House Dion

Helian noble house

House Dion is a major noble family of Helio, raised through exceptional mercantile strength and headed by Alexander Dion, Marquess of Helio. Its wealth gives the house influence beyond its home kingdom.

Sophia at the School

Sophia Dion brings the family name to the School. Her offer of protection to Ryuji becomes a demand for lifelong submission once she learns he is a commoner; his refusal makes the house part of the conflict between inherited rank and self-determination.

Connection

House Dion does not take a shown side in Hikari’s civil war. Helio remains connected through Atlus, while Sophia’s school relationship continues to place the family within the wider human network.
