it's name, Vital Force does not have anything to do with Life Force initially. At this point, it is merely converted reiatsu.
