Aether

Aether (エーテル, Ēteru) is a special Space-Time Ninjutsu created by Tsukihime Uchiha, upon mastering the Chidori, and utilizes the peak of lightning manipulation.

Usage
By exerting their chakra through the clouds and blending it with the energy encompassed by these natural structures, the user can then establish a link between them and that particular lightning. Using that link, the user can teleport anywhere within the vicinity through a lightning strike from the clouds in an instant. Additionally, the user can inflict tremendous harm on a target by teleporting exactly in a position whereby they make contact, thus hitting them with the full force of the lightning strike.

Drawbacks
The user is unable to teleport in areas whereby there are clear skies. However, the user may create the clouds or, in Tsukihime's case, recreate the lightning phenomena through the use of other lightning attacks, thus teleporting through them.
