From the bloody shadows, demons surge. Cities fall. The sky burns.

Long held in fragile balance, the forces that shaped existence are now tearing it apart. As cracks form between realms, demonic legions pour through, merciless, endless, unstoppable.
OnirO is a brand-new action RPG forged in the spirit of classic hack ‘n' slash games. Reimagined for modern players, it delivers fast-paced combat, deep class customization, and a dark fantasy world filled with dangers, secrets, and power.
Explore a land where solemn gothic ruins merge with the elegance and mysticism of ancient Eastern traditions. From cursed temples to shattered citadels, OnirO offers a rich, haunting atmosphere like no other.
Fight back the tide. Master forbidden abilities. Forge your own path through chaos.
What rises from the ashes of balance… is entirely up to you.
