Horizon Ariadust

Horizon Ariadust is the central heroine of Horizon in the Middle of Nowhere and the childhood friend of Toori Aoi. Her soul is placed in an automaton body after her death, and fragments of her emotions become the powerful Armaments of Deadly Sins.

Horizon Ariadust's restored identity

Initially emotionless and analytical, Horizon slowly recovers the capacity to make personal choices. Toori's determination to restore her feelings helps her confront whether identity depends on memory, emotion, or the will to live.

The Logismoi Oplo and her bond with Toori

As P-01s and later Horizon, she controls the Logismoi Oplo and serves as a political symbol for Musashi. Her relationship with Toori drives the effort to reclaim her emotions and challenge the powers governing the Testament world.
