Ring Fighter: Pattern Ring

The human spiritual world is suddenly invaded by alien species. As time goes by, the spiritual world merges with the real world. The arrival of alien species has broken the peace of the contemporary world. Just when humans were at their wits' end, tattoo rings appeared. The "ring warriors" picked up their tattoo rings, fought against alien species, and tried their best to protect the peace of society. Among the ring fighters, some were tempted by the powerful power of the ring and wanted to use the power of the ring to rule the world. When the world falls into chaos, who can be the end of this battle?
