He hoped to destroy the Empire and create a world where his sister could live happily. All this became no longer out of reach with the appearance of the mysterious girl CC. At this time, Suzaku also appeared in their lives again, but the cruel reality made it difficult for childhood friends to relive their childhood memories. There is no justice and evil, darkness and light here, only difficult choices and unpredictable tomorrow.
