Overrites

"Ready!"

- Announcement when placed in the Toriiver

An Overrite (オーヴァーライト) is a special transformation device used by Era Saga in order to access his Succession Forms as Kamen Rider Nio. Designed after oshiguma, they are to be placed atop the Toriiver's Form Print before the insertion and use of regular Modifires. They essentially allow Nio to assume two of his forms at once, either "doubling up" to increase one's overall power (and weaknesses) or using two to create more balanced forms.
