Tokyo was suddenly assaulted by the Great Collapse! The moment they heard it, everyone in the city fell into a coma. When they awoke, Tokyo was enveloped in a red mist. Though some plotted to escape, not a single person has made it through the red mist alive, and Tokyo has become inaccessible. Tokyo is now a shadowy and inaccessible city from which there is no escape! Five months later, the very last person still in a coma, univeristy student Kamina Chihiro awakens, and curtains rise on the fierce Vermillion legend!
I want to resist fate. I want to save my friends from death. Hoping to achieve these goals, Chihiro decides to work with agent of Chaos Yuri. He asks Marie, Tsubaki, and the Guardian State to fight with him. Rather than destroying Tokyo, he believes the best option is for everyone to work together so the Heroic Lindeage survives. However, fate does not abide such naive thoughts, and instead leads Chihiro to the worst possible end...!
Chihiro is betrayed by Yuri and deserted by the Guardian State. No matter how much he fights them, his prophetic dreams of despair keep coming true. Despite this, he continues to desperately struggle to change fate. Chihiro's behavior inspires Kakihara to look into his past again. Did Chihiro really kill is own father?! What truth is hidden within that bloody tragedy?! Meanwhile, Chihiro dreams of Kakihara's death.
The AVAL Science Foundation has been attempting to cause a Second Great Collapse by installing artificial keystones throughout the city! At this rate, everyone in Tokyo will be transformed into monsters, and the city will become a hellscape! In order to stop their plot, Chihiro and his friends head to the Infinity Theater where Kark Kaburagi is performing a concert. As the reaper's deadly melody rings throughout the theater, total war breaks out between Chihiro's friends and the AVAL Science Foundation. Will they be able to stop the Second Great Collapse?!
