Agito (power)

The Seeds of Agito are a special blessing given to passengers of the Akatsuki ship and some other people in Kamen Rider Agito. The seeds were essence of the Overlord of Light after his demise at the hands of his brother the Overlord of Darkness. The seeds purpose was for humanity to evolve beyond the Overlord's control. Akatsuki however was attacked by the El of Water under orders from the Overlord of Darkness to wipe out any vessels refusing to let his brother's ambition come into fruition. Fortunately Tetsuya Sawaki (now known as Shouichi Tsugami) fought the El as the 2nd Agito while being thrown into the ocean with him.

The seeds grant their users the power to become Agito as well as other abilities like psychic powers. Still only four individuals were able to use the transformation and of them only Shouichi and his older sister Yukina Sawaki were able to become perfect Agitos but Yukina commited suicide due to her traumas. The other individuals were Ryo Ashihara and Karou Kino. Ryo gained his transformation after a near fatal accident and became Kamen Rider Gills, a flawed and more feral form of Agito. Kino had received his transformation from Akatsuki but he too gained a flawed and disillusioned form of Agito, Another Agito. Near the end of the series a young woman named Kana Okamura also started to become an Agito and attempted to do the same thing Yukina did until she was stopped by Souichi and the newly named Tetsuya.

The seeds also appear to have the power to revive individuals who already possess a Seed of Agito as shown when Koji Majima relinquished his seed to revive Ryo.
