A terrifying entity that destroys the stars of the universe.
Originally, it was born as something like white blood cells in space, but it malfunctioned and began to destroy even harmless stars.

1300 years ago, it approached Earth and was banished by the previous Rosso, Bull, and Grigio.

Originally, it had a gaseous form, but it was crystallized by Mio Minato and materialized in the form that resembles a dragon. It moves as if floating by emitting anti-gravity from its legs.
