Arios, born Leviath Ragna Alviss, was the disinherited heir to a cosmic throne ruled by a sovereign emperor. His uncle’s usurpation forced the execution of Elis, his lover bearing a striking likeness to Angelique Collet. After defeat, he reemerged in the Cosmos of the Holy Beast under his new identity, Arios.

Standing 187 cm tall with a lean 72 kg frame, he possesses light gray hair, multicolored eyes, and AB blood type. Driven by vengeance and ambition, he spearheaded an invasion of the Cosmos of the Divine Bird, rallying followers to harvest energy for reclaiming his birthright. The campaign’s collapse cemented his legacy as a tragic strategist consumed by loss.

In later narratives, he appears as a conditional ally, unlockable only by securing untapped Legendary Energy and navigating meticulously timed interactions across successive playthroughs. Players must strategize dialogue and revisit pivotal locations to earn his guarded trust, positioning him as a linchpin in intersecting storylines. His arc intertwines with themes of fallen nobility and contested authority, though expansions into spin-offs or OVAs lack explicit elaboration in documented records.
