Conductive Paper

Conductive Paper is a piece of paper that can be electrically-charged and be used for various purposes. A very rare item sold in stores, most people hire a person to make the paper due to the dangers it brings about. Until broken, the paper is able to recharge infinitely as long as it has been electrically charged.

Appearance
The Conductive Paper has no unique outward appearance, being a piece of typical paper that one could write on, make origami, or anything the buyer wishes to do with them. The paper has a special unknown material that allows it to retain electricity.

The bigger the piece, the bigger amount of electricity that can be stored.

Usage
The usage for this certain item varies between consumers. Most people generally use it as a power-source for a small period of time, or, just use it to write on due to people mistaking it as a special type of paper, and only consider it to be an expensive piece of paper. Known usages of it include: shock opponents temporarily by sticking it onto them, gluing it beforehand, writing or anything of the form, eating it, or using it to power something up for a fixated period of time.

Tsukuru
Tsukuru's usage for Conductive Paper varies. Outside of battle, he uses it for writing purposes such as needing to remember something for later, drawing, or to make origami out of it. Typically, when he eats the paper from his notebook, he states that he's doing it so that he can preserve the memory, allowing him to remember it forever. However, this is false, as his true purpose for eating the paper is so that he may charge himself up with electricity.

Within battle, Tsukuru displays abilities of discharging electricity from his body in large quantities. To do this, however, Tsukuru spent most of his time being electrocuted by lightning so that he'd be able to develop a "resistance" to it and absorb it within his cells. Engulfing Conductive Paper allows Tsukuru to super-charge his spells and have electricity course throughout his body, allowing him to make it seem as though he's using a Devil Fruit, but in actuality, it's just discharge. Over time, he's found several uses to use it within and outside of battle.
