Eternano Vents

Eternano Vents (エーテルナノ通気孔 Ēterunano Tsūki Kō) are a wilder mix of Holder Magic partly permanent accessory, partly internal/fully integrated Lacrima.

Description
The Eternano Vent serves to supercharge the user’s Magic Power or physical abilities by collecting and storing Eternano, serving as a combination battery pack/capacitor. However, in order to operate at full capacity the Eternano Vents actually have to replace a portion of the user’s body, like a magical prosthesis. The vents collectively emulate the functions and tasks of the organs the Mage is missing from the cored-out portion of their piercings. They pass along blood, nerve signals and so on to their respective destinations. They provide appropriate structural support and perform each and every task flawlessly. Basically the Mage’s body doesn’t know their missing anything. Depending on the Mage’s preference sometimes this amount seems minimal, and sometimes it’s more dramatic.
