Letternode

The Letternodes (レターノード) are a series of 26 devices which grant their users power over all things imaginable. They are used by the Riders in Kamen Rider Aiz.

Overview
The Letternodes come from Shangri-La, an alternate world which has power over the normal world, and are the condensed manifestations of people's whims and desires. These can either be generalized desires or specific (ex. the desire to alter or change things, or the want of nuclear power). Having two or more Letternodes allows a user to transform into a Rider through the use of the Divine Driver, though even a single Letternode gives a user powers reaching beyond that of an average human. Through the collection of all 26 Letternodes, their user will be granted a wish that they can use for any purpose.

The Letternodes are divided into two categories: A through M are Major Letternodes while N through Z are Minor Letternodes. This is to denote the limit of Riders capable of participating in the Wish of Shangri-La. In order to transform into a Rider, one must have two Major and Minor Letternodes which have high affinity towards each other before being able to use any combination of Letternodes (ex. one must use Alter and Zen first in order to use any other Letternode with Alter).

The Beasts are a byproduct of the Letternodes, being literally powered of them. In order to obtain their Letternode, a human with another Letternode or a Rider must defeat them.

Design
A Letternode is comprised of the following parts:


 * Node Activator - The Letternode's activation button, located behind the Facewheel. Pressing it by itself allows the user to utilize the Letternode's specific powers. In conjunction with the activation of another Letternode, it summons the Divine Driver and allows the user to transform.
 * Facewheel - The face of the Letternode, which displays the letter it belongs to (ex. the Alter Letternode has the letter A on its Facewheel). It is separated from the rest of the Letternode body by the Radiant Ribbon, allowing it to twist left or right. By itself, the twisting of the Facewheel does nothing; only when in the Divine Driver do these actions active something. By twisting to the lefthand side, a Rider can summon either their Rider-specific weapon or an attachment for their weapon. By twisting the Facewheel to the righthand side, a Rider can activate the Letternode's specific powers, as the Node Activator is inaccessible while in the Divine Driver.
 * Radiant Ribbon - A thin translucent strip separating the Facewheel from the main body of the Letternode. When two Letternodes have been inserted into a Divine Driver, the Ribbon sparks before shooting out an iridescent burst of light out in order to envelop the user and transform them into a Rider.
