Kaiser Arts (
The only modern practitioner of Kaiser Arts in ViVid is Heidi E. S. Ingvalt, who is revealed to be the secret identity of Einhard Stratos, a descendant of Hegemon Ingvalt. Einhard has inherited the knowledge of Kaiser Arts via genetic memory, along with the art of Adult Mode transformation and her characteristic heterochromia and silvery-green hair. She is known to treat her heritage with great reverence, claiming that Kaiser Arts are her "everything" and even breaking off a sparring with Vivio Takamachi when she believes that Vivio does not take the fight seriously enough.
In ViVid Strike!Edit
Fuka Reventon becomes a trainee of Kaiser Arts under Einhard's teaching, as Einhard finds that she is talented in striker skills.
